VARIABLE CAPACITY SWASH PLATE TYPE COMPRESSOR

摘要

A variable capacity swash plate type compressor comprising a swash plate 10 fixed to a shaft to incline freely and rotating integrally with the shaft, and a piston coupled with the swash plate 10 through a pair of shoes 60, 61 disposed to hold the swash plate 10 between wherein the stroke of the piston depends on the inclination angle of the swash plate 10. An annular groove 10c is made in the central region of the front sliding face 10a of the swash plate 10 touching the planar part 60a of one shoe 60. Contact area with the planar part 60a of one shoe 60 is maximized when the inclination angle of the swash plate 10 is largest and minimized when the inclination angle of the swash plate 10 is smallest.
