A rotary compressor including an orbiting piston is disposed within a cylinder bore. A drive shaft with an attached eccentric causes the piston to orbit within the cylinder block. Rotation of the piston is prevented by a pin radially disposed on the piston and slidably engaged through a recess in the cylinder bore. A plastic pinion is interfit about the radially outward end of the pin and disposed within the recess to prevent piston rotation and reduce re-expansion volume.
