This patent describes a sealed rotary compressor for circulating and recirculating gas through a laser, comprising: an enclosed pump chamber including inlet and outlet means and defined by first and second end plates and a surrounding sheet metal wall member; inner and outer sheet metal pocket wall members; each of the end plates having a groove formed in a pump chamber interior surface adapted to receive and retain the sheet metal pocket wall members defining inlet and outlet means; rotor members rotatably supported in the pump chamber and disposed between the pocket wall members; an enclosed gear housing defined by the second end plate and enclosing wall members; members adapted to provide a substantially zero-pressure differential between the pump chamber and the gear chamber; gear members rotatably supported in the gear housing and operatively associated with the rotor members, the gear members providing synchronized movement of the rotor members; and means for rigidly spacing and supporting the end plates and preventing rotational movement of the sheet metal pocket wall members.
