摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
