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 pump manifold pressure control system may be effective to provide a compact and more effective fuel pump mechanism for compression ignition engines, such as diesel and some natural gas engines. The fuel pump manifold pressure control system includes a fuel pump manifold, at least one fuel injection accumulator adapted for supplying pressurized fuel to at least one fuel injector, a pressure control valve, a pressure sensor, and a pressure relief valve, all contained within a compact fuel pump housing. The pressure control valve and pressure sensor are each adapted for signal communication with electronic controller, and for fuel communication with the fuel pump manifold. The pressure relief valve is adapted for fuel communication with the fuel pump manifold. Each of the control valve, sensor, and relief valve are fixedly mounted to and internally contained within the housing.

摘要： A quill tube is provided. The quill tube includes a hollow body and a spherical head. The hollow body defines a bore within the quill tube. The bore is configured to direct a flow of fuel into a fuel injector. The spherical head is located at a first end of the hollow body. The spherical head includes a tip, a first surface and a second surface. The tip is located at a distal end of the spherical head. The first surface is configured to engage with the fuel injector. The second surface is positioned between the tip and the first surface. Further, a flange is located proximate to the spherical head. The flange is angularly positioned relative to the first surface. If the spherical head is contacted against an external surface, the flange is configured to cause the second surface to touch the external surface.
