Swash Plate Compressor

摘要

A swash plate compressor 100 includes a swash plate 111 that rotates with a drive shaft 110, a pair of shoes 137a and 137b placed to sandwich a portion of the swash plate 111 close to a periphery of the swash plate 111, and a piston 136 connected to the swash plate 111 via the pair of shoes 137a and 137b. The piston 136 reciprocates in a cylinder bore 101 a as the swash plate 111 rotates due to the rotation of the drive shaft 110. In the swash plate compressor 100, a zinc phosphate film is formed on each portion of the piston 136 at which the corresponding shoe 137a, 137b is in sliding contact. This reduces occurrence of galling or seizing at the sliding contact portions between the piston 136 and the shoes 137a and 137b.
