ABSTRACT:
The problem of space and weight limitations for liquid ring pumps and regenerative pumps in aerospace applications is solved by a pump having a housing defining a first chamber (22) and a second chamber (24) independent of the first chamber. An impeller (10) is rotatably mounted in the housing and includes impeller blades (16) successively movable through the first chamber for cooperation therewith to provide a liquid ring portion of the pump, and through the second chamber for cooperation therewith to provide a regenerative portion of the pump. An inlet (26) admits fluid to the first chamber. A first outlet (28) from the first chamber feeds the fluid to an inlet (32) of the second chamber for pressurization therein. An outlet (34) from the second chamber feeds the pressurized fluid for appropriate use, such as in a fuel pump system. A dual pump configuration also is contemplated with a pair of first chambers (22, 22a) and liquid ring portions of the pump, and a pair of second chambers (24, 24a) and regenerative portions of the pump. The fluid in the dual ring pump portions is fed to one of the liquid compressor portions and then to the other regenerative pump portion for doubling the effectiveness of the pump. All of this is accomplished by a unitary housing and a single impeller.
