WOBBLE PLATE TYPE COMPRESSOR WITH A VARIABLE DISPLACEMENT MECHANISM ABSTRACT OF THE DISCLOSURE A wobble plate type compressor with a variable displacement mecha- nism is described. A cylindrical member having a central hole and which supports the wobble plate at a variable angle of inclination is also described. The central hole has an annular edge portion on an inner surface which con- tacts the outer peripheral surface of the drive shaft to restrict radial move- ment of the cylindrical member while permitting the angle o-f inclination of the cylindrical member to be varied. The annular edge portion is a circular surface defined by the intersection of a first inclined surface of a first rightcircular cone that has an apex and a center point on the base and a second inclined surface of a second right circular cone that has an apex and a cen- ter point on the base. A central axis passes through the center point of the annular edge portion circle and the apex and center point of the base of both right circular cones. The first right circular cone opens toward one end of the cylindrical member and the second right circular cone opens toward the other end of the cylindrical member. Thus, the shape of the central hole is very simply and easily formed while the accuracy of the central hole is maintained.
