ABSTRACT:
A swash plate type compressor having axially spaced inlet chambers and outlet chambers located on the side of angularly spaced pistons having each side thereof pump chambers which are connected to inlet chamber when the medium is introduced into the pump chambers, and are connected to the outlet chamber when the medium is removed to the outlet chambers. A swash plate chamber is arranged inside the cylinder block and cooperates with the pistons via respective shoes for reciprocating the pistons in the respective cylinder bores. An inlet of the fluid to be compressed is opened to the swash plate chamber at a circumferential position along the inner wall of the swash plate chamber. Communication passageways for connection of the swash plate chamber with the inlet chambers are arranged on position spaced farthest from the inlet port. The flow of the lubrication oil contained in the gas to be compressed is generated inside the swash plate chamber and comes into contact with all of the shoes, to lubricate same, before being introduced into the communication passageway from the swash plate chamber.
