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.

摘要： A pressure relief valve is disclosed. The pressure relief valve comprises a body, a valve member, and a resilient member. The body includes a guide bore, a seat surface, an inlet, a first outlet, and a second outlet. The valve member is received within a portion of the body and includes a guide portion received within the guide bore, a valve seat configured to sealingly engage the seat surface, and an internal passage. The resilient member biases the valve seat into engagement with the seat surface. The valve member is moveable between a first position in which the inlet is fluidly blocked from the first outlet and the second outlet, a second position in which inlet is fluidly coupled to the first outlet but not to the second outlet, and a third position in which the inlet is fluidly coupled to the first outlet and the second outlet.

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： Mixing a pumped fluid with a lubrication fluid within a pump can undermine the lubricity of the lubrication fluid. In order to reduce mixing of fluids within a pump of the present disclosure, a pump is provided that comprises a housing, a piston, a first annulus, and a second annulus. The housing includes an inlet for the pumped fluid, an inlet for the lubrication fluid provided at a first pressure, and a piston bore fluidly coupled to the inlet for the pumped fluid. The piston is moveable within the piston bore. The first annulus is fluidly coupled to the inlet for the lubrication fluid. The second annulus is configured to be fluidly coupled to a drain circuit provided at a second pressure less than the first pressure. The first annulus and the second annulus are located along the length of the piston bore.

摘要： A pressure relief valve includes a valve body having a valve seat fluidly positioned between an inlet and an outlet. A valve member is movable among a first position, a second position, and a third position. The valve member is in contact with the valve seat and fluidly blocks the inlet from the outlet at the first position. At the second position of the valve member, the inlet is fluidly connected to the outlet via a small flow area. The inlet is fluidly connected to the outlet via a large flow area when the valve member is at the third position. An electrical actuator is attached to the valve body and is operably coupled to move the valve member when energized. The valve member includes an opening hydraulic surface exposed to fluid pressure in the inlet when at the first position. A spring is operably positioned to bias the valve member toward the second position when the valve member is at the third position.
