Abstract: The present invention provides a system for controlling speed of the fuel pump. The system includes a fuel pump, a controller, and a field modification module. The fuel pump is configured to receive a driving signal causing the fuel pump to pump fuel. The controller is configured to determine a desired fuel pump speed and generate a control signal based on the desired fuel pump speed. The field modification module is located proximate the fuel pump and is in communication with the controller to receive the control signal. The field modification module generates a flux in response the control signal thereby controlling speed and torque of the fuel pump.

Abstract: 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.

Abstract: A pressure regulated valve is provided for a mechanical returnless fuel system for an automotive vehicle that includes a fuel pump for supplying fuel from a fuel supply to an engine. The pressure regulating valve includes a conduit in fluid communication with the pump outlet. The valve includes a valve seat and a valve body having a frustoconical seal surface. A spring biases the valve body to close the valve body against the valve seat. During operation, increased fuel pressure from the pump opens the valve body to discharge excess fuel to the fuel supply.

Abstract: A mechanical returnless fuel system comprises a fuel pump having an output for supplying fuel to fuel injectors of an automotive engine. The fuel system includes a pressure regulating valve that returns a portion of the pump output in excess of engine fuel usage to the fuel supply. The pressure regulating valve results in a fuel pressure that varies as a function of engine fuel demand. During operation, a controller determines a projected engine fuel demand, then determines an estimated fuel pressure based upon the projected engine fuel demand. The controller utilizes the estimated fuel pressure to provide a more accurate calculation of the opening time for the fuel injectors and thereby improve engine control.

Abstract: 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.

Abstract: A ring impeller includes a central hub with a first row of vanes extending from the hub and a second row of vanes extending from the hub adjacent to and staggered from the first row of vanes. The vanes in each row are grouped to form adjacent vane pairs and a partition wall is positioned between each of the vanes within the vane pairs. A rib extends radially from the hub in alignment with the partition wall and is positioned between each vane pair. The bottom thickness of the partition wall is the same thickness as the rib. The partition wall includes a reduced material area at its forward and rear edges. The vanes in the first row are unevenly spaced and the vanes in the second row are spaced equidistantly between the vanes in the first row. The spacing of the vanes in the first row may be about 70% to about 140% of a spacing equal to an equal spacing. Some of the vanes may have a height that is less than the height of other vanes.

Abstract: An impeller for a fuel pump for supplying fuel to an automotive engine from a fuel tank includes an impeller body with a plurality of vanes having a front side and a back side extending radially outward therefrom. A plurality of partitions are interposed between the vanes and extend a radially shorter distance than the vanes. The partitions and the vanes define a plurality of vane grooves. Each of the vanes includes a root which is adjacent the impeller body and a distal end. The vanes have a thickness which varies such that the vanes are thickest at the root and gradually become thinner as the vanes extend outward to the distal end. A ring portion is fitted around the impeller and connected to the distal ends of the vanes such that a plurality of extending fuel flow passages are formed between the vanes, the partitions, and the ring portion.

Abstract: An in-tank fuel supply unit is provided for supplying fuel from a fuel tank to an engine. The fuel supply unit generally comprises a fuel delivery module and a jet pump assembly selectively attachable to the fuel delivery module. The fuel delivery module has a housing defining a reservoir and includes a fuel pump for pressurizing fuel in the reservoir. The jet pump assembly has a suction tube defining a suction chamber and a nozzle situated inside the suction chamber. The nozzle receives pressurized fuel from the fuel pump and sprays the fuel from a nozzle tip at high velocity to draw additional fuel into the suction chamber through an inlet formed in the suction tube.
