    Abstract: A fuel pump includes a pump housing with a motor which is adapted to rotate a shaft with a ring impeller mounted thereon. A bottom is mounted to the housing and has an outlet. A cover is mounted on an end of the housing and is attached to the bottom with the ring impeller enclosed between the cover and the bottom. The cover includes a first side having a fuel inlet orifice and a second side having a flow channel formed therein. The inlet orifice extends through the cover in fluid communication with the flow channel. The flow channel includes an inlet, a ramp, a ramp end and a main channel. The inlet includes a smooth curved profile. The ramp connects the inlet to the ramp end. The ramp end connects the ramp to the main channel.

    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.

    Abstract: A rotary fuel pump employs pressure balancing features on the non-vaned side of the impeller to provide localized application of fluid forces so that the impeller is more precisely balanced within the pumping chamber. A generally disc-shaped impeller body has an impeller with a body-side surface and a cover-side surface. The cover-side surface defines an impeller flow channel extending circumferentially around the impeller. The impeller includes a plurality of vanes positioned at least partially within the impeller flow channel. The body-side surface has a plurality of discontinuous undercut regions each coaxially aligned with at least a portion of the impeller flow channel. The impeller has a plurality of apertures wherein each aperture connects the impeller flow channel with a respective undercut region, whereby pressure forces against the impeller from the fuel are substantially balanced in the axial direction.
