    摘要: A fuel pump includes a housing, and a motor. A single sided impeller has first and second impeller flow channels each including a plurality of vanes. The impeller defines a flow passageway extending therethrough. A cover is attached to the housing and has a cover surface that defines first and second cover flow channels. The cover flow channels receive fuel from inlets formed in the cover. The first and second cover flow channels are aligned with the first and second impeller flow channels and receive fuel through the inlets and deliver fuel to outlets. A body is positioned within the housing and defines an impeller chamber to receive the impeller, and a first outlet passageway fluidically connected to the first cover flow channel and impeller flow channel. A second outlet passageway formed within the cover is fluidically connected to the second cover flow channel and impeller flow channel.

    摘要: A fuel pump is provided having improved efficiency by lowering the wet circle index of the pump while maintaining robust axial clearances to meet the demands of an automotive application. One embodiment includes a fuel pump for pressurizing fuel for delivery to an engine of a motor vehicle. The fuel pump generally comprises a housing, a motor, a single sided impeller, a cover and a body. The provision of a single sided impeller greatly reduces the wet circle index and improves the pump efficiency. The cover, impeller, and body are structured to axially balance the impeller which is free floating on the shaft of the motor.
