A sealed rotary compressor is provided which includes separate pump and gear chambers. Disposed within the pump chamber is a set of rotors operatively associated with a set of gears rotatably mounted within the gear chamber. A substantially pressure differential exists between the two chambers. Rotational power is applied directly to the rotors through a static seal rather than through the gears which are utilized primarily to transmit the dynamic load. The pump chamber is defined by two end plates with a surrounding thin-walled housing. Within the pump chamber are interior thin wall members with the rotary members disposed therebetween and defining inlet and outlet pockets operatively associated with a pump housing inlet and outlet means. The combination of pump and gear chambers are disposed within a separate pressure vessel whereby gas is introduced through the pressure vessel into the pump chamber and is expelled from the pump chamber into the interior of the pressure vessel from where it is expelled to a desired apparatus. The present invention is particulary suitable for applications with CO2 axial-flow lasers. |
