Problems solved by technology

[0003] However, this coupling mechanism cannot precisely control the size of the piston clearance (referring to the minimum gap between the piston end face and the cylinder body plane) in the compressor, resulting in low volumetric efficiency of the compressor and reduced performance of the compressor.

Embodiment Construction

[0011] Such as Figure 1-3 As shown, the present invention is used in the variable displacement swash plate compressor. The compressor has a cylinder block 8, a front housing 7, a drive shaft 5 and a drive disc 1, a rear housing part 10, a swash plate 4, a guide arm 3, a sliding shoe 12, and a piston 13;

[0012] The front housing 7 closes the front end of the cylinder block 8, and forms a crank cavity 14 inside the cylinder block 8, and has several piston holes 11 arranged side by side to form the outer contour of the compressor;

[0013] The drive shaft 5 is supported by the cylinder block 8 and the front housing 7, and has an axis and can rotate around the axis;

[0014] The drive disc 1 is fixed on the drive shaft in the crank chamber 14, and the drive disc 1 is provided with two guide holes (or guide grooves) 2;

[0015] The rear housing 10 has an air suction chamber 15 and an exhaust chamber 16 and closes the rear end of the cylinder block, and the rear housing 10 is e...

Abstract

A coupling mechanism of displacement-variable swashplate type compressor is composed of the drive disk and the swash plate, which are mounted to the drive shaft of compressor. Two stright or curved guide arms are mounted on said swash plate. Said drive disk has two shaped guide holes matched with said guide arms. Its advantages are high guide accuracy, and low cost.

Description

(1) Technical field [0001] The present invention relates to a variable-displacement swash-plate rotary compressor for a vehicle air-conditioning unit, and more particularly to a coupling mechanism in the compressor. (2) Background technology [0002] Such as Figure 4 As shown, the coupling mechanism of the existing variable displacement swash plate compressor includes a drive disc 17 and a swash plate 21 installed on the drive shaft. Two linear guide holes 18 are opened on the driving disc 17, and two guide pins 19 with spherical heads are installed on the swash plate 21. Part slides in the hole 18, thereby changing the angular size of the swash plate 21. [0003] However, this coupling mechanism cannot precisely control the size of the piston clearance (referring to the minimum clearance between the piston end surface and the cylinder body plane) in the compressor, resulting in low volumetric efficiency of the compressor and reduced performance of the compressor. (3) Co...
