OPERATION METHOD OF PISTON VERTICAL HYBRID MACHINE OF DIMENSIONAL ACTION AND METHOD FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC F04B19/06 

FIELD: machine engineering.

SUBSTANCE: piston machine contains a cylinder 1, divided by the piston 2 into gas 3 and fluid chambers 4. They are connected to the gas and liquid source and consumer through the reverse suction 5 and 6 and discharge valves 7 and 8. The reverse self-operated liquid valve 9 is installed at the piston bottom 2 opposite to the suction valve 5 of the cavity 3, connected through the hole 10 with chamber 3 and through the channels 11 with chamber 4. The spring 12 of the valve 9, is leant through the glass 13 on the adjusting screw 14. During the compression and liquid discharge in the liquid chamber 4, due to the leakages of fluid through the piston seal, a layer of the liquid over the piston 2 in the gas chamber 3 is created, which is evacuated at the end of gas injection process into the liquid subpiston chamber. The liquid volume, exceeding the dead volume of the chamber 3 is left over the piston 2 by the end of the gas injection process. The excess liquid flows to the chamber 4 through the opened valve 9.

EFFECT: power efficiency of the gas chamber work cycle is improved, the hydraulic impact occurrence conditions are eliminated, the operating pressures range of the liquid chamber is expanded.
