ROTARY HYBRID MACHINE OF VOLUMETRIC ACTION Russian patent published in 2018 - IPC F04C2/356 F04C18/356 

FIELD: machine building.

SUBSTANCE: invention relates to hybrid machines of volumetric action. Machine comprises cylinder (1), rotor (5) with two plates (7) dividing cylinder (1) into two cavities - compressor one (9) with suction window (11) and discharge valve (12) and pump one (10) with suction valve (13) and discharge valve (14). Valve (13) is connected to hydraulic tank (50), and valve (14) with spool (17) and further with spool (47) and through it - with the liquid consumer. Window (11) is connected to the gas source, and valve (12) - with spool (37) and further - with gas receiver (28) and through it - with the gas consumer. Control of spool (17) is performed by the pressure difference between the gas pressure, which is fed to it via channel (18), and the liquid pressure, which is fed to it via channel (15). Spool (37) is controlled by the difference in the forces between spring (42) and the force from the pressure in receiver (28). Control of spool (47) is performed manually using handle (58). Operation of spool (17) ensures the supply of a liquid or a gas to cavity (6). Operation of spools (37) and (47) allows the machine to operate in the "pump", "pump-compressor" and "compressor" modes with the minimal operator involvement.

EFFECT: invention is aimed at simplifying the control of the machine and reducing the probability of an error in the control.
