Abstract: A fluid pump includes an electric motor with a casing and a drive shaft extending from the casing, a pumping element coupled to the drive shaft for rotation with the shaft to take in fluid and discharge it under pressure. The fuel pump casing may be sealed and a housing coupled to the casing may provide the inlet and outlet passages for fluid flow to and from the pumping element. The housing may be received in or communicated with other housing or module assemblies to provide a wide array of fuel pump assemblies. The pumping element may include one or more gear rotors, a turbine pumping element, or other pumping element, as desired.

Abstract: A low cost bypass pressure regulator for liquid flowing preferably in a returnless fuel system for a combustion engine communicates operatively with a conduit which flows fuel from a fuel pump of the fuel system to at least one fuel injector of the combustion engine. The pressure regulator preferably has a valve head disposed at least in-part in a valve chamber defined by a circumferentially continuous inner surface carried by a valve body and which transitions radially outward with respect to a center axis and in a downstream direction. The valve head preferably tapers radially inward with respect to the center axis in an upstream direction and from a peripheral outer edge of the head.

Abstract: A fuel delivery system for a combustion engine has a fuel tank which defines an access hole preferably communicating through either the top wall or bottom wall of the tank. An associated top or bottom flange, both having a fuel channel for flowing fuel out of the tank, sealably covers the access hole. A fuel pump module is located in the fuel chamber of the tank and has a universal, structural, pod which engages either the top or bottom flange while preferably maintaining an axial upright position. The pod defines an axially extending first bore for housing a fuel pump and preferably an electric pump motor and a second bore defined by a cylindrical inner face and spaced radially outward from the first chamber for housing a reversable filter cartridge of the module. The pod also has a fuel discharge nozzle which generally defines a counter bore that communicates axially with the second bore.

Abstract: A fuel pump assembly has a pump mounted to an electric motor by a spring clamp device preferably having a plurality of arms spaced circumferentially around the pump and extending axially generally parallel to an axis of rotation of the motor, from a common base member. The base member is preferably received by the motor, and each arm preferably has a clip which projects radially inward to contact an outboard end face of the pump. The clips are preferably disengageable from the pump and exert a controlled force on the pump, thus producing a consistent and controlled clamping force across the housing encasement to eliminate any potential distortion of the preferably plastic housing.
