摘要： Reducing leakage within fuel injectors is one way in which the efficiency of the overall fuel injection system can be improved. In most fuel injectors that include a direct control needle valve, the needle valve member is still biased toward a closed position by a spring that is located in a spring chamber connected to a low pressure vent. In many instances, the needle valve member is guided in a tight clearance region adjacent the spring chamber. Since the internal plumbing of the fuel injector is connected to a high pressure rail during and between injection events, static leakage across the guide region of the needle valve member can reduce efficiency. Static leakage is reduced in the present invention by connecting the spring chamber to the common rail instead of to a low pressure vent. Such a fuel injector could find potential application in any directly controlled fuel injection system, but is particularly applicable in common rail systems in which the fuel injector remains fully pressurized between injection events.
摘要翻译：减少燃油喷射器内的泄漏是提高总体燃油喷射系统效率的一种方法。在包括直接控制针阀的大多数燃料喷射器中，针阀构件仍然通过位于连接到低压通风口的弹簧室中的弹簧偏压到关闭位置。在许多情况下，针阀构件在与弹簧室相邻的紧密间隙区域中被引导。由于燃料喷射器的内部管道在喷射事件期间和在喷射事件期间连接到高压轨道，所以穿过针阀构件的引导区域的静态泄漏可以降低效率。通过将弹簧室连接到共轨而不是低压通风口，本发明中静电泄漏减少。这种燃料喷射器可以在任何直接控制的燃料喷射系统中发现潜在的应用，但是特别适用于燃油喷射器在喷射事件之间保持完全加压的共轨系统中。

摘要： A pump has a housing defining at least one pumping chamber, and a plunger slidably disposed within the at least one pumping chamber. The plunger is movable between a first and second spaced apart end positions to pressurize a fluid. The pump also has a driver operatively engaged with the plunger to move the plunger between the first end position and the second end position. The pump further has a high-pressure outlet in fluid communication with the at least one pumping chamber. The high pressure outlet passes pressurized fluid during movement of the plunger between the first end position and the second end position. The passing of pressurized fluid through the high-pressure outlet terminates before the plunger completes movement from the first end position to the second end position.

摘要： The pump described herein provides a potentially lower cost alternative to conventional high-pressure pumps by providing a head, a plunger, and a control valve assembly. The head defines a valve bore having a first diameter, a plunger bore having a second diameter, and an intermediate chamber having a third diameter. The plunger is configured to reciprocate within the plunger bore. The plunger, the plunger bore, and the intermediate chamber at least partially define a pumping chamber. The control valve assembly is coupled to the head and includes an actuator moveable in response to an input signal and a valve element coupled to the actuator. The valve element is received within the valve bore and moveable between an open and a closed position. The valve element includes a body having a fourth diameter and a valve head having a fifth diameter. The first diameter is no larger than the second diameter.

摘要： A fuel injector includes a homogenous charge nozzle outlet set and a conventional nozzle outlet set controlled respectively, by first and second needle valve members. One of the needle valve members moves to an open position while the other needle valve member remains stationary for a homogeneous charge injection event. The former needle valve member stays stationary while the other needle valve member moves to an open position for a conventional injection event. One of the needle valve members is at least partially positioned in the other needle valve member. Thus, the injector can perform homogeneous charge injection events, conventional injection events, or even a mixed mode having both types of injection events in a single engine cycle.
