ABSTRACT:
A variable capacity swash plate type compressor having a hinge unit having a support arm protruding from a back side of a rotor, and a guide pin having one end thereof fixed onto a rotatable swash plate. The support arm has guide holes or guide surfaces which are parallel with a plane passing through a central axis "O" of a drive shaft and the top dead center position of the swash plate, the holes extending in a direction in which the holes approach the drive shaft from the outer edge of the rotor. Sections taken so as to be perpendicular to the center lines of the holes (guide surfaces) can be circular. A spherical element interacting with the guide holes is arranged at the end of the guide pin away from the rotatable swash plate. Thus, the spherical element of the guide pin interacts with the guide holes so that the suction force, compressive reaction force and torque are sustained on a line.
