Swash plate compressor

Abstract

A swash plate compressor according to the present invention includes a first slide layer formed between a swash plate and shoes; and a second slide layer formed between cylinder bores and pistons. The first slide layer and the second slide layer each contain binder resin and solid lubricant. The first slide layer has a smaller contact angle of lubricating oil than the second slide layer.

1 .- 4 . (canceled) 
     
     
         5 . A swash plate compressor comprising:
 a housing that includes a swash-plate chamber and a plurality of cylinder bores;   a drive shaft that is supported by the housing and is rotatable within the swash-plate chamber;   a swash plate that is disposed within the swash-plate chamber and is synchronously rotatable with the drive shaft;   shoes that slide on the swash plate;   a piston that is allowed by the shoes to make strokes that depend on an inclination angle of the swash plate to reciprocate within the corresponding cylinder bore to compress refrigerant that contains lubricating oil;   a first slide layer formed between the swash plate and the shoes; and   a second slide layer formed between the cylinder bores and the piston, wherein   the first slide layer and the second slide layer each contain binder resin and solid lubricant,   the solid lubricant of the first slide layer contains ultra high molecular weight polyethylene, and the solid lubricant of the second slide layer contains fluorine resin, and   the first slide layer has a smaller contact angle of the lubricating oil than the second slide layer.   
     
     
         6 . The swash plate compressor according to  claim 5 , wherein the swash-plate chamber directly communicates with an evaporator. 
     
     
         7 . The swash plate compressor according to  claim 6 , further comprising:
 a linkage that is disposed within the swash-plate chamber and allows a change in the inclination angle of the swash plate; and   an actuator that is disposed within the swash-plate chamber and changes the inclination angle of the swash plate, wherein   the actuator includes:
 a partition body that is rotatable with the drive shaft within the swash-plate chamber; 
 a movable body that is rotatable with the drive shaft within the swash-plate chamber and moves with respect to the partition body in an axis direction of the drive shaft to change the inclination angle; 
 a control pressure chamber that is defined by the partition body and the movable body and has a pressure within the control pressure chamber that moves the movable body; and 
 a control mechanism that controls the pressure within the control pressure chamber.
