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： A fuel system for an engine is disclosed. The fuel system may have a pump, a plurality of fuel injectors, and a plurality of fuel accumulators. Each of the plurality of fuel accumulators may be disposed at least partially within a different cylinder head of the engine in fluid communication with an associated fuel injector of the plurality of fuel injectors. Each of the plurality of fuel accumulators may also be in fluid communication with adjacent fuel accumulators of the plurality of fuel accumulators. At least one of the plurality of fuel accumulators may also be in fluid communication with the pump. The fuel system may further have a plurality of flow limiters. Each of the plurality of flow limiters may be disposed between an associated fuel accumulator of the plurality of fuel accumulators and an associated fuel injector of the plurality of fuel injectors.

摘要： A two-piece assembly having both a plug component and a load component. The plug component includes a protrusion or bite edge that is capable of creating a metal-to-metal seal. The load component is rotated into position such that it provides an axial force on the plug component and increases the quality of the metal-to-metal seal. Rotational force from the load component is not transferred to the plug component because of a zero-moment interface. Thus, the present sealing assembly is capable of sealing at high pressures and avoid creating leak paths in the sealing land.
摘要翻译： 具有插头部件和负载部件的两件式组件。 插头部件包括能够形成金属对金属密封件的突起或咬合边缘。 负载部件旋转到位置，使得其在插塞部件上提供轴向力并且提高金属对金属密封件的质量。 由于零力矩接口，来自负载组件的转动力不会传递到插头组件。 因此，本密封组件能够在高压下密封，并避免在密封区域中产生泄漏路径。
