Problems solved by technology

However, if the content of the fixed lubricant is increased, the solid lubricant will easily fall off from the sliding film, resulting in an increase in the wear depth of the sliding film

Embodiment Construction

[0052] Several embodiments of the invention will now be described with reference to the accompanying drawings. Similar or identical reference numerals denote similar or identical components in the drawings.

[0053] will refer to Figures 1 to 16 The first embodiment of the present invention is described.

[0054] Such as figure 1As shown, the variable displacement swash plate compressor includes a cylinder block 1 made of an aluminum-based alloy, a front housing 2 made of an aluminum-based alloy and fixed to the front end of the cylinder block 1, and a cylinder block made of an aluminum-based alloy. The rear casing 4 is fixed to the rear end of the cylinder block 1 through the valve mechanism 3, and the valve mechanism 3 includes a valve plate, an exhaust valve and a baffle. A crank chamber 2 a is defined between the cylinder block 1 and the front housing 2 . An air intake chamber 4 a and an exhaust chamber 4 b are defined in the rear case 4 . In this embodiment, the cyl...

Abstract

A compressor has a swash plate and shoes. Surfaces of the swash plate slides on flat surfaces of the shoes. A sliding film is formed on each of the swash plate surfaces. The sliding films are formed of a polyamide-imide resin that contains at least solid lubricant. The polyamide-amide resin has a glass transition temperature of 270 DEG C, a tensile strength at room temperature of 200 MPa, or more imide groups than amide groups. When a base portion of the swash plate is made of an aluminum-based metal, the sliding films are formed on the base portion with middle layers made of anodized aluminum in between.

Description

technical field [0001] The present invention relates to a compressor. Background technique [0002] Japanese laid-open patent application 2002-89437 discloses a compressor having a housing in which a plurality of cylinder bores, a crank chamber, a suction chamber and a discharge chamber are formed. The compressor is incorporated into a refrigeration circuit comprising an evaporator, a suction device and a condenser. Each cylinder bore of the compressor houses a corresponding piston and causes the piston to reciprocate. An external drive source such as a motor drives a drive shaft rotatably supported by the housing. The swash plate is supported on the drive shaft and rotates synchronously with the drive shaft. The swash plate is connected with the piston through multiple pairs of hemispherical shoes. A sliding film is formed on a surface of the swash plate which slides on the plane of the shoe. The sliding film is formed of a binder resin containing a solid lubricant suc...
