Swash plate of swash plate type compressor

Abstract

A swash plate ( 15 ) of a swash plate type compressor includes a slide-contact film ( 32, 33 ) having a metal layer, which is formed on a slide-contact surface ( 152, 153 ), which slide-contacts shoes ( 18 ), through sintering, and a resin layer ( 322, 332 ), which is formed on the metal layer. By using the metal layer, which is formed through sintering, the bonding of the resin layer and the metal layer is guaranteed, deficiencies such as cracking of a slide film and seizure are prevented, and the slide-contact characteristic relative to the shoes is improved.

1 . A swash plate ( 15 ) of a swash plate type compressor that transmits the rotating force of the swash plate, which rotates integrally with a rotary shaft ( 13 ), to a piston ( 17 ) by means of a shoe ( 18 ) to reciprocally move the piston, wherein the swash plate rotates while slide-contact occurs between the shoe and a slide-contact surface ( 152 ,  153 ), the swash plate comprising: 
 a slide-contact film including a metal layer ( 321 ,  331 ), which is formed on the slide-contact surface of the swash plate through sintering, and a resin layer ( 322 ,  332 ) or a plating layer, which is formed on the metal layer.    
     
     
         2 . The swash plate according to  claim 1 , wherein the metal layer is made of a copper material or an aluminum material.  
     
     
         3 . The swash plate according to  claim 1  or  2 , wherein the resin layer or the plating layer includes a solid lubricant.  
     
     
         4 . The swash plate according to any one of  claims 1  to  3 , wherein the metal layer has a surface that is not ground, and the resin layer or the plating layer is formed on the surface.  
     
     
         5 . The swash plate according to any one of  claims 1  to  4 , wherein the swash plate is made of a steel material.  
     
     
         6 . A swash plate type compressor including: 
 a rotary shaft ( 13 );    a swash plate ( 15 ) rotated integrally with the rotary shaft;    a shoe ( 18 ) that slidably contacts a slide-contact surface of the swash plate ( 15 ) when the swash plate rotates; and    a piston ( 17 ) connected to swash plate by means of the shoe, the swash plate comprising:    a slide-contact film including a metal layer ( 321 ,  331 ), which is formed on the slide-contact surface of the swash plate through sintering, and a resin layer ( 322 ,  332 ) or a plating layer, which is formed on the metal layer.    
     
     
         7 . The swash plate type compressor according to  claim 6 , wherein the metal layer is made of a copper material or an aluminum material.  
     
     
         8 . The swash plate type compressor according to  claim 6  or  7 , wherein the resin layer or the plating layer includes a solid lubricant.
