VOLUMETRIC ACTION ROTARY-PISTON HYBRID MACHINE Russian patent published in 2018 - IPC F04B23/10 F01B21/00 F04C18/50 

FIELD: machine engineering.

SUBSTANCE: machine consists of a body 1 with cylinders 2, 3, with rotors 10, 11, with projections 12, 13 which are driven by shafts 4, 6, synchronized by toothing 7, 8, 9 and a rotor 17 with recess 18. In the cylinders there are suction ports 27, 29 and pressure valves 29, 30. The shaft 4 has a crank 33 with rods 34, 46, on which the pistons 35, 47 are pivotally mounted in cylinders 32, 36 with valves 37, 40, 48, 49. In the cylinder 36 there are bypass channels 43 and 45. Channel 43 has a spool 44 protruding into the cavity of the cylinder 36. The suction port 27 and the valve 37 are connected by a suction line 39 to a source of liquid 38. The valves 29, 40 are connected by a pressure line 41 to consumer of liquid 42. The valve 30 is connected by the pressure line 50 to heat exchanger 51 which is connected to the cylinder 32 via the valve 48. The valve 49 is connected by the pressure line 52 to gas consumer 53.

EFFECT: increased specific power of the machine, extended field of application, higher specific power, reduced material usage and reduced cost of compressed gas and liquid under pressure.
