Abstract
A pump assembly is fluidly coupled to a vehicle engine for moving a fluid. The pump assembly includes a pump housing and an impeller disposed in the pump housing for moving the fluid in the pump housing towards an outlet. Additionally, the pump assembly includes a valve assembly integrated with the pump housing. The valve assembly includes a barrel disposed in the pump housing and having at least one inlet, wherein the at least one inlet is configured to provide controlled flow of the fluid into the pump housing. A sleeve is rotatably coupled to the barrel for selectively controlling the flow of the fluid into the at least one inlet of the barrel. Additionally, the valve assembly includes an actuator assembly operably coupled to the sleeve and configured to rotate the sleeve between a first position and a second position.
