Compressor part to be formed with film and method of forming film on the same part

Abstract

A film forming method for a compressor and a part of the compressor to be formed with a film are disclosed. A paint container ( 36 ) is arranged above a rotary holding mechanism ( 34 ) with a swash plate ( 15 ) of the compressor mounted thereon. A lubrication paint ( 37 ) in the paint container ( 36 ) is dripped on the end surface ( 152 ) of the swash plate ( 15 ) through a dripping unit ( 38 ). The swash plate ( 15 ) is rotated at high speed by the operation of a motor (M) so that the surplus portion of the lubrication paint ( 37 ) on the end surface ( 152 ) is removed by centrifugal force. The lubrication paint ( 37 ) remaining on the end surface ( 152 ) with the surplus portion thereof removed by centrifugal force has a uniform film thickness.

1 . A film forming method, for a part of a compressor to be formed with a film by attaching a fluid paint to a film forming area, comprising the steps of: 
 attaching said fluid paint to said film forming area; and    removing by centrifugal force the surplus portion of said fluid paint attached to said film forming area thereby to form said film.    
     
     
         2 . A film forming method for a part of a compressor to be formed with a film according to    claim 1   , wherein said paint is a resin containing a solid lubricant.  
     
     
         3 . A film forming method for a part of a compressor to be formed with a film according to    claim 1   , comprising the step of forming a film by dripping and attaching said paint on said film forming area.  
     
     
         4 . A film forming method for a part of a compressor to be formed with a film according to    claim 2   , comprising the step of forming a film by dripping and attaching said paint on said film forming area.  
     
     
         5 . A film forming method for a part of a compressor to be formed with a film according    claim 1   , comprising the step of spreading said paint on the flat surface of said film forming area due to the centrifugal force.  
     
     
         6 . A part of a compressor to be formed with a film in a film forming area, wherein said film is formed according to the method described in any one of    claims 1    to    5   .  
     
     
         7 . A part of a compressor to be formed with a film according to    claim 6   , wherein said compressor is a swash plate compressor having at least a shoe interposed between a piston and a swash plate integrally rotated with a rotary shaft in such a manner that the shoe is in sliding contact with both said swash plate and said piston, the rotation of said swash plate is transmitted to said piston through said shoe thereby to reciprocate said piston, said part to be formed with a film is said swash plate, and the slide contact area of said swash plate in sliding contact with said shoe constitutes said film forming area.
