Abstract
A bi-directional pump comprises a pump housing, and the pump housing comprises a pump outlet. A fluid pressurizer is positioned in the pump housing and configured to provide fluid flow selectively in a first direction and a second direction. A first passage and a second passage are positioned in the pump housing. A junction is fluidly positioned, in the pump housing, connecting the first and second passages to the pump outlet. A flow controller is positioned in the pump housing to move relative thereto, between a first position, placing the first passage, in fluid communication, with the pump outlet via the junction when the fluid pressurizer provides fluid flow in the first direction, and a second position placing the second passage, in fluid communication with the pump outlet, via the junction when the fluid pressurizer provides fluid flow in the second direction.
