    摘要： An electromagnetic fuel injection control valve positioned inside a fuel injector, i.e. a unit injector, for providing fast response and high pressure capability while minimizing the size and complexity of the injector. The control valve includes a valve housing having a supply inlet and fuel outlet, a center tube having a center passage and an annular valve seat, a control valve sleeve slidably mounted on the center tube and an actuator assembly having a coil spring, a stator and an armature. The control valve sleeve moves between an open position permitting fuel to flow between the supply inlet and the fuel outlet and a closed position which sealingly engages the annular valve seat for blocking the flow of fuel between the supply inlet and the fuel outlet. The coil spring biases the control valve sleeve in an open position and is positioned around the center tube. The stator is also axially positioned around the center tube and includes multiple poles. The armature connects to the control valve sleeve and reciprocates when solenoid is activated to allow for high pressure fuel injection into the combustion chamber of an internal combustion engine.

    摘要： A compact fluid flow control valve is provided which effectively and predictably controls the flow of fluid using a minimum number of components to permit inexpensive manufacture and assembly. The control valve includes a one-piece valve plunger guide and stop which extends through an aperture formed in a stator of the solenoid assembly. The valve plunger guide and stop includes an integral guide surface for guiding the valve plunger through reciprocal movement within the aperture of the stator, an integral stop surface positioned for abutment by the valve plunger when in the energized position to define a minimum air gap between an armature and the stator. The one-piece valve plunger guide and stop reduces the number of parts of the control valve to achieve simplicity in structure and lower costs while avoiding the need for a shim to set the minimum air gap. The present control valve also includes a plunger overtravel impact limiting device including a movable valve head and a hydraulic damping device. The hydraulic damping device includes a fluid passage formed between a portion of the valve plunger assembly and the valve housing. The velocity of the valve plunger assembly is substantially decreased as the valve plunger assembly squeezes fuel from the fluid passage during movement of the valve plunger toward the closed position. The plunger overtravel impact limiting device effectively reduces valve seat wear and valve bounce.
