Abstract
The present invention provides an improved fluid pump that combines a liquid metal MHD pump with a plurality of fluid flow valves. The pump comprises a suction and pumping assembly, the suction and pumping assembly in turn comprising a first vertical chamber and a second vertical chamber connected using an intermediate horizontal chamber, a liquid metal partially filling the suction and pumping assembly, and an AC-powered reciprocating MHD pump. The AC-powered reciprocating MHD pump drives the liquid metal in an oscillatory manner, causing the suction and pumping of a working fluid. The pump further comprises at least one inlet conduit connected to the suction and pumping assembly for enabling the suction of a working fluid, at least one outlet conduit connected to the suction and pumping assembly for enabling the pumping of the working fluid, and a plurality of valves in the inlet and outlet conduits to regulate the flow of the working fluid.
