摘要： A fuel system is disclosed having a fuel nozzle which receives pulsed, pressurized fuel for injection into the intake of an engine. The nozzle has a valve seat assembly with an upstream and a downstream seat interconnected by a longitudinal passage and by a bypass extending from upstream of the first seat to a location intermediate of the two seats. A poppet valve assembly has interconnected upstream and a downstream valve members operable relative to respective valve seats to regulate flow through the nozzle. A biasing member urges the valve member into a closed position in which the upstream valve member is unseated and the downstream valve member is seated to interrupt flow therethrough and out of the nozzle. Introduction of a fuel pulse into the nozzle moves the upstream valve member into engagement with its valve seat to thereby unseat the downstream valve member to allow fuel flow through the bypass around the upstream valve/seat and out of the nozzle through the open, downstream valve/seat. The bypass defines a fixed orifice for fuel flow through the nozzle and can produce a majority of the pressure drop and fuel metering functioning the fuel system.
摘要翻译：公开了一种燃料系统，其具有燃料喷嘴，燃料喷嘴接收用于喷射到发动机的进气口中的脉冲式加压燃料。喷嘴具有阀座组件，其具有通过纵向通道和从第一座椅的上游延伸到两个座椅中间位置的旁路相互连接的上游和下游座椅。提升阀组件具有互连的上游侧和下游阀构件，其可相对于相应的阀座操作以调节通过喷嘴的流动。偏置构件促使阀构件进入关闭位置，在该位置，上游阀构件被卸下并且下游阀构件就位以阻止流过其中并流出喷嘴。将燃料脉冲引入喷嘴使上游阀构件与其阀座接合，从而使下游阀构件脱离接头，以允许燃料通过上游阀/阀座周围的旁路流过喷嘴，并通过开放的下游阀 /座位。旁路限定了用于燃料流过喷嘴的固定孔，并且可以产生大部分压力降和燃料计量功能。

摘要： A fuel injection nozzle has a tubular body adapted to receive fuel, a tubular seat member mounted to the body, the seat member having an opening for discharging fuel and a valve seat surrounding the opening, a poppet valve member engageable with the valve seat to interrupt fuel flow through the opening, and an extension spring anchored to the body and to the valve member and biasing the valve member to engage the valve seat. The extension spring is a helically coiled spring with each coil lying close to the adjacent coils and with the coils at one end overlying an end of the body to anchor the spring to the body and to cause fuel flowing through the nozzle to pass between the coils of the spring; the spring thereby acts as a filter for fuel to be discharged by the nozzle. The seat member is axially movable relative to the body to adjust the length of the spring and thus the bias on the valve member whereby the desired valve-opening pressure differential may be established. The body is adapted to receive fuel through a restriction member that limits fuel flow through the opening. The valve member has a shank with a valve element at one end and a head at the other end, the shank being formed as a pin and the valve element as a ball that is welded to the pin.

摘要： A fuel cell plate having a first plate having an inlet aperture and a second plate disposed against the first forming a conduit. The conduit has a continuous seam formed between the first plate and the second plate to facilitate a transport of water to the outlet aperture. The plates can include various indentations and protuberances that form portions of the conduit. The fuel cell plate is well suited for use in a vehicle fuel cell stack for reducing water retention in a fuel cell without increasing the number of required components and fabrication cost of the fuel cell plate.

摘要： A device and method to extract water from a moisture-rich fuel cell flowpath. A water transport unit is integrated into the fuel cell so that liquid water stagnation within flow channels and manifolds is reduced. In one embodiment, the device includes numerous flowpaths that include an active region and an inactive region. The water transport unit includes a hydrophilic member such that upon passage of a fluid with the excess water through the inactive region of the device flowpath and into the presence of the hydrophilic member, it absorbs excess water from the fluid.
