Abstract (en)
[origin: WO02095226A1] The invention relates to a novel piston compressor whose return valves have a very good closure force and are extremely tight. The inlet return valve (15) is provided with a first sealing membrane (17) and the outlet return valve (30) is provided with a third sealing membrane. The two sealing membranes (17,32) are produced from an elastic polymer which has high disruptive strength, high temperature compatibility and memory properties.
