Abstract
Difficulties in pumping mixtures of gases and liquids are avoided in a rotary machine which both pumps and separates the mixture and which includes a generally tubular, elongated pump housing 10 having a suction inlet 22 at one end, a first outlet 32 for gas at the other end, and a second outlet 58 for liquid intermediate the ends but in close adjacency to the outlet 32. The first outlet 32 is primarily axially directed and the second outlet 58 is primarily radially directed. An elongated rotor 30 is disposed within the housing and is disposed between the ends. The rotor 30 has a length to diameter ratio substantially in excess of one. A plurality of generally axially elongated, radially extending vanes 62 are carried by the rotor 30 and the second outlet 58 is surrounded by a volute 40.
