ABSTRACT:
The present invention is a compressor using an Oldham-type assembly functioning as a piston to provide a compressing pump. An orbiting plate is eccentrically mounted on the crankshaft, and a compressing pump body is fixed within the interior of the housing. An Oldham piston is disposed within the compressing pump and has tabs which engage slots on the orbiting plate. The side walls of the pump body prevent movement of the Oldham piston in a first direction so that the orbiting of the plate causes the piston to reciprocate in a second, orthogonal direction. Suction valves on the piston control entry of refrigerant into the compressing pump, and discharging valves control refrigerant discharge.
