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.

Abstract: An electric-operated fuel pump has a vaned impeller that is disposed within a pumping chamber for rotation about an axis. The pumping chamber has a main channel extending arcuately about the axis to one axial side of the impeller. The main channel has a radially outer margin that opens along at least a portion of the channel's arcuate extent to an adjoining contaminant collection channel which extends arcuately about the axis and which is effective, as the pumping element rotates, to collect certain fluid-entrained particulates expelled from the main channel and to convey such collected particulates toward the pump outlet. A sump is disposed at the end of the contaminant collection channel proximate the outlet. Several grooves in the seal surface between inlet and outlet, which is called “strip area.” The grooves are extended radially outward, the angles match the impeller vane angles and these grooves prevent leakage of the contaminations.

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 vehicle regenerative-type fuel pump which reduces the possible accumulation and effects of contamination relative to impellers with outer ring members. The outer ring members have non-uniform configurations (slanted, curved, grooved, etc.) which reduce the affects of contamination which can cause wear and roughing of the outer surface resulting in higher torque and reduced pump efficiencies.

Abstract: A fuel delivery module for an automotive fuel delivery system includes a reservoir and a fuel pump. The fuel pump delivers fuel from the tank to the reservoir via a fuel tank inlet and reservoir outlet and from the reservoir to the engine via a reservoir inlet and engine outlet. The reservoir is formed with a plurality of contaminant traps for collecting contaminants contained in the fuel as the fuel is pumped through the reservoir such that the contaminants settle unto said contaminant traps thereby reducing the amount of contaminants entering the reservoir inlet.

Abstract: A pump (10) has a housing containing an internal pumping chamber (30). A fluid inlet (32) and a fluid outlet (34) are spaced arcuately apart about an axis (12), and an impeller (20) within the housing rotates about the axis to pump fluid from the inlet to the outlet. The impeller has mutually parallel opposite faces (40, 42) circumferentially bounded by a vaned periphery (38). The impeller has a pattern of through-holes (46) extending between its faces and the one face that confronts a wall surface of the housing to which the inlet is proximate has, in association with each through-hole, a groove (44) that adjoins and tails circumferentially away from the respective through-hole in a sense opposite the sense in which the impeller rotates to pump fluid from the inlet to the outlet. The groove inclines and provides a reaction surface against which fluid exerts a lifting force to aid in force-balancing the impeller.
