ABSTRACT:
A reciprocating piston type compressor comprises a cylinder block assembly, a drive shaft rotating together with a swash plate, a plurality of cylinder bores, a plurality of reciprocating pistons fitted within the cylinder bores, front and rear valve plates, front and rear suction and discharge valves, and front and rear housings. The front housing has a suction chamber for a refrigerant gas to be compressed and a discharge chamber for the compressed refrigerant gas in response to reciprocation of the pistons. The rear housing has a suction chamber for a refrigerant gas to be compressed, a discharge chamber for the compressed refrigerant gas, and an outlet chamber for delivering the compressed refrigerant gas carried therein from the discharge chamber of the front housing via a discharge passageway formed in the cylinder block assembly toward an external climate control system. A discharge conduit is formed in the discharge chamber of the rear housing to be orthogonally communicated with the outlet chamber. A sum of volumes of the discharge chamber of the front housing and the discharge passageway is the same as a sum of volumes of the discharge chamber of the rear housing and the discharge conduit. The discharge conduit extends to about half of the distance between a point on an interior surface of an inner wall of the rear hosusing and an opposite point on the interior surface of the inner wall.
