DEVICE FOR GAS COMPRESSION IN DOUBLE-ACTING CYLINDERS WITH HYDRAULIC CONTROL Russian patent published in 2020 - IPC F04B35/02 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in compressor equipment for high pressure gas injection. Device for gas compression in double-acting cylinders with hydraulic control comprises mechanism for conversion of energy of working fluid pressure into energy of compressed gas, which includes two or more pairs of double-acting cylinders with spring-loaded rods, in which rod chambers can perform as a function of hydraulic cylinders, and piston-type cylinders are pneumatic cylinders, and vice versa, reverse pneumatic valves connected to both low-pressure inlet port and high-pressure outlet port, hydraulic device to control mechanism of working fluid pressure energy conversion into compressed gas energy, including working fluid supply inlet port, hydraulically controlled two normally open and three normally closed two-position two-way hydraulic control valves, hydraulic reducing adjustable and check valves, connecting and drain pipelines, hydraulic tank.

EFFECT: such design of the device allows simplifying its design and reducing metal consumption.
