摘要： An in-tank fuel pump reservoir assembly for drawing fuel from a fuel supply tank and discharging the fuel under pressure to an engine. The assembly includes a reservoir canister that partially defines a reservoir chamber and is mounted within a fuel tank. A reservoir inlet admits fluid into the reservoir chamber from the fuel tank. A reservoir outlet allows fuel to flow from the reservoir chamber to an engine through a fuel line. A reservoir filling device draws fuel into the reservoir chamber from the fuel supply tank through the reservoir inlet. A fuel pump assembly disposed within the canister draws fuel from the reservoir chamber and discharges at least a portion of that fuel to the engine through the reservoir outlet. A modular fuel delivery pod includes the fuel pump assembly, the reservoir filling device, and the inlet check valve. The pod connects to the canister to cooperatively define the reservoir chamber. The assembly is readily adaptable to multiple fuel tank applications by selecting respective canisters and fuel pump assemblies that are compatible with such applications.

摘要： A multi-level fuel pickup system has a float valve in communication with a first fuel passage having an open end disposed at a first height within the fuel tank spaced from the bottom of the fuel tank to prevent fluid flow through the first fuel passage when liquid fuel is absent adjacent its open end. A second fuel passage communicates adjacent the bottom of the fuel tank and below the first height and fuel is drawn through this fuel passage when a low level of fuel remains in the fuel tank. A fuel control valve is manually adjustable to control through which of the fuel passages fuel is drawn. Preferably, each of the fuel passages is at least partially formed in a valve body mounted within the fuel tank and the float valve comprises a spherical float received in a bore in the valve body and is responsive to the level of fuel within the bore.

摘要： A liquid propane fuel storage and delivery system for a vehicle engine with a fluid handling component module removably top-mounted on an appropriate vehicle-mounted pressurized liquid propane fuel storage tank. The module includes: (1) a fuel tank 80% stop-fill subsystem that automatically opens and closes the tank fill port to control tank fuel fill; (2) a hydrostatic back-check valve to prevent reverse fuel flow from the tank to atmosphere via the fill port; (3) an excess fuel bypass return check valve that maintains a predetermined amount of pressure in the fuel line as required to achieve acceptable engine performance; (4) a return check bypass valve that bypasses the return check valve to allow an extra amount of vapor-purging liquid fuel to be flushed through the system and returned to the tank through the fill solenoid prior to engine start-up; (5) an excess flow valve to limit fuel flow to atmosphere in case of a severed fuel line; (6) a supply solenoid valve assembly that prevents fuel flow to the engine if the solenoid is not energized; (7) a supply line over-pressure check valve to prevent a pump outlet line from being overstressed due to pressure build up; (8) a tank pressure relief valve; (9) a tank drain valve; (10) a "leak-free" electrical coupling; and (11) a fuel pod assembly housing one or two fuel pumps pumping either in parallel or series flow.

摘要： A fuel handling system for an internal combustion engine having a vapor separator for receiving fuel from a remote tank and a pump for delivering the fuel under high pressure to a fuel injector of the engine while providing vapor separation. The separator has an inlet for receiving fuel from the tank, an outlet for enabling fuel to be removed and delivered to the engine, at least one return for enabling fuel not used by the engine to be returned to the separator, and a vent for removing fuel vapor from a gas dome above a pool of liquid fuel within the separator. The inlet has a valve controlled by a float in the reservoir for admitting fuel to maintain the level of liquid fuel in the separator. To retard foaming and excessive vaporization of liquid fuel in the separator, the separator has a perforate baffle between any return and the liquid fuel pool. To prevent any stream of returned fuel, vapor and/or air from impinging against the fuel pool, the baffle preferably has a plurality of through-openings which enable liquid fuel to pass through the baffle to the pool while deflecting any return stream away from the fuel pool. The baffle preferably extends outwardly to the separator sidewall for preventing any return stream from passing around the baffle and directly impinging against the liquid fuel while at least slightly pressurizing gas below the baffle for controlling vapor venting to the engine.

摘要： A level sensor and fuel pump assembly insertable through an access hole of a fuel tank so that an elongated fuel pump is disposed substantially completely within the fuel tank, and so that a flange of the assembly covers the hole and is engaged sealably to the wall of the fuel tank. The fuel level sensor has an arm which projects generally laterally when in a biased operating position from the elongated fuel pump to a float at a distal end. During insertion of the fully pre-assembled fuel sensor and pump assembly through the access hole of the fuel tank, the fuel level sensor is pivoted from the biased operating position to a collapsed position by an external force thus pivoting the fuel level sensor generally parallel, and closely orientated, to the fuel pump. This temporary orientation permits insertion of the fuel pump assembly through the relatively small access hole of the tank. After insertion, the external force is released and the fuel level sensor pivots from the collapsed position back to the operating position.

摘要： A flow control valve for an internal combustion engine fuel delivery system that includes a valve body having a fuel inlet for connection to a fuel supply and a fuel outlet for connection to the fuel pump, so that the pump can draw fuel under vacuum from the supply through the valve and deliver fuel to an engine. A valve element is disposed within the valve body between the inlet and the outlet, and springs urge the valve element to a closed position within the valve body. A diaphragm is also disposed within the valve body between the valve element and the fuel outlet, and is coupled to the valve element such that suction vacuum applied by a fuel pump to the valve body outlet operates the diaphragm to open the valve element against forces applied by the valve springs to permit flow of fuel from the supply through the valve to the pump. The diaphragm is coupled to the valve element by a resilient detent mechanism responsive to vacuum at the valve outlet above a preselected level for releasing the coupling engagement between the diaphragm and the valve element, such that the valve is closed by the springs to terminate flow of fuel to the valve outlet.
