ABSTRACT:
A piston vacuum pump includes a housing (40) which is extruded from aluminum to form a bore (42) for movably receiving a piston (44). The piston is made from a plastic material to define a sealing interface with the aluminum housing in the absence of additional sealing rings and lubricants. The extruded housing is also provided with an opening (64) to receive an input member (90) and to provide for fluid communication through the pump.
