An injector body defines a first set of nozzle outlets, a second set of nozzle outlets, a first fuel inlet and a second fuel inlet. A dual solenoid actuator includes a first armature, a first coil, a second armature and a second coil that share a common centerline. The dual solenoid actuator has a non-injection configuration at which the first armature is at an un-energized position and the second armature is at an un-energized position. The dual solenoid actuator has a first fuel injection configuration at which the first fuel inlet is fluidly connected to the first set of nozzle outlets, the first armature is at an energized position and the second armature is at the un-energized position. The dual solenoid actuator has a second fuel injection configuration at which the second fuel inlet is fluidly connected to the second set of nozzle outlets, the first armature is at the un-energized position and the second armature is at an energized position. The dual solenoid actuator may also include a combined fuel injection configuration.

摘要： A common rail single fluid injection system includes fuel injectors with one or two control valve assemblies with the ability to produce ramp, square and split injection rate shapes. This is accomplished by including a check speed control device disposed between a first and second check control chamber within a cavity defined by the injector body. The control valves and check speed control device control the speed of a check by controlling the flow of fuel out of the first and second check control chambers.

摘要： An improved fuel injector system comprising a nozzle tip which defines a pressure control chamber, an injection chamber, and at least one fuel injection orifice. The nozzle tip further includes a movable direct-operated check operable to selectively control fluid communication between the injection chamber and the fuel injection orifice. The improvement includes a hilt reciprocally movable within the injection chamber and being of a construction to define a lower chamber and an upper chamber. The improvement further includes a high pressure fuel passage communicating high pressure fuel to the lower chamber. The present invention provides reduced stresses on the nozzle tip as the check engages the check seat while not adversely affecting the performance of the fuel injector. This results in lower tip wear and improved life of the fuel injector.

摘要： A fuel control member of an internal combustion engine is operative to control the flow of fuel to the engine and is operatively connected to an element of a speed responsive governor which is adapted to urge the fuel control member towad an increased fuel position when the load on the engine is increased. A device is provided for limiting movement of the fuel control member toward the increased fuel direction establishing a maximum fuel flow position of the fuel control member. A speed sensitive flyweight arrangement is connected to the element of the governor for moving it and the fuel control member in a decreased fuel flow direction for reducing the amount of fuel delivered to the engine when the engine speed decreases below a predetermined speed due to a load thereon.
