<p>Compressor having a single cylinder (15012) with an enclosed end defining a compression space, with a piston (15002,15004) reciprocating in said single cylinder, comprising:
a plurality of gas flow paths (15008) from said compression space to a discharge space,
a self operating valve (15020;17008) in each said 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 (17006),
each said valve and spring being part of a single unitary planar valve member (15020;17002).</p> |
