BACKGROUND OF THE INVENTION Field of the invention

This invention in its embodiment as a rotary internal combustion engine would be the first truly significant new internal combustion engine design since the Belgian-born engineer, Jean Joseph Etienne Lenoir in 1858 invented and patented (1860) a double-acting, electric spark-ignition internal combustion engine fueled by coal gas.

In 1863, Lenoir attached an improved engine (using petroleum and a primitive carburetor) to a three- wheeled wagon that managed to complete an historic fifty-mile road trip.

Alphonse Beau de Rochas, a French civil engineer, patented but did not build a four-stroke engine (French patent #52,593, January 16, 1862).

In 1876 German engineer Nikolaus August Otto invented and later patented a successful four-stroke engine, known as the "Otto cycle engine". Otto built the first practical four-stroke internal combustion engine by incorporating a compression cycle.

That was followed by the invention of the Diesel engine by the German engineer, Rudolf Diesel in 1896. Both of the latter are basically the same design: four (4) and two (2) cycle reciprocating pistons within straight cylinders in various positions. All these men changed the form of transportation for the entire world. Then came the four cycle Wankel off center eccentric (not a true rotary) engine invented by the German Felix Wankel in 1954.

Pryor to Mr. Wankel the Englishman Sir Frank Whittle registered a patent for a jet Engine, he and the German Dr. Hans von Ohain are both recognized as being the co-inventors of the jet engine. Each worked separately and knew nothing of the other's work. Hans von Ohain is considered the designer of the first operational turbojet engine. Frank Whittle was the first to register a patent for the turbojet engine in 1930. Hans von Ohain was granted a patent for his turbojet engine in 1936. However, Hans von Ohain's jet was the first to fly in 1939. Frank Whittle's jet first flew in in 1941.

The Revolving Piston Rotary Valved Dynamic Displacement Expansible Chamber device embodied as an internal combustion engine overcomes the limitations of gasoline as a fuel and combines the Positive Displacement of the conventional Otto Cycle engine with the dynamic effect of the Jet Turbine engine yielding high torque at low RPM. This device is a new technology that would not displace the current fuel supply infrastructure but would facilitate a shift toward more renewable fuel sources thus having a very positive effect on the environment by helping reduce Green House emissions and because of its efficiency, material cost and relative weight to power ratio etc. This invention in its embodiment as a Rotary Expansible Chamber Device overcomes all of the limitation of other such devices

Advantages: More durable and efficient because of it's rotary compartmentalized design that can retain a measurable and constant fluidic volume, as an expansible chamber device it uses minimal pressures and volumes to function and power. This design does not permit the loss, waste or escape (a type of blow by) of fluids before they complete their function as is the case with axial and centrifugal pumps and turbines. This configuration is as a true rotary and thus eliminates the need to overcome inertia and saves momentum while eliminating vibration and displacing more fluid volume per rotation at higher pressures than conventional devices This invention combines the effects of a positive high pressure displacement reciprocating piston pump and or motor with the high volume flow and the dynamic effect of a jet engine without fluidic waste, is much easier to manufacture and has very few parts.

Objects and Advantages

A. This engine is more efficient for the following reasons:

1. It is perfectly rotary (unlike the Wankel engine).

2. It combines the positive displacement of a conventional internal combustion engine with the dynamic effect of a jet turbine engine hence the term Dynamic Displacement.

3. Utilizes, does not waste low pressures (contrary to the minimum pressure required by a turbine.

4. Does not utilize a reciprocating motion that wastes energy changing directions (momentum, impetus, inertia).

5. Does not waste energy in cycles such as the four (4) and two (2) cycles of the conventional Otto, Diesel or Wankel engines. In the four (4) cycle engine only one (1) out of four (4) cycles provides power.

6. Does not waste power on a compression cycle.

7. Does not waste power on conventional cam shafts.

8. Does not waste power on conventional valves and springs.

9. Can function without a starter.

10. It can utilize excess heat that would normally be wasted (steam power assist and Thermoelectric devices). In conventional engines the radiator wastes 33% of the fuel's energy (more adiabatic).

11. Utilizes turbo charger(s) to supply oxidizer (air).

12. Utilizes electric fuel pump.

13. Utilizes flywheel effect.

14. Can utilize ultra high efficiency lubricants permanently bonded to critical surfaces with coefficients of friction of only 0.001 as opposed to the conventional 1.0.

15. The possible combinations of various versions that increase efficiency. 16. Design permits the complete control of ratios of fuel to air.

17. Can be combined with electric motor/generator in a hybrid configuration.

18. Because of the nature of the combustion there is no such thing as detonation, piston knock or pre- ignition. This engine compensates for the deficiencies or limitations of gasoline as a fuel. These being: ratios of air to fuel, its relatively low octane content and the tendency for gasoline to produce detonations, piston knock or pre-ignition.

