METHOD OF PISTON COMPRESSOR OPERATION AND DEVICE FOR IMPLEMENTATION THEREOF (EMBODIMENTS) Russian patent published in 2024 - IPC F04B39/06 F04B53/10 

FIELD: machine building.

SUBSTANCE: group of inventions relates to piston-type positive displacement machines and can be used in designing compressors capable of operating in extreme conditions. Method of piston compressor operation consists in alternate suction and discharge of gas and liquid passing through suction and discharge valves 28 and 29, having flow section in the form of slots between seats 41 and 44, respectively, and shutoff elements 42 and 43, respectively, and connecting working chamber 2 of cylinder 1 with gas and liquid lines. Liquid injection is carried out through a slot having a larger flow section due to increase in the height of shutoff element 43 or increase in the slot diameter than during gas injection.

EFFECT: invention is aimed at improving the reliability and efficiency of the compressor.
