<p>PURPOSE: To provide a swash plate type compressor capable of ensuring sufficient lubrication for restraining occurrence of an abnormal sound or wear, and properly and smoothly regulating rotation of a piston. CONSTITUTION: A detent section 82 having circular arc projected surface 82a with a larger radius of curvature R1 than a piston head radius Rp is formed on the external surface of an engagement section 23b engaged with a swash plate via a piston shoe. Also, the internal surface of a casing 12 faced to the detent section 82 is provided with a recess section 83 having circular arc recess surface 83a with a larger inner radius of curvature R2 than the piston head radius Rp at the prescribed distance L from the projected surface 82a of the section 82. In addition, an axially extended oil groove 83b is formed in the neighborhood of the peripheral center of the section 83.</p> |