19. Can use many types of fuel.

20. Utilizes gasoline more efficiently.

B. This engine is more durable for the following reasons:

1. Simple design, less moving parts, smaller, lighter, oblique angles.

2. Rotation only in one direction avoids wear caused by changing directions (180 degrees) on the parts. Reciprocating action tends by its nature to hammer the following parts: connecting rods, rings, bushings, bearings, cam shafts, cams, cylinders, pistons, crank shafts, etc.

3. Design permits superior design and function of the piston rings because of one way rotation.

4. Less vibration.

5. Can utilize ultra high efficiency lubricants permanently bonded to the critical surfaces.

6. Forms strong components geometrically designed for maximum strength (annular shapes, toroids, triangles and cones).

7. Controlled operating conditions of the critical parts.

8. Can utilize new materials such as carbon/carbon composites that can resist higher temperatures yet do not expand as much as metal permitting smaller tolerances at the same time being stronger and more malleable.

9. Because of the nature of the engine and its form of combustion there never is ping, piston knock or detonation. The latter being potentially the most destructive for a conventional engine. Piston knock or predetonation is a form of abnormal combustion as hot gases left over from the previous combustion spontaneously detonate. This knock produces a spike of ultra high pressure, a shock wave that can break pistons or rings and radically increase combustion chamber temperature. This increases the possibility that red-hot glowing metal in the combustion chamber will result in pre-ignition, at which point successive combustion events are ignited not by the spark plug, but by the hot spots. Timing is then completely out of control, leading to further temperature rises and the possibility of melted pistons etc.

C. This engine is easier to manufacture for the following reasons:

1. The toroid cylinder is manufactured in two halves, then is put together with gaskets and bolts etc.

2. The water jackets are manufactured and put together in the same way as the cylinders and bolted on over the latter.

3. The design is simple.

4. Can utilize new materiais and simplified methods.

5. Would be more economical to manufacture.

BRIEF SUMMARY OF THE INVENTION

This invention as a revolving piston rotary valve dynamic and positive displacement expansible chamber device as in its internal combustion mode is more efficient due to the following reasons:

It is a rotary engine in its purest form. It does not waste energy in useless vibration caused by off center rotation. It runs on a single compound cycle; that is, there is no compression cycle, no separate exhaust, intake or power cycle because it all happens at the same time. This engine can use any kind of combustible fluid, even adding water to certain fuels would function. This engine overcomes the limitations of gasoline as a fuel while being more efficient in its use. This invention is more durable due to its simple design with very few moving parts (only two in its basic configuration). This invention is also easier to manufacture because it can be made stamped or cast in two halves, then bolted together or joined in some other way. making it not only easier to build but also more economical.

The invention can be used in many ways. The following is a list of and the functions of some of its embodiments. Its embodiment as a very efficient internal combustion engine is well documented in these pages, so I will go on to mention some of the others. .One of its versions in its internal combustion engine embodiment is that of an air breathing engine. That is an engine that sucks in the air that it will utilize for combustion rather than having the air forced in by some other external mechanical means. In this version, the engine becomes a cycled engine in which not every passing of the piston is imparted by power but rather every other and the spark is timed in a manner as to coincide with this cycle, see Fig. 14. This is one of various versions of this type of air breathing engine and although in this version compression is incorporated into the compound cycle for illustrative and other inclusive purposes; compression is not generally part of the compound cycle as illustrated in various figs. Including Fig. 6 where a back flow pressure relieving and a vacuum release channels are incorporated.

In its embodiment as a pump, as illustrated in Fig. 8, it can be made in many ways. Fig. 8 shows the invention in a two triangular pistons with a conformably shaped square annular cylinder and valve configuration. In other versions of this pump the cylinder can be annular or a torus, the conformably shaped valve can be double; it can have one or a plurality of pistons and rotors and may or may not include a one way pressure valve. It can come in all sizes from nano and micro to macro or gigantic and it can be manufactured of any material that is suitable to its ultimate purpose (metal, ceramics, composites, plastics etc.). The valve(s) in the designs of the pump embodiments and as with all manifestations of the rotary expansible chamber device, open and close allowing the passage of a piston yet isolating it and fluid from the exhaust port insuring that it that it is pushed and flows only in one direction. Imparting power from the rotation of the attached balanced pistons and rotor to turn the axle shaft from some source, wind, engine or motor device etc.. The inlet would draw the fluid into the expanding chamber. Once the fluid is drawn into the chamber it is compartmentalized and sealed in by the valve and the following piston which delivers it to the exhaust port where the valve(s) purge or force it out of the device. All pump embodiments function in this manner.

