Description:

PUMP AND MOTOR

The Related Art

The invention relates to hydraulic and pneumatic circuit component comprising pump for compression of liquids and gases for generation of pressure power for transportation, store and use of liquids and gases in technology and hydraulic and pneumatic engine to convert pumped liquid and compressed gas pressure into circular motion.

Background of the Invention

Since the circular surfaces of gears and rotor in existing gears and palette pumps are also exposed to pressure, production thereof in big diameter is disadvantageous and in case of operation under high pressure, big size covers are needed. Having too much moving surfaces leads to bypass and leakages and therefore, they cause heating of liquid and gasses and leads to loss of efficiency.

Although flow rate of inclined plate axis piston pump and inclined body axial piston pumps is adjustable and high sealing provides efficiencies thereof, big size in respect to their flow rates and complex embodiment and expensive prices thereof make them disadvantageous.

In regard to radial piston pumps, wearing is accelerated due to friction under pressure and life of pump decreases.

Description of the Invention

Different from the above mentioned disadvantages and from the background of the related art, the purpose of the invention is to enable use as both hydraulic pump and hydraulic engine, as well as use as compressor, vacuum pump and pneumatic engine for compression of gases.

Another purpose of the invention is to convert the friction into contact situation when compared to existing pump and engines and thus to provide a higher capacity for more work with less power.

Another purpose of the invention is to provide progress of cylindrical pallets located on rotor edges by means of rotation on inner surface of the body and to prevent wearing as friction is eliminated, and to enable long life of pump and engine.

In addition to enabling long life of pump and engine, another purpose of the invention is to decrease the heating since it does not allow back movement, and thus to increase efficiency.

Another purpose of the invention is that it enables production of large diameter engines for use in big flow rate pump and heavy power transmission since the pressure does not influence places other than palette due to integral rotation of rotor together with rotor covers.

Another purpose of the invention is that it can be used as motion transmission body in transportation vehicles in addition to the fact that it performs the functions of existing pump and engines more efficiently.

Another purpose of the invention is that it can be used as a compressor to obtain high pressure and as a vacuum pump for gases.

Another purpose of the invention is that construction is easy, and it has longer life against wearing since silent operating parts when compared to piston compressor are in contact.

Detailed Description of the Invention

The inner diameter of the body (1 ) in diameter and height fitting to the desired flow rate is at least three times or more folds of the diameters of palettes (6) operating therein. The number of folds of inner diameter of the body (1) Is equal to number of equal intervals where locations, one is pressure arrester (11), palette crescent cover (21) passes through. Cylindrical palette (6) terminals contain spindles operating in the pallet bearing (7) and on the other end stud (15) bearing extension holding palette gear. Half cylindrical channel (pressure arrester housing) (27) in the outer diameter of central palette (6) and at least 1 mm. distanced from spindle operating in the bearing (7), in axial length is drilled onto the palette body. The part of the pressure arrester (11) engaged into body (1) tightly forms a half cylindrical set in axial length of the boy (1) and in diameter of pressure arrester housing (27) on the palette (6) edge on inner wall of the central body in the absence of palette.

The outer diameter of the rotor (4) centered into main spindle (18) and body (1) should be such that it contacts pressure arrester. The palettes (6) should be housed onto rotor covers (8-9) in the size enabling contact of outer diameter into the body. Palettes holes are drilled on the rotor (3.4.5) edges so as to allow contact in palettes and operation.

The module diameter of the circular module peripheral gear (13) mounted to front housing of the main spindle and peripheral gear holder (20) should be equal to inner diameter of the body (1) in order to provide contact of palette surfaces inside body. The module diameter of the palette gear (14) operating with peripheral gear (13) should be equal to outer diameter of the palette (6).

Upon rotation of the rotor (3, 4, 5) the palettes progressing by means of rotation on the inner surface of the body (1) via palette gear (14) operated with peripheral gear (13) should be mounted in a position taking pressure arrester (11) of the pressure arrester housing (27).

Peripheral gear (13) is secured into its place with fixing bolt (24). For example, the palette made in one to third of inner diameter of the body (1 ) will make three tours around its axis on the inner surface of the body per one cycle of the rotor (3,4,5) and the pressure arrester housing (27) on the palette (6) comes to inner surface of the body (1) three times. Since one time will be closed on the pressure arrester (11), two times will occur on palette crescent cover (21) and the palettes (6) will continue to operate without causing backward or forward deviation.

Palette crescent covers (21 ) are at most half height of the pressure arrester (11 ) in order to prevent circulation of liquid or gas of palette crescent covers (21).

Silent operation should be provided by leaving required tolerance between pressure arrester (11) and palette crescent cover (21) and pressure arrester housing, and inner surface of the body is covered with an appropriate a material other than metal and silent and tight housing is provided in order to help both silent operation and efficiency increase and to provide the rotation of the palettes silently and tightly.

As it can be understood from the figures, the invention can operate in two directions as hydraulic-pneumatic engine and therefore, inlet and outlet holes (22) of the liquid or gases have been designed wide. Palette housing of rotors (5) to be used as engine do not grasp the palettes (6) on all surfaces and is in contact in the center of palette housing provided that bigger than the wide of pressure arrester housing (27) drilled on the palettes.

The locations of the rotors (3, 4) used as pump and compressor in contact with palette is in 4-5 mm wide on palette housing and thus it will decrease the friction area and therefore deemed appropriate.

If it is desired to use the said invention as air compressor, one-way operation will be necessary and it is essential that output hole (23) on the body (1) is as close as possible to the pressure arrester and an axial length long and narrow hole is designed on the outer surface by rounding for discharge of almost al the compressed gas.

Design of peripheral gear (13) and palette gears operating therewith in circular profile is deemed convenient so as to allow meet of rotating palettes (6) by rounding on the inner surface of body (1) with pressure cover (11) and palette crescent cover (21) in harmony.

The invention described above and indicated in the figures attached hereto is considerably different from pumps and engines in the related art, and it is seen that a developed has been realized by rotation of palettes within the body (1) by rounding.
