Piston compressor

摘要

A compressor comprising a cylinder (1) with an axially reciprocating piston (5) which compresses gas in the cylinder. At least two circumferential rows of flat fan spray nozzles (10) spray water into the cylinder during compression. Each nozzle is arranged such that the spray is in a plane substantially parallel to the axis (4) of the cylinder and is directed towards a central region of the cylinder.
