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 fuel pump assembly 10 including a motor 12, a drive shaft 14 which is rotatably coupled to motor 12, an impeller 16, and a chamber assembly 18. Fuel pump assembly 10 has improved efficiency due to the substantial reduction and/or elimination of frictional contact between impeller 16 and the respective interior surfaces 70, 72 of chamber 18.

Abstract: A speed monitoring and control method for a brushless motor controlled by a controller which provides switching control signals to a plurality of switching elements includes comparing one line voltage of the motor with a signal representing a voltage at the neutral node of the motor, to generate a comparison signal. The method also includes ANDing the comparison signal with a switching control signal to generate a composite feedback signal representative of a rotational speed of the motor's rotor relative to a speed of a rotating magnetic field generated by the stator.

Abstract: A fuel pump is used for supplying fuel from a fuel tank to an automotive engine. The fuel pump includes a pump housing having an inlet end for receiving fuel from the fuel tank. A brushless DC motor is positioned within the pump housing and includes a rotatable rotor having magnets therein and a central aperture formed through the rotor. A plastic helical-shaped impeller is positioned within the central aperture for rotation with the rotor about a central axis for pumping fuel through the housing to the engine. The impeller has a plurality of vane blades with blade tips secured to the rotor to prevent tip losses. Each vane blade has a leading edge configured to generate laminar fluid flow and reduce vapor generation at the inlet end of the impeller.

Abstract: An electric-operated fuel pump (20) has a vaned impeller (28, 28') that is disposed within a pumping chamber (27) for rotation about an axis (21). The pumping chamber has a main channel (42) extending arcuately about the axis to one axial side of the impeller. The main channel has a radially outer margin that opens (58) along at least a portion of the channel's arcuate extent to an adjoining contaminant collection channel (56) 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 (40). A sump (72) is disposed at the end of the contaminant collection channel proximate the outlet. The impeller (28') has a ring (70) girdling the impeller vanes (52) with a radially inner surface that is slightly concave in axial cross section.

Abstract: In one embodiment of the present invention, a fluid level sensor includes a resistive element and a float coupled to a contact. The float moves in response to the fluid level, causing the contact to follow a path on the resistive element. The resistive element includes a layer of resistive material disposed on an insulating substrate. The resistive element also includes a layer of conductive material disposed on the layer of resistive material. The conductive material is disposed in segments along the path followed by the contact. This embodiment of the present invention provides a high-durability fluid level sensor which further provides low electrical noise.
