摘要： A fuel filtration system is provided. The fuel filtration system includes a pump configured to receive a flow of fuel from a fuel storage tank and at least one filter positioned downstream to the fuel filtration system and fluidly coupled to the pump. The fuel filtration system further comprises a recirculation loop configured to recirculate at least a portion of the fuel through the at least one filter. The recirculation loop is also configured to provide a remaining portion of the fuel to an engine during the recirculation. The remaining portion of the fuel is determined based on a fuel consumption of the engine.

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： 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 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.

摘要： Although modern diesel fuel formulations are intended to reduce emissions of diesel engines, at least some of those modern fuels tend to have relatively low lubricity levels. The control valve assemblies described herein help to minimize any increased wear that would otherwise result from the use of such low lubricity fuels by providing a valve element, a valve guide, and an insert. The valve element is received within the valve guide and is moveable between an open position and a closed position. The insert forms a first sealed interface and a second sealed interface with the valve element and the valve guide. When the valve element is in the closed position, both of the first sealed interface and the second sealed interface are engaged. When the valve element is in the open position, only one of the first sealed interface and the second sealed interface is engaged.

摘要： A high volume high pressure common rail pump for a fuel system includes pairs of pump head assemblies in phase with each other but oriented in opposition to one another about a rotating cam shaft. Pump pistons in the pump head assemblies simultaneously undergo pumping strokes via a shared two lobe cam of the rotating cam shaft. The pump may include two pairs of pump head assemblies, and each head assembly may include two pump pistons. The cam shaft includes two cams sufficiently out of phase with one another that the cam shaft always has a positive torque even when the cam lobes are symmetrical. In addition, because the pumping is done simultaneously on opposite sides of the cam shaft, the forces on the cam shaft are balanced and its support bearings experience less wear and tear.
