FIELD: energy.
SUBSTANCE: invention relates to power engineering and compressor industry and can be used in designing piston compressors. Piston machine comprises cylinder 1 with piston 2 to form working volume 4, valve box 5 with suction cavity 6, suction line 7, suction valve 8, discharge cavity 11, pressure line 12, pressure valve 13. Cooling jacket 14 is connected with fluid pressure source, in form of arranged in valve box 5 cavity 15 with flexible membrane 16. Cavity 15 connected via channels 17 and 18, made in the form of heat exchangers, with jacket 14 via check valves 19 and 20. Reverse side of membrane 16 is covered by gas chamber 21.
EFFECT: reduced total weight and overall dimensions of compressor plant, enabling creation of a mobile structure, reduction of specific costs for gas compression.
