摘要： A modular fuel delivery system including a reservoir in a fuel tank, an electric fuel pump in the reservoir, and a jet pump for pumping fuel from the fuel tank into the reservoir wherein overflow from the reservoir is recirculated by the jet pump back into the reservoir to minimize mixing of potentially hot overflow with cooler bulk fuel in the fuel tank. A recirculation fluid flow path extends from the reservoir to a secondary inlet of the jet pump adjacent a small diameter end of a venturi passage in the latter. A valve closes the recirculation flow path when the reservoir is not overflowing and opens the recirculation flow path when the reservoir is overflowing. A portion of the recirculation flow path is above the maximum surface elevation of fuel in the fuel tank so that the pressure head at the recirculation inlet exceeds the pressure head at the main inlet of the jet pump open to the fuel tank. Accordingly, when the recirculation flow path is open, the jet pump entrains fuel from the recirculation inlet in preference to fuel from the main inlet.
摘要翻译： 模块化燃料输送系统，其包括在燃料箱中的储存器，储存器中的电动燃料泵，以及用于将燃料从燃料箱泵送到储存器中的喷射泵，其中来自储存器的溢流被喷射泵再循环回到储存器 以尽可能减少潜在的热溢流与燃料箱中较冷的散装燃料的混合。 再循环流体流动路径从储存器延伸到喷射泵的次级入口，邻近文丘里通道的小直径端。 当储存器不溢出时，阀关闭再循环流动路径，并且当储存器溢出时打开再循环流动路径。 再循环流动路径的一部分高于燃料箱中的燃料的最大表面高度，使得再循环入口处的压头超过在燃料箱开口的喷射泵的主入口处的压力头。 因此，当再循环流路打开时，喷射泵优先于来自主入口的燃料从再循环入口夹带燃料。

摘要： An evaporative emission control system of an internal combustion engine's fuel system including a vent valve. The vent valve provides a mechanism for closing the evaporative emission control system creating a pressure differential between system and atmospheric under various conditions whereby the system can be automatically diagnosed. The vent valve relieves pressure or vacuum in the system that exceeds a threshold necessary to detect the presence of leaks. The vent valve includes a vacuum actuator providing a low restriction flow path for system purges.

摘要： A fuel tank has a filler neck terminating in an upwardly opening well, and a paddle overlying the well has a pivoted arm extending adjacent a vent valve. The arm causes the valve to restrict flow through a vent orifice when fuel is not being introduced through the filler neck, but pivots to allow the valve to open the orifice in response to introduction of liquid fuel through the filler neck. A float has an actuating member adapted to cause the valve to restrict flow through the orifice when the level of liquid fuel in the tank approaches the maximum level desired.

摘要： A vapor fuel recovery system for fuel tanks is provided. The vapor recovery system comprises: a canister that captures vapor fuel expelled from the fuel tank; a vent valve that controls ventilation of vapor fuel from the fuel tank to the canister; and a vent bypass disposed between the canister and the vent valve that controls the flow of vapor fuel from the fuel tank to the on-board recovery canister when a fuel level in the fuel tank is full. The bypass includes a bypass valve and at least one orifice.

摘要： A trunk mounted fuel tank assembly including a cradle, a fuel tank, and at least one retention strap is disclosed. The cradle includes a back portion and bottom portion with a fuel feed passage that is placed over a surface of a trunk. The fuel tank includes a fuel line that is placed about the back portion and bottom portion of the cradle. The fuel line extends through the fuel feed passage and a passage in the surface of the trunk. The at least one retention strap includes a first leg and a second leg that is placed over a top portion of the fuel tank for retaining the fuel tank to the cradle.

摘要： A combined filler neck and vapor vent line valve is provided by inner and outer pipes that are maintained in concentric relation by a sleeve tightly inserted between the outer pipe and an out-turned flange at the end of the inner pipe. This provides a convenient path out of the fuel tank for displaced tank vapors. Vapor control is provided by a stepped cylindrical valve body that rides up and down within the upper end of the inner pipe and the sleeve so that a seal on the outside of the valve body can cover and uncover openings in the flange to block and un-block a vapor path to the canister.

摘要： Warmed returned fuel from a vehicle fuel injection system is returned only a segregating canister in the tank, and pumped back therefrom preferentially, with make up fuel allowed in only as needed. Overall heating of the stored fuel, and consequent running losses, are substantially reduced, with no ill effects on vehicle operation.
