Lubricating films are formed on end surfaces of a swash plate, respectively. The lubricating films make slide contact with shoes, respectively. The lubricating films are composed of a copper based material containing no lead, and solid lubricant other than lead is contained the copper based material. A good slide contact characteristic may be obtained while using no lead.

Component having slide contact area of compressor

A compressor includes pistons, each of which is coupled to a swash plate through a pair of shoes. The swash plate rotates integrally with a drive shaft. The shoes convert the rotation of the swash plate to the reciprocation of the piston. A lubricating coating made of copper-based material is formed on parts of the swash plate along which the shoes slide. The copper-based material includes silicon. The shoes smoothly slide on the swash plate, which is coated by the lubricating coating that uses minimum amount of lead.

Swash plate for compressor

A sliding member comprising at least one sliding layer including a solid lubricant and at least one thermosetting resin with which particles of the solid lubricant are held together, the solid lubricant containing 10-40 vol. % of polytetrafluoroethylene. A sliding device comprising: at least one first sliding member each including at least one sliding layer which includes a solid lubricant and at least one thermosetting resin with which particles of the solid lubricant are held together, the solid lubricant containing 10-40 vol. % of polytetrafluoroethylene; and at least one second sliding member plated with a nickel-based composition; and wherein the at least one first sliding member and the at least one second sliding member slide relative to each other.

Sliding member and sliding device

A method of producing a shoe for a swash plate type compressor, the shoe being disposed between a swash plate and a piston of the swash plate type compressor and formed of an aluminum alloy, the method comprising: a main forging step of forging a blank for producing the shoe into a roughly-shaped precursor shoe; a thermal refining step of thermally refining the roughly-shaped precursor shoe; and a size-adjustment forging step of forging the roughly-shaped precursor shoe which has been thermally refined, into a size-adjusted shoe.

Method of producing shoe for swash plate type compressor

A swash plate type variable displacement compressor has a housing, a drive shaft, a swash plate and a piston. The housing includes a cylinder block, a front housing, and a rear housing. The drive shaft is rotatably supported by the housing. The swash plate is connected to the drive shaft, and is integrally rotatable with the drive shaft and tiltable relative to the drive shaft. The piston engages with the swash plate through a pair of shoes. Rotation of the drive shaft is converted to reciprocation of the piston through the swash plate and the shoes, and the displacement of the compressor is adjusted by varying the inclination angle of the swash plate with respect to the axis of the drive shaft. The swash plate includes a base member made of copper series and a sliding layer coating a sliding surface of the base member with respect to the shoes.

Swash plate in swash plate type compressor

A shoe for use in a swash plate type compressor, interposed between a swash plate and a piston, has a base member and metal plating layer. The base member is made of aluminum alloy. The metal plating layer coats at least a part of surface of the base member. The thickness of the metal plating layer ranges from 20 &mgr;m to 150 &mgr;m.
