Abstract
In a swash plate type compressor having a shoe interposed between a swash plate and a concave surface of a piston, the concave surface has a first and a second spherical surface which are adjacent to and offset from each other to make a slight step extending along the concave surface. The shoe has a spherically convex surface received in the concave surface. In a condition where the spherically convex surface is received in the concave surface, the slight step serves to cause a small gap between the spherically convex surface and a part of the first spherical surface. When the swash plate is rotated together with a rotary shaft, the shoe converts a rotation of the swash plate into a reciprocating motion of the piston.
