Abstract
The sliding characteristics of the sliding portions, where components slide on each other, are improved and the work of coating forming thereof is simplified. DLC coatings (43) and (44) are formed on a front surface (39) and a rear surface (40) of a swash plate (22) by a CVD method or a PVD method. Therefore, the sliding characteristics of the sliding portion (47) between the swash plate (22) and shoes (27) and (28) are improved and abrasion or seizure occurs less frequently on the surface of the swash plate (22) and flat surfaces (35) and (36) of the shoes (27) and (28).
Claims8
A swash plate type compressor comprising a swash plate assembled so as to enable a rotational motion together with a drive shaft, at least a pair of shoes connected to the swash plate, and a piston connected to the swash plate via the shoes, wherein
- an amorphous hard carbon coating is formed on at least one of the sliding portions where components of the compressor slide on each other during the operation of the compressor.
