ABSTRACT:
An improvement of a piston type compressor is disclosed. The compressor has a cylinder block that includes a plurality of cylinder bores and a plurality of suction passages. Each of the suction passages extends through the cylinder block to connect a crank chamber with a suction chamber. The suction chamber is connected with the cylinder bores via a plurality of suction ports located in association with the cylinder bores. Each cylinder bore accommodating a piston that moves therein to circulate gas between the compressor and an external gas circuit. The gas introduced into the crank chamber from the external gas circuit is supplied to the suction chamber through each suction passage and is supplied from the suction chamber to each cylinder bore through an associated suction port. The suction passages are smaller in number than the cylinder bores. The suction ports are disposed in the vicinity of an opening of the suction passages.
