Swash plate type compressor in which lubricating oil is effectively supplied to a shoe mechanism interposed between a piston and a swash plate

摘要

In a swash plate type compressor in which a shoe mechanism (23a and 23b) is slidably interposed between a swash plate (21) and a piston (22) to convert a rotating motion of the swash plate to a reciprocating motion of the piston, lubricating oil is effectively supplied together with a blowby gas to the shoe mechanism. As a result, the lubricating oil favorably lubricates a sliding portion which is between the shoe mechanism and each of the swash plate and the piston. The piston is inserted in a cylinder bore (1) of a cylinder block (2) to have a sealed gap around the piston. When the swash plate is rotatably driven, the piston is reciprocated through the shoe mechanism to compress a gaseous fluid including the lubricating oil. A part of the gaseous fluid passes as the blowby gas through the sealed gap during the reciprocation motion of the piston.
