Compressor improvements

摘要

A compressor having a single cylinder with an enclosed end defining a compression space, with a piston reciprocating in the single cylinder, comprising a plurality of gas flow paths from the compression space to a discharge space, a self operating valve in each gases flow path, opening under the influence of the prevailing pressure differential across the valve, and being biased to a closed condition by a spring, each of the valves and springs being part of a single unitary planar valve member.
