F04B 1700

US Classification:

4174231, 41742314, 310 71, 123509

Abstract:

A fuel sender assembly comprises an in-tank electrical connection to an electric fuel pump that is formed between a socket member and a plug element, in which the plug element includes a terminal that is received in a receptacle in the socket member. The socket element comprises a socket wall that extends about the socket face. The plug element also includes a plug wall that sealingly engages the socket wall to prevent the electrical contact from exposure to fuel vapors within the tank.

International Classification:

F04D 500

US Classification:

416203, 416237, 415 551

Abstract:

An impeller for a fuel pump for supplying fuel to an automotive engine from a fuel tank includes an impeller body having a substantially disk shape with opposing first and second faces and an outer circumference. The impeller body defines a rotational axis extending therethrough perpendicular to the first and second faces. A plurality of radially outwardly extending vanes extend from the outer circumference of the impeller body and are spaced circumferentially about the impeller body. Each of the vanes includes a first half extending from the outer circumference adjacent the first face and a second half extending from the outer circumference adjacent the second face. The second halves are rotationally shifted about the rotational axis relative to the first halves. The vanes are spaced un-evenly and in a non-repeating pattern about the outer circumference of the impeller body.

International Classification:

F04D005/00

US Classification:

415 554, 415119

Abstract:

A regenerative fuel pump comprising a housing, a pump cover having a first flow channel formed therein, a pump body having a second flow channel formed therein whereby the first flow channel and the second flow channel define a pumping chamber, and an impeller mounted between the pump cover and pump body and including a plurality of vanes spaced circumferentially about the impeller and defining a plurality of vane grooves. The vanes are spaced un-evenly in a non-repeating pattern about the impeller. The first and second flow channels each include an inlet end, an outlet end, and a stripper area defined as the area between the inlet end and the outlet end extending from the inlet end away from the flow channel. Each of the stripper areas including a plurality of grooves formed therein adapted to dampen pressure pulsations within the pumping chamber.

International Classification:

F04D 5/00

US Classification:

415 551, 416237

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.

International Classification:

H02P 6/00

US Classification:

318268, 310179, 310180

Abstract:

The present invention provides a system for controlling the speed of a motor by altering the magnetic field of the motor. The system includes field modification module, and a motor having field windings and a rotor. The field windings are configured to receive a driving signal that generates a magnetic field causing a rotation of the rotor. The field modification module is proximate the motor and alters the magnetic field in response to an input signal thereby controlling the speed and torque of the rotor.

International Classification:

US Classification:

123516, 13756524, 123509

Abstract:

A fuel sender assembly comprises an electric fuel pump held in a mounting plate which is, in turn, mounted in a fuel tank, such as an automotive fuel tank. The mounting plate includes a chamber wall that defines a pump chamber having an inboard end and an outboard end. The electric fuel pump is received in the pump chamber such that an inlet end, which includes a fuel inlet, is disposed within the fuel tank adjacent the inboard end of the pump chamber. The outlet end of the fuel pump includes the electrical terminals and is disposed adjacent the outboard end of the pump chamber so that the electrical terminals are accessible outside the fuel pump for connection to an external power source. A hermetic seal is formed between the fuel pump and the chamber wall to prevent vapors from escaping through the pump chamber. The fuel sender assembly permits electrical connections to be made to the fuel pump without requiring wires within the fuel tank.
