CAPACITY CONTROL STRUCTURE FOR VARIABLE DISPLACEMENT COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To prevent the generation of abnormal noises and breakage of a capacity resetting spring while suppressing enlarging of a compressor. SOLUTION: A circlip 26 is fitted to a rotary shaft 18 between a swash plate 20 which is tiltably supported and a radial bearing 52 which rotatably supports the rotary shaft 18. One end 271 of a capacity resetting spring 27 is fixed to an end face of the circlip 26 as an unmovable end. Natural length of the capacity resetting spring 27 is shorter than spacing between the swash plate 20 at its maximum tilting position and the circlip 26. The swash plate 20 is brought into contact with a free end 272 of the capacity resetting spring 27 during decreasing process of the tilting angle from the maximum tilting position.
