PISTON DOUBLE-CYLINDER COMPRESSOR WITH LIQUID JACKET COOLING Russian patent published in 2018 - IPC F04B39/06 

FIELD: machine engineering.

SUBSTANCE: invention can be used for designing piston compressors with increased economy due to autonomous power-saving cooling system of the cylinder-piston group. The compressor consists of cylinders 1, 2 with a cooling jacket 14, pistons 15, 16, which are driven by a crankshaft 19 through connecting rods 17, 18. Gas is sucked into cavities 7, 8 of cylinders 1, 2 through suction line 12 the suction cavity 9 common for cylinders, and the return self-acting valves 3, 4, compressed and delivered to the consumer via the check self-acting valves 5, 6, pressure cavities 10,11 and pressure line 13. The pressure jacket 14 is connected via heat exchangers 28, 29 and check valves 26, 27 with the sealed tank 24 connected by channel 25 to cavity 9, and a through channel 30 with a tank 1 communicating with atmosphere by the opening 32.

EFFECT: consumption efficiency of the compressor is increased without additional energy costs.