Conversely the embodiments of the internal combustion engine, the steam engine, the Hydro motor (water engine for hydroelectric and other purposes), the fluid metering devices, the power assist devices, air motors and nanoscopic motors would function in the same manner except that the working fluid or energy would supply the force or pressure to move the piston(s) on the rotor attached to an axle and the rotational power would be derived from the shaft rather than be delivered to it as in the case of the pump As with all the valves in any embodiment of this invention they can be actuated by many means the rotors can be synchronously attached through their shaft to external synchronized gears who's ratios have been determined by the number of pistons and the relative size of the rotor to the rotary valve and in its most basic and simplest configuration the gears cam be incorporated within the structure of the cylinder on the peripheral surface of the rotor and the rotary valve as illustrated in figure 33 etc. In these illustrations the rotor and piston rotation is generally in a clockwise direction but in actuality may not be limited to this.

The above variations and those not mentioned whether in size, materials, embodiments and functions, represent the invention in all of its actual and potential manifestations.

FIG. (1) represents the most basic form of the invention and as with all manifestations of the Rotary Valve Continuous Flow Expansible Chamber and Dynamic Displacement Rotary Devices (RP7VR) they may be powered by a motor, its single triangular piston 9 mounted on its rotor 4 connected to its axle shaft 6 in rotational interaction with its single crescent rotary valve 14 mounted within the smooth inner surface of its rotary valve housing 18 and annular cylinder housing 1 respectively creates a partial vacuum that as it turns draws fluid in through its intake port 3 as the compartmented chamber expands by the effect of the piston 8 traveling through and against said smooth inner surface of the cylinder 1 wall in this case (but not limited to) in a clockwise rotational direction and expelling said fluid by pushing it out through its exhaust port 2 potentially but not necessarily assisted by a one way check valve (not shown) on or near said exhaust port 2. In most cases synchronicity of the rotational interaction between the rotary valve and the rotor with piston(s) is assured and maintained by external meshed gears whose ratios are determined by the relationship and diameters as well as the number of pistons of same (gears not shown) this manifestation might be considered useful as a pumping device such as an artificial heart where the where a viscous fluid such as blood etc. need not be valved contrary to a biological heart there is no contraction and expansion in the usual sense and with very little if any backflow necessitating a valve although a valve may be used.

The gear ratio in this embodiment is one to one (1 :1). Likewise an un-motorized version of this embodiment would utilize moving fluid pressure entering through its intake port (3) to push said piston 9 attached to its rotor 4 connected to axle shaft 6 ratably inserted within its annular cylinder 1 to impart rotational force to its axle shaft 6 thereby powering any of a number of devices.

Additionally In figure 1 the rotating piston 9 interacts with the single crescent rotary valve 14 in a synchronized rotational manner that acts as a piston transfer lock allowing said piston to transit through said valve while isolating and preventing working fluid from re-circulating without exiting through exhaust port 2 and doing its work. The support base / mount 29 secures the annular cylinder housing 1 which in turn supports the rotary valve housing 18, piston tip roller bar 19 attached to the tip of piston 9 seals while reducing friction.

Not shown is the combustor, the spark and the fuel injection devices or respective supply lines. Ratio of valve to rotor is two to one (2:1) respectively.

FIG. 5 shows the invention depicted as a continuous internal combustion engine with double (2) single crescent rotary valves 14 rotationally synchronized with two narrow triangular 8 pistons mounted on their rotor 4 attached to their axle shaft 6 and ratably mounted to the annular cylinder housing 1 said pistons 8 are shown to have piston tip roller bars 19 that reduce friction and wear while sealing the pistons to the annular cylinder 1 thus forming an expansible chamber with water cooling channels 26. Ratio of valve to rotor is two to one (2:1) respectively.

Combustor not shown. Ratio of valve to rotor is two to one (2:1) respectively.

Additionally shown are bolt holes 25, exhaust port 2, intake port 3, axles 6 and rotary valve housing attachment area 35. Ratio of valve to rotor is two to one (2:1) respectively. FIG. 8 shows a cut away front view image of the invention as a pump with double triangular pistons 9 and piston tip roller bars 19 with single simple crescent rotary valve 14 (said valve turns twice for every rotor 4 / piston 9 assembly rotation) within a rotary valve housing 18 in rotary interaction with said triangular piston 9 attached to a rotor 4 and axle 6 in rotational contact with the annular rotor cylinder housing 1 in a free flow dynamic pressure configuration (free flow refers to easy flow design and angles and dynamic refers to gradual interior port volume changes that allow for pressure differences). Ratio of valve to rotor is two to one (2:1) respectively.
