Variable displacement swash plate type compressor

Abstract

Provided is a variable displacement swash plate type compressor including: a lug plate fixed to a driving shaft; and a swash plate combined to the lug plate and whose tilt angle is varied according to rotatory motion, wherein the lug plate includes a protruding portion protruding towards the swash plate, and a rotatory power projection transmitting power for rotating the swash plate is formed at a leading end of the protruding portion through the swash plate. Accordingly, a varying operation between a maximum tilt angle and a minimum tilt angle of the swash plate and a rotatory power transmitting operation for rotating the swash plate are performed at different locations, thereby simultaneously improving the varying operation and the rotatory power transmitting operation of the swash plate.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0067081 filed with the Korean Intellectual Property Office on Jun. 22, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to variable displacement swash plate type (variable displacement swash plate type) compressors, and more particularly, to such a variable displacement swash plate type compressor that can The connecting structure of the discs improves both the inclination changing operation of the swash plate and the rotating operation of the lug plates. Background technique [0004] Generally, an air conditioner of a vehicle maintains a temperature inside the vehicle lower than an outdoor temperature by using a refrigerant, and includes a compressor, a condenser, and an evaporator, thereby forming a cycle of the refrigerant. [0005] This compressor compresses and...

Problems solved by technology

[0014] Here, due to the tilting motion of the swash plate 50 (in this tilting motion, the swash plate 50 repeatedly moves from the maximum inclination angle to the minimum inclination angle, and the rotational power transmission of the arm 52 for transmitting the rotational power of the ear plate 60 to the swash plate 50 operations are simultaneously performed at both sides of the protrusion 62), then not only the tilting movement and the turning power transmission operation cannot be performed smoothly, but also the rows are changed due to cracks caused by poor durability according to the load concentrated in the protrusion 62 Measuring swash plate compressors are also susceptible to damage
