ABSTRACT:
A reciprocating compressor includes reciprocating pistons moved by a swash plate. A housing member is attached to one end of the cylinder block via a valve plate. A discharge chamber is formed in the peripheral region in the housing member, and a suction chamber and an oil chamber are formed in the central region in the housing member in an axially juxtaposed relationship. Alternatively, a suction chamber is formed in the peripheral region, and a discharge chamber and an oil chamber are formed in the central region. The oil chamber is connected to the suction chamber by an oil return passage. A centrifugal type or collision type oil separating device is arranged in the discharge chamber above the oil chamber in the housing member.
