摘要： Starting and ending an injection event are accomplished by respectively energizing and de-energizing a solenoid actuator to move an armature assembly with respect to a stator. The stator is protected from impact damage by maintaining the armature assembly out of contact with the stator. The inducement of residual magnetism in the armature assembly is reduced by stopping the armature assembly at a large radius outside of the magnetic flux circuit through the stator and soft magnetic armature of the armature assembly, when the solenoid actuator is energized.
摘要翻译：通过分别对螺线管致动器通电和断电以相对于定子移动电枢组件来实现启动和结束喷射事件。通过保持电枢组件与定子不接触，保护定子免受冲击损坏。当螺线管执行器通电时，通过电枢组件的定子和软磁衔铁将电枢组件停在磁通回路外部的大半径处，可以减少电枢组件中剩余磁力的诱导。

摘要： In one aspect, a fuel injector includes an injector body that defines a fuel inlet, a drain outlet and a nozzle outlet. A direct operated check valve is positioned in the injector body and includes a needle valve member with an opening hydraulic surface exposed to fluid pressure in a nozzle supply passage, and a closing hydraulic surface exposed to fluid pressure in a needle control chamber. The needle valve member is movable between a first position at which the nozzle supply passage is blocked to the nozzle outlet, and a second position at which the nozzle supply passage is open to the nozzle outlet. A needle control valve is positioned in the injector body and includes a control valve member movable between a first position at which the needle control chamber is fluidly connected to the drain outlet, and a second position at which the needle control chamber is fluidly blocked to the drain outlet. A solenoid actuator is positioned in the injector body and includes a stator assembly and an armature assembly coupled to the control valve member. One of the stator assembly and the armature assembly includes a non-magnetic insert that moves into and out of contact with another of the stator assembly and the armature assembly at an energized position and a de-energized position, respectively.

摘要： An efficient control wave form is utilized to actuate the solenoids of a fuel system to reduce boost power/energy consumption. The solenoid is initially energized by applying a boost voltage from an electronic controller across a solenoid coil circuit. The electronic controller monitors the current level in the solenoid coil circuit, and changes to a reduced battery voltage when the current level in the solenoid coil circuit reaches a predetermined trigger current. The controller then maintains a pull-in current based upon battery voltage for a pull-in duration that initiates movement of the solenoid armature from an initial air gap position toward a final air gap position. After the pull-in duration, the current level is dropped to a hold in level for the remaining duration of the actuation event. The solenoid may be used for fuel injector control and/or pump control, such as to control fuel injection and pumping events respectively.

摘要： An apparatus and method for controlling fluid flow is disclosed. An electromagnetic actuator may include a stator having an inner pole member and an outer pole member. The outer pole member may have a fluid passageway therein for transmitting fluid through the outer pole member. The actuator may further include a coil disposed around the inner pole member and arranged between the inner pole member and the outer pole member. The actuator may also include an armature moveable under the influence of a magnetic field generated by the stator and coil and operable to affect transmission of the fluid through the fluid passageway.
