摘要： A pumping element for pressurizing a fluid within a fluid pump includes a plunger reciprocally disposed within a bore defined in a barrel. The plunger and barrel at least partially define a pressurization chamber into which fluid is pressurized. A flow path is defined between the plunger and the bore, the flow path permitting fluid to pass from the pressurization chamber during pressurization of fluid disposed therein. A collection chamber is formed between the plunger and the bore, the collection chamber being disposed adjacent to the bore and being part of a cooling circuit for the pumping element. A plurality of weep openings is defined in the barrel and is fluidly connected to the collection chamber. A reduced diameter portion of the barrel forms an annular reservoir that receives fluid from the weep openings.

摘要： The present invention relates to high speed control valves which are especially applicable for use in fuel injection systems. Producing a valve with a quick response time within acceptable packaging constraints and with a structure that allows the valve to be mass produced with consistent performance between valves is extremely problematic. By moving flow restrictions within the valve away from the valve seats, flow forces on the valve member can be reduced, while possibly also permitting a reduction in the necessary travel distance of the valve member to improve response time and other performance characteristics. The valve is particularly applicable in controlling hydraulic pressure applied to the closing hydraulic surface of a direct control needle valve in a fuel injector.

摘要： A common rail fuel injection system addresses three basic issues involving all common rail fuel injection systems. These include high performance, low variability and high efficiency. These issues are addressed by combining pressure intensification with a three way needle control valve, which exhibits substantial leakage only durring a brief instant when the valve is moving between seats. A quick acting needle control valve tightly coupled to a responsive direct control needle valve, as modified by relative timing with a flow control valve, can produce a wide variety of fuel injection rate shapes, including up to five or more discrete injections per engine cycle.

摘要： In some hydraulically actuated fuel injectors, a pressure communication passage extends from a pilot valve to the underside of a spool valve to control movement of the same. For the spool valve to move, a substantial amount of fluid flow past the pilot valve is required due to the relatively large amount of fluid that must be displaced by movement of the spool valve member. However, during cold start, when the oil in the pressure communication passage is relatively viscous, it is difficult to move enough fluid past the relatively small flow area through the pilot valve to allow the spool valve to advance to its upper position. Therefore, the fuel injector of the present invention includes a pressure communication passage that is connected to the underside of the spool valve to be separated from the branch that passes through the pilot valve.
摘要翻译：在一些液压致动的燃料喷射器中，压力连通通道从先导阀延伸到滑阀的下侧以控制其移动。为了使滑阀移动，需要大量的流体流过先导阀，这是由于相对大量的流体必须通过滑阀构件的移动来移动。然而，在冷启动期间，当压力连通通道中的油相对粘稠时，难以将足够的流体通过先导阀移动通过比较小的流动区域，以允许滑阀前进到其上部位置。因此，本发明的燃料喷射器包括压力连通通路，该压力连通通路连接到滑阀的下侧以与通过先导阀的分支分离。

摘要： The present invention relates to hydraulic systems including hydraulically actuated fuel injectors that have a pilot operated spool valve assembly. One class of hydraulically actuated fuel injectors includes a solenoid driven pilot valve that controls the initiation of the injection event. However, during cold start conditions, hydraulic fluid, typically engine lubricating oil, is particularly viscous and is often difficult to displace through the relatively small drain path that is defined past the pilot valve member. Because the spool valve typically responds slower than expected during cold start due to the difficulty in displacing the relatively viscous oil, accurate start of injection timing can be difficult to achieve. There also exists a greater difficulty in reaching the higher end of the cold operating speed range. Therefore, the present invention utilizes a fluid evacuation valve to aid in displacement of the relatively viscous oil during cold start conditions.
摘要翻译：本发明涉及包括液压致动燃料喷射器的液压系统，其具有先导操作的滑阀组件。一类液压致动燃料喷射器包括控制喷射事件开始的螺线管驱动先导阀。然而，在冷起动条件下，液压流体（通常是发动机润滑油）特别粘稠，并且通常难以通过限定在先导阀构件上的相对较小的排放通路的位移。由于滑移阀通常在冷启动期间响应比预期的慢，这是由于难以置换相对粘稠的油，因此可能难以实现准确的喷射正时启动。达到冷作业速度范围的较高端也存在较大困难。因此，本发明利用流体排出阀来帮助在冷起动条件下相对粘稠的油的位移。

摘要： A fuel injector includes an injector body with a plunger bore, a nozzle chamber, and a nozzle outlet that opens to the nozzle chamber. A plunger is positioned to reciprocate in the plunger bore between an advanced position and a retracted position. A portion of the plunger and a portion of the plunger bore define a fuel pressurization chamber. At least one of the injector body and the plunger define a main passage extending between the fuel pressurization chamber and the nozzle chamber. At least one of the injector body and the plunger define a restricted passage extending between the fuel pressurization chamber and the nozzle chamber. The restricted passage restricts flow of fuel to the nozzle chamber over the beginning portion of each injection event. The main passage is substantially closed over a portion of the plunger's movement between its retracted position and its advanced position.

摘要： A common rail fuel system includes a reverse flow check valve fluidly positioned between each of a plurality of common rail fuel injectors and an outlet of a high pressure pump. The reverse flow check valves divide the overall system fluid volume into an upstream common volume and a plurality of separate downstream volumes. The upstream common volume is greater than the sum of the separate downstream volumes. The reverse flow check valve is movable between a first configuration with a large flow area and a second configuration with a small flow area. The reverse flow check valve associated with each of the individual fuel injectors may be housed in a quill that fluidly connects the fuel injectors to the high pressure common rail.
