Abstract
A swash plate type compressor having a compressor casing accommodating a swash plate operated compressing mechanism compressing a refrigerant gas supplied from a suction side of a refrigerant circulating circuit and discharging a compressed refrigerant gas into a discharge side of the circuit, and an internal lubricating system for lubricating movable elements of the swash plate operated compressing mechanism by using a lubricating oil reserved in a swash plate chamber and an oil sump provided in the bottom of the compressor casing, the compressor casing having a refrigerant and lubricant separating chamber for separating a lubricant component from a lubricant suspended refrigerant gas generated in the swash plate chamber by a high pressure blow-by refrigerant gas and a mist of the lubricant oil when the gas flows from the swash plate chamber toward the suction side of the refrigerant gas circulating circuit, and a refrigerant gas evacuation passageway extended from the refrigerant and lubricant separating chamber to the suction side of the refrigerant circulating circuit to permit an evacuation of the refrigerant gas after the lubricant separation.
