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

Embodiment Construction

[0033] In the following, reference will be made to Figure 2 to Figure 7 One or more exemplary embodiments of the invention are described more fully.

[0034] like figure 2 As shown, the variable displacement swash plate compressor includes: a casing 100; a cylinder block 200 installed in the casing 100 and including a plurality of cylinder holes 210; a drive shaft 300 rotatably supported by the cylinder block 200; fixed to lug plate 400 on drive shaft 300 ; swash plate 500 whose inclination angle changes while being rotated by lug plate 400 ;

[0035] Since the housing 100, the cylinder block 200, the drive shaft 300 and the piston 600 are compared with the reference Figure 1A Those components of the illustrated variable displacement swash plate compressor are the same or similar, so their details will not be repeated, and only the different components will be described here.

[0036] like Figure 3 to Figure 7 As mentioned above, the ear plate 400 includes a protrusion ...

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...
