Embodiment Construction

[0021] Refer below figure 1 and 2 A first preferred embodiment of the swash plate compressor according to the present invention will be described. figure 1 A longitudinal sectional view of a single-head piston type variable displacement swash plate compressor 10 is shown. figure 1 The left and right sides of the compressor 10 shown in FIG. 10 correspond to the front and rear sides of the compressor, respectively.

[0022] Such as figure 1 As shown, the compressor 10 includes a cylinder block 11 , a front casing 12 fixedly connected to the front end of the cylinder block 11 , and a rear casing 14 fixedly connected to the rear end of the cylinder block 11 through a valve plate assembly 13 . The cylinder block 11 , the front housing 12 and the rear housing 14 together form a housing assembly of the compressor 10 .

[0023] A crankcase 15 is formed between the cylinder block 11 and the front housing 12 in the housing assembly. A drive shaft 16 is rotatably supported at the ce...

Abstract

A swash plate compressor includes a housing that has a cylinder bore and rotatably supports a drive shaft. A swash plate is operatively coupled to the drive shaft for rotation therewith. A piston is accommodated in the cylinder bore for reciprocating movement. First and second spaced shoes are fitted to the piston on a side adjacent to the cylinder bore and on a side away from the cylinder bore, respectively, for coupling the piston to the swash plate. The rolling body is mounted on the swash plate through a bearing and in slide contact with the first shoe. A surface of the rolling body in slide contact with the first shoe or a surface of the first shoe in slide contact with the rolling body has a diamond-like carbon film. A surface of the rolling body in rolling contact with the bearing exposes a base material of the rolling body.

Description

technical field [0001] This invention relates generally to a swash plate compressor, and more particularly to a mechanism for converting rotation of the swash plate into reciprocating motion of the pistons. Background technique [0002] For example, Unexamined Japanese Patent Application Publication No. 8-28447 discloses a conventional variable displacement swash plate compressor for compressing refrigerant gas. According to this publication, the compressor has a single-headed piston 22 slidably accommodated in each cylinder bore 1 a, and a pair of spherical shoes 23A, 23B fitted to the neck of the single-headed piston 22 . The swash plate 15 has a boss portion formed on the back thereof, and a thrust bearing 20 is mounted to the boss portion via bearing races 20a, 20b on the front and rear sides of the bearing 20, respectively. The bearing race 20 a is in contact with the swash plate 15 . The swash plate 15 and the thrust bearing 20 are inserted between the shoes 23A, 23B...
