Problems solved by technology

[0015] However, the conventional variable displacement swash plate type compressor has a structure in which the swash plate is directly in contact with the drive shaft, so it cannot move smoothly on the slope
[0016] In addition, the swash plate moves obliquely relative to the drive shaft, which causes severe vibration of the contact surface and generates noise or even damage to the contact surface
[0017] Additionally, the guide pins may be lifted during operation, creating vibrating noise and reducing efficiency

Embodiment Construction

[0048] Hereinafter, preferred embodiments of the present invention will be described with reference to the corresponding drawings.

[0049] 2 to 8 show the structure of a variable displacement swash plate type compressor in which the swash plate can move smoothly in an inclined state.

[0050]As shown in the figure, the variable displacement swash plate compressor 1000 includes a cylinder 110 having a plurality of cylinder holes 110a, wherein the cylinder holes 110a are formed parallel and longitudinally along the inner peripheral surface of the cylinder, and constitute the outer parts of the compressor, one located at the cylinder 110 Front end and form the front housing 120 of the swash plate chamber 120a, a drive shaft 140 that is rotatably supported in the cylinder 110 and the front housing 120, and a drive shaft 140 that is located in the swash plate chamber 120a of the front housing 120 and is fixedly installed on the drive shaft 140 Ear plate 180 on the top, a rear casi...

Abstract

A variable displacement swash plate compressor with smooth movement characteristics is disclosed. The shaft sleeve (300) is movably inserted into the drive shaft (140) and engaged with the inner surface of the insertion hole (150a) of the swash plate (150). The inclined plate (150) is tilted and rotationally engaged with the sleeve (300); the first hook groove (182) is formed on the rear surface of the ear plate (180) opposite to the inclined plate (150), and the guide surface (183) is formed on On both sides of the first hook groove (182), a second hook groove (184) is formed inward along the guide surface (183); a hook-shaped protrusion (151) is formed on the inclined plate (150) opposite to the ear plate (180). ), which is engaged with the first hook groove (182), and the guide pin (152) protrudes from both sides of the hook-shaped projection (151), along the guide surface (183) on the ear plate (180) and the third The two hook grooves (184) move relatively.

Description

technical field [0001] The present invention relates to a variable-displacement swash-plate type compressor with smooth tilting movement characteristics, and more particularly, to a swash-plate type variable displacement swash-plate type compressor capable of moving smoothly in a tilted state without being lifted machine. Background technique [0002] The traditional inclined plate compressor widely used in automobile air conditioners includes a disc-shaped inclined plate with a certain inclination, which is fixedly installed on the drive shaft, and is driven by the drive shaft to rotate to transmit power. The piston is mounted on the outer periphery of the swash plate by inserting a shoe between the swash plate and the piston. Through the rotation of the swash plate, the piston reciprocates linearly in a plurality of cylindrical holes formed in the cylinder, thereby sucking, compressing and discharging cooling gas. [0003] Recently, a variable displacement inclined plate...
