Title:
VARIABLE DISPLACEMENT SWASH PLATE TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2001/006124
Kind Code:
A1
Abstract:
A variable displacement swash plate type compressor, comprising a thrust flange (40) rotated integrally with a shaft (5), a swash plate (10) connected to the thrust flange (40) through a link mechanism (41), and a piston (7) which is connected to the swash plate (10) through shoes (60, 61) rotated on the sliding surfaces (10a, 10b) of the swash plate (10) relatively to each other, and performs a linear reciprocating motion in a cylinder bore (6) as the swash plate (10) is rotated, wherein carbon dioxide is used as a refrigerant, an annular height different part (10e) is formed only on the rear side sliding surface (10a) of the swash plate (10), and a plurality of needle rollers (52) and a race (53) rotatably holding these needle rollers (52) are disposed between the height different part (10e) and the shoe (60), whereby the tilt angle of the swash plate (10) varies according to a variation in pressure inside a crank case (8) in which the swash plate (10) is stored and the amount of stroke of the piston (7) varies accordingly.
