Background of the invention

This invention relates to the engine, specifically high-pressure engine design, comprising engine block, head and at least one piston fitted on con rod, linked up with drive shaft installed in the engine block.

Current state of the art

Currently, a variety of engine designs using pressurized fuel are known.

Patent CS 13270 describes two-stroke engine, with forced fuel intake using pressure into the space in injection valve body. Then, the fuel will be injected using fuel pump into the combustion chamber. Engine control will be provided by throttling injection pressure in the valve bushing. Basically, this engine is combustion design, with emissions into air, which is the main drawback of this engine.

Patent CZ 47675 describes additional three-stroke locomotive engine This engine is intended, particularly, for high-pressure locomotives, three-point suspension of the tilting frame of axle wheels, and three-point bearing of the crankshaft, in which the internal cylinder has been shifted to one side off the frame centre to allow position of the shell journal of the third suspension point in frame centre at the side of horizontal guide, whereas the driving wheel on the axle has been shifted to the opposite side to allow the centre of gravity to be in the centre plane. Robust structure of this engine, associated with its intended purpose is a drawback of this engine design.

Patent CS 152520 describes pressure rotation engine designed as a hollow, closed cylinder, with concentric shaft and at least one fixed obstacle, one component of the cylinder and shaft pair being rotation design and the other being stationary, where the hollow cylinder has at least two obstacles that can be shifted into the inner space, which obstacles, like the stationary obstacle on the shaft have a shape corresponding with inner profile of the hollow cylinder; in opposite walls of the stationary obstacle are channel orifices for intake and draw off pressure medium, connected with source of the medium and surrounding space via a shaft. Lower efficiency is a drawback of this engine design.

Patent CS 172036 describes rotation pressure engine with lamellas and internal rotor fitted eccentrically in the stator, comprising outer rotor fitted coaxially with the stator, on which , eccentric fit in the stator, comprising outer rotor fitted coaxially with the stator, onto which inner surfaces of the polyhedron-shaped shell fit the lamellas in 90° angles, with synchronized revolutions of the outer and inner rotor. Opposite lamellas are connected with each other. Drawback of this engine design is too sophisticated design and also doubts on the possibility of industrial use of this engine design.

The information above provides evidence of obvious drawbacks of currently implemented technology. The objective of the invention is design of a simple, efficient engine producing no emissions.

Summary of the invention

The drawbacks described herein, will be, largely, avoided and the objective of the intention will be achieved by an engine described herein, particularly high- pressure design, comprising block, head and at least one piston fitted on con rod, connected with the driven shaft, fitted in the engine block, which engine can be summarized as follows: the head comprising at least one operation chamber and at least one intake chamber, connected with the operation chamber with at least one control valve, intake chamber being connected with the source of pressure medium and the operation chamber being connected with the cylinder having at least one exhaust valve.

Advantageously, the piston has at least one exhaust valve. Most advantageously, the exhaust valve has a draw rod on which a spring and sealing cone are fitted, the cone fitting onto the seat and the draw rod having seating surface. The piston has at least one flexible stop.

Advantageously, the cylinder contains exhaust surfaces and at least one exhaust orifice.

Advantageously, the exhaust valve has a body in which the draw bar is fitted, with a spring and sealing cone being fitted on the draw bar, the cone fitting onto the seat, the exhaust valve comprising by-pass channel and intake channel and the draw bar having seating surface.

Advantageously, the control valve comprises control element, including draw bar fitting onto the seat. Control valve operated by solenoid inter-connected with vehicle steering system.

The source of pressure medium can be replaced. Pressure medium source, advantageously, being air.

The engine as described herein is environmentally friendly owing to its driving medium, having no emissions, thus contributing substantially to reduction of air pollution and against global warming.

Description of figures on the drawing

The invention will be explained using a drawing, in which fig. 1 shows sectional view of the entire engine.

Example of the invention design

High-pressure engine (Fig. 1) comprising engine block 1, head 2 and two pistons 3 fitted on con rod 4, connected with (not shown) drive shaft, fitted in engine block

Head 2 contains one operation chamber 5 with pressure ranging 15-30 atm and one intake chamber 6, connected with operation chamber 5 using twelve control valves 7. Source of pressure medium 8 (pressurized air) is connected with intake chamber 6. The supply 8 of the medium can be replaced. Operation chamber 5 is connected with each of the cylinders 10 using individual intake valves 9.

Each piston 3 has four exhaust valves H.

Each of the cylinders 0 contains one exhaust orifice 12 and four stop exhaust surfaces 3J_.

Intake valve 9 contains body 13, with draw bar 14_ inside; spring 15 and sealing cone 16 are fitted on the draw bar, sealing cone 16 fitting onto the seat 17; intake valve 9 comprising also by-pass channel 18 and intake channel 19, and seating surface 20 on draw bar 14. Control valve 7 comprising control element 21, consisting of draw bar 22 with cone 23 fitting onto seat 24. Control valve 7 is driven by solenoid 32 connected with vehicle steering system.

Exhaust valve H contains draw bar 25, on which spring 26 and sealing cone 27 are fitted, sealing cone 27 fitting onto the seat 28, draw bar 25 having seating surface 29.

Piston 3 is fitted with at least one flexible stop 30.

Operation mode of the engine can be described as follows: pressurized air comes to the intake chamber 6. From there, pressurized air comes into the operation chamber 5 via solenoid-controlled by-pass valves. Then, pressurized air is supplied, in turns, into the one or the other cylinder 10, in such a manner that the piston 3 being in top dead centre pushes on the fitting surface 20, thus opening intake valve 9, through which the air comes into cylinder 10. As soon as piston 3 starts moving to the top dead centre, intake valve 9 will close. As soon as piston 3 comes close to top dead centre, fitting surface 29 of valve H will fit onto exhaust stop surfaces 31, exhaust valves JM will open and excessive air will escape from engine block 1_via exhaust orifice 12. These actions will repeat cyclically. industrial utilization

The engine as specified herein can be used for driving in various applications, particularly means of transport.
