ROTATION REGULATING STRUCTURE OF PISTON IN COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a rotation regulating structure of a piston in a compressor which can supply sufficient quantity of lubricating oil of a crank chamber between a piston side rotation regulating part and a housing side rotation regulating part. SOLUTION: In a rotation regulating structure which regulates rotation at around an axial line S of a piston 20 itself, a guide slope 45 is provided at a piston side rotation regulating part 41, and wedge effect is performed by means of a reciprocating motion of the piston 20 between the guide slope 45 and a housing side rotation regulating part 43 to thereby guide lubricating oil of a crank chamber 15 to the interval of the both rotation regulating parts 41, 43 therebetween.
