摘要： 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.

摘要： A pass-through electrical connector assembly with a body having at least one through-hole formed therein. A pin is forced into the through-hole and held by the body. The pin has a shank with opposed ends, each with a blind hole to receive a wire and a solid center portion that seals the wires and the pin. The pin has a tip with a barb at one end and a head with a shoulder at the other end which captures the pin in the body after the pin is forced into the through-hole when the shoulder engages the body. The shank has a circumferential surface that is press-fit within the through-hole to form a seal between the pin and the body. The body can then be sealed to a mating flange of a fluid-holding tank.

摘要： 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 reversible 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. Fuel flows into the pump through an inlet defined by the pod and pressurized fuel flows from the pump and into the second bore via a fuel passage preferably defined by the pod. The filter cartridge preferably has a filter element generally spaced from the pod within the second bore for filtration efficiency by a primary end retainer and an opposite secondary end retainer. The end retainers generally seal to the pod within the second bore thus flowing all of the pressurized fuel from the fuel passage and through the filter element before being discharged from the second bore as supply fuel and/or bypass fuel. Preferably, filtered fuel flows through the primary end retainer as system supply fuel to a combustion engine and the remaining filtered fuel flows through the secondary end retainer as bypass fuel back into the fuel tank chamber.

摘要： A fuel shut-off system for a carburetor substantially reduces or prevents the delivery of fuel to an engine when the engine is turned off and as it coasts to a stop. The fuel shut-off system preferably reduces or eliminates the pressure differential across a nozzle through which fuel is delivered from a fuel chamber through a fuel-and-air mixing passage of the carburetor and into the engine. In this manner, the flow of fuel through the nozzle is reduced and preferably eliminated immediately upon engine turn-off to prevent the after-fire and associated problems within a residually hot exhaust system. The system incorporates an actuator, preferably a solenoid valve, having a first position which obstructs a vacuum bypass passage communicating between the fuel chamber and the fuel-and-air mixing passage, and a second position which enables communication between the vacuum bypass passage and a fuel chamber passage which otherwise communicates with a near atmospheric pressure source.

摘要： A low cost bypass pressure regulator preferably for a returnless fuel system supplying liquid fuel to a 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 from a downstream peripheral outer edge of the head. In a closed position, the valve head engages a seat carried by the body with the peripheral outer edge downstream of the seat and radially spaced from and fitted closely to the valve chamber continuous inner surface thus defining a close fit region therebetween. As the valve head opens, the flow cross-section enlarges which reduces or eliminates oscillation of the valve head.
