摘要： A liquid level sensor includes a liquid level responsive member that moves in response to changing liquid level, an electrically conductive contact associated with the liquid level responsive member, a circuit including a rectifying element and a) one or more conductive elements, or b) one or more resistive elements or c) one or more conductive elements and one or more resistive elements, wherein the contact is arranged to engage at least one of the elements in a, b, or c, and a power supply. The power supply is adapted to provide a voltage to the circuit causing a current flow in a first direction in the circuit wherein the current flows through the contact and to provide a current flow in a second direction in the circuit wherein the rectifying element prevents current flow through the contact.

摘要： In at least some implementations, a system includes a pump having an electric motor and a pump outlet, a controller coupled to the pump to vary the power provided to the motor to vary the flow rate of liquid discharged from the pump outlet, a pressure regulator having an inlet communicated with the pump outlet, a regulator outlet from which liquid is discharged from the regulator, a bypass outlet through which liquid is discharged from the regulator, and a pressure responsive valve that opens to permit liquid flow through the bypass outlet, and a flow sensor. The flow sensor is communicated with the bypass outlet to sense or determine a flow rate of liquid at or downstream of the bypass outlet, the flow sensor also communicated with the controller to provide an indication of the bypassed liquid flow rate to the controller.

摘要： In at least some implementations, a jet pump includes a main body having a first inlet, an inlet passage communicated with the inlet, a second inlet, an intake passage communicated with the second inlet, an outlet, and an outlet passage communicated with the outlet and with the intake passage, a jet carried by the main body and having a jet inlet communicated with the inlet passage so that fluid flowing in the inlet passage flows through the jet inlet, and a jet outlet having a flow area less than the jet inlet and less than the inlet passage. The main body is formed in one piece and the jet is a separate piece of material that is inserted into the inlet passage after the main body has been formed.

摘要： In at least some implementations, a fuel pump assembly includes a fuel pump having an inlet through which fuel enters the fuel pump and a first outlet from which pressurized fuel is discharged for delivery to an engine, and a second outlet through which some of the fuel discharged from the fuel pump is routed wherein that fuel is not delivered to the engine, wherein the second outlet has a flow area that permits a flow of fuel through the second outlet that is sufficient to reduce the maximum pressure of fuel downstream of the first outlet for delivery to an engine to between 1/10th and 1/25th of the output pressure of the fuel pump without flow through O the second outlet.

摘要： In at least some implementations, a fuel system includes a first fuel pump and a first switch adapted to be coupled to a power supply, and a second fuel pump adapted to be coupled to the power supply. A conductor is provided between a first node between the first fuel pump and the first switch and a second node to which the second fuel pump is electrically coupled or electrically communicated so that depending upon the state of the first switch power may be supplied to the first fuel pump and second fuel pump in series or in parallel.

摘要： In at least some implementations, an assembly includes a reservoir, a primary fuel pump having an inlet in communication with the reservoir's internal volume, an outlet, a motor and a pumping element driven by the motor and a secondary fuel pump with a body having first and second inlets and an outlet. The first inlet receives fuel from the primary fuel pump and a nozzle is communicated with the first inlet and fuel flows out of the nozzle into the body via the first inlet. The second inlet is in communication with the reservoir inlet, and the outlet is in communication with the internal volume. The flow of fuel through the nozzle draws fuel from the fuel source through the second fuel inlet and that fuel is combined with the flow of fuel from the nozzle and discharged into the reservoir.

摘要： In at least some implementations, a fuel supply module includes a reservoir and a fuel pump carried by the reservoir. The reservoir may include a body and a lid that define an internal volume to contain a supply of fuel, and the reservoir may include an inlet through which fuel enters the internal volume and an outlet from which fuel is discharged from the fuel supply module. The fuel pump is carried by the reservoir and has a first inlet communicating with the internal volume to take fuel into the fuel pump from the internal volume and a second inlet spaced above the first inlet relative to the direction of the force of gravity to take fluid or vapors into the fuel pump from the internal volume. The fuel pump includes an outlet from which fluid is discharged for delivery to an engine through the reservoir outlet.

摘要： In at least some implementations, a wire includes a core formed from an electrically conductive material and having an outer surface, and a polymeric insulator surrounding the core. The insulator has a resistivity of between 105 and 109 ohms/square, and the insulator has an inner surface engaged with the core. In at least some implementations, the core is formed from metal and has a conductivity of at least 1×10−6 Ωm. The insulator may include a base material and a conductive material in the base material, wherein the conductive material has a conductivity between 105 and 106 ohms/square. The insulator may have an outer surface that defines an outer surface of the wire and/or the insulator may have an inner surface engaged with the core.
