SWASH PLATE TYPE COMPRESSOR

摘要

[Problem] In a swash plate of a swash plate type compressor, adhesion resistance of the swash plate will be greatly improved as compared with that achieved in the prior art by optimizing the average aspect ratio and the average particle size of the fluororesin particles contained in a lubrication film provided on the swash plate. [Solution] In a swash plate of a swash plate type compressor, a lubrication film composed of a binder resin, the fluororesin particles having an average aspect ratio of 1 to 1.5 and an average particle size of 7 to 13 micron-meters, and the graphite is provided at a sliding portion against a shoe of the swash plate.

1. A swash plate type compressor including a drive shaft rotatably disposed in a housing, a swash plate fixed directly to the drive shaft with a tilt angle or attached to the drive shaft via a connecting member with a variable tilt angle and rotate integrally with the drive shaft, a shoe disposed between the swash plate and a piston, and the piston reciprocating in a cylinder bore; and the swash plate type compressor converts rotational movement of the swash plate into reciprocating movement of the piston to compress a refrigerant; wherein a lubrication film composed of a binder resin, fluororesin particles having an average aspect ratio of 1 to 1.5 and an average particle size of 7 to 13 micron-meters, and the graphite is provided at a sliding portion against the shoe of the swash plate.
