ABSTRACT:
A swash plate type compressor is disclosed which is intended to prevent a hemispherical shoe, provided between the piston and the swash plate, from being spun on slat surface of the swash plate during operation of the compressor. In the preferred embodiment of the invention, the swash plate is formed with a step and the shoe with a cut portion engageable with the step so that the shoe is prevented from being spun on the slant surface of the swash plate which provides a turning moment to the shoe. The step is formed by an annular projection having an annular wall portion defining the inner limit of the slant surface area of the swash plate with which the flat face of the hemispherical shoe is kept in sliding contact, and the cut portion of the shoe has a curved surface conforming to the curvature of the annular wall portion. The shoe is located with its cut portion slidably contactable with the annular wall portion.
