Abstract
A variable displacement swash plate type compressor has a plurality of cylinders circumferentially arranged in a casing thereof. It includes a device for achieving a smooth axial movement of each piston in the cylinder while suppressing a rotational movement of the piston about an axis thereof. This device includes a cylindrical piston rod that extends from an eccentric portion of a piston head of each piston and a supporting plate tightly installed in the casing. The supporting plate has a circular opening through which the piston rod of each piston slidably passes.
