摘要：
A piston reciprocating type compressor has a passage structure for connecting a crank chamber to a discharge chamber and/or a suction chamber. A gas bleeding passage connects the crank chamber to the suction chamber. The gas compressed by the piston in the cylinder bore is leaked to the crank chamber causing the pressure raise in the crank chamber. The bleeding passage release the excessive pressure in the crank chamber to the suction chamber. The bleeding passage is partially deformed by a notch formed in a gasket. The notch has a smaller sectional area than the rest of the bleeding passage, regulating the pressure transmitted from the crank chamber to the suction chamber.
