ABSTRACT:
A swash plate type compressor having a plurality of double-headed pistons reciprocating in axially extending cylinder bores of a cylinder block unit for compressing refrigerant gas, in which refrigerant gas returning from a refrigerating circuit is initially introduced into a swash plate chamber enclosed by a pair of axially opposed planar walls and a substantially cylindrical wall of the cylinder block unit, and is circularly flown along a pair of circular refrigerant passageways formed in both planar walls of the swash plate chamber before being drawn into the cylinder bores so that a circularly flowing refrigerant gas lubricates moving elements, such as shoes and radial and thrust bearings, of the compressor.
