    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： Mixing of lubrication fluid and pumped fluid within a pump can undermine lubricity of the lubrication fluid and/or contaminate the pumped fluid (e.g. fuel) with lubrication fluid. In order to reduce mixing of fluids within a high pressure pump of the present disclosure, a lubrication fluid is supplied to the high pressure pump. A low pressure pump supplies a second fluid to the high pressure pump. The pressure of the second fluid is increased within at least one piston bore of the high pressure pump. Mixing of the lubrication fluid and the second fluid is reduced by fluidly connecting a weep annulus which is opened to the at least one piston bore to a low pressure pump inlet of the low pressure pump.

    摘要： Because of the relatively high pressures experienced within fuel injectors, several internal components can undergo substantial deformation each time fuel is pressurized to injection levels. In some instances, such as when a solenoid operated control valve is positioned near a distortion region, the internal distortion can cause a fuel injector to behave with less predictability, and can undermine consistency from one fuel injector to another, since distortion levels and affects therefrom are likely to vary substantially from one injector to another. In order to desensitize fuel injector performance to this internal distortion, a deflection cavity is disposed within the fuel injector between the distortion region and the needle valve of the fuel injector. This strategy finds particular applicability to needle control valves disposed deep within fuel injectors in order to control fluid pressure on a closing hydraulic surface of a direct control needle valve, which opens and closes the nozzle outlets.

    摘要翻译： 由于燃油喷射器中经历的压力相对较高，每当燃料被加压至喷射水平时，几个内部部件可能经历相当大的变形。 在一些情况下，例如当螺线管操作的控制阀位于变形区域附近时，内部变形可能导致燃料喷射器以较少的可预测性表现，并且可能破坏从一个燃料喷射器到另一个的一致性，因为失真水平和影响 可能从一个注射器到另一个注射器显着变化。 为了使燃料喷射器的性能降低到这种内部变形，在燃料喷射器内在燃料喷射器的变形区域和针阀之间设置偏转腔。 该策略特别适用于布置在燃料喷射器内部的针控制阀，以便控制打开和关闭喷嘴出口的直接控制针阀的关闭液压表面上的流体压力。
