A swash plate type compressor that provides long lasting high lubricating performance to the sliding contact surfaces of a swash plate and shoes. The surface of the swash plate or the shoes on which the swash plate comes in sliding contact with the shoes is provided with an alloy plating layer, in which tin is the main component, as a surface treating layer. A coating layer, in which molybdenum disulfide is the main component, is formed as a solid lubricant layer on the foregoing plating layer. Preferably, the swash plate is made of aluminum or an aluminum alloy, and its surface is provided with the plating layer and the coating layer. More preferably, the coating layer contains graphite.

Reciprocating compressor

A swash plate type compressor is provided with a surface coating layer on the surface of a swash plate. The surface coating layer acts to prevent the frictional resistance which leads to seizure conventionally occurring by the direct contact of the shoes and the swash plate body. The swash plate body is produced from aluminum or aluminum alloy and the surface coating layer is made of tin and at least one metal selected from the group consisting of copper, nickel, zinc, lead and indium.

A shoe incorporated into a swash plate type compressor as a drive force transmitting element intervened between a rotatable swash plate and a reciprocal piston has a first member made of a seizure-resistant material such as ceramic and hard metal, and has a flattened contact face in slidable contact with the swash plate, and a second member made of less seizure-resistant material but easily machined and having a spherical bearing face slidably engaged with the piston, the first and second members being joined together to form a unitary element.
