PISTON COMPRESSOR WITH INDEPENDENT COOLING OF CYLINDER Russian patent published in 2016 - IPC F04B39/06 

FIELD: machine building.

SUBSTANCE: invention relates to compressor building industry and can be used in piston compressors with independent liquid cooling of cylinder-piston group. Compressor comprises cylinder 1 with piston 2 with formation of compression chamber 4, suction valve 6, pressure valve 11. Cylinder 1 comprises jacket 15 of cooling connected with cooling liquid source 16 in the form of float chamber 17 with spring-loaded hollow float 19 with rod 20 with ledges 21 and 22 impacting on movable element 23 of slide valve 24. Movable element 23 has two grooves 26 and 27 for retainers 28. One output 29 of slide valve 24 is connected with the atmosphere, and the other one 30 - with chamber 4 via channel 31 and valve 43. Chamber 17 is connected by channel 33 with jacket 15 of cooling and with heat exchanger 34 by channels 38 and 39, wherein the groups of differently directed hydro-diodes 40 and 41 are installed.

EFFECT: adequate completely independent cooling of the cylinder with minimum costs of energy is achieved, increase in efficiency of compressor while reducing its dimensions and weight, possibility to create movable compressors with efficient liquid cooling is provided.
