Abstract

[Problem to be Solved] To improve the adhesion resistance of a swash plate in a swash plate type compressor. [Means to Solve the Problem] Lubrication film made of a cured coating film composed of a binder resin containing 100% by weight of polyamideimide resin and 2 to 18% by weight of bisphenol-A epoxy resin, and a solid lubricant containing polytetrafluoroethylene and graphite is provided on the surface of the swash plate substrate.

Claims

exact text as granted — not AI-modified
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 an inclination angle or attached to the drive shaft via a connecting member with a variable inclination-angle and slidable 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 made of a cured coating film composed of a binder resin containing 100 parts by weight of polyamideimide resin and 2 to 18 parts by weight of bisphenol-A epoxy resin and a solid lubricant containing polytetrafluoroethylene and graphite is provided on a surface of a swash plate substrate. 
     
     
         2 . The swash plate type compressor according to  claim 1 , wherein surface roughness of the swash plate substrate in Rzjis is 8.0 to 13.0 micron-meters. 
     
     
         3 . The swash plate type compressor according to  claim 1 , wherein 40 to 70 parts by weight of polytetrafluoroethylene and 1 to 20 parts by weight of graphite against 100 parts by weight of the binder resin are contained in the composition for film formation. 
     
     
         4 . The swash plate type compressor according to  claim 2 , wherein 40 to 70 parts by weight of polytetrafluoroethylene and 1 to 20 parts by weight of graphite against 100 parts by weight of the binder resin are contained in the composition for film formation.
