    摘要： A fuel injector assembly for a fuel injection system has a fuel pumping assembly with a fuel inlet and a fuel nozzle for causing fuel to be periodically pumped from the fuel inlet through the nozzle. The fuel injector assembly has an electro-hydraulic control valve associated with the fuel pumping means. The control valve comprises a housing, a first conduit formed in the housing and fluidly coupled to the fuel pumping means, a second conduit formed in the housing and fluidly coupled to a source of pressurized hydraulic fluid. A valve element is disposed in the housing and is reciprocable between a first position in which the first conduit is fluidly coupled to the second conduit and a second position in which the first conduit is fluidly isolated from the second conduit. The control valve also includes a pair of electrically energizable electromagnetic devices for controlling the reciprocation of the valve element. The components of the control valve are preferably composed of SAE 52100 steel so that the valve element remains latched in the first and second positions after electric current to the electromagnetic devices is turned off.

    摘要： An improved hydraulically-actuated fluid injector system comprises a hydraulically-actuated fuel pressurization member, a fluid storage chamber, and a direct-operated check. Pressurization of fluid in the storage chamber begins before the start of fluid injection. Fluid injection begins by hydraulically unbalancing the check. Fluid injection ends by hydraulically balancing the check to allow a biasing device to close the check. Preferably, actuating fluid that is spilled from the fuel pressurization member (to end fuel injection) is communicated to a hydraulic motor which drives a source of pressurized hydraulically-actuating fluid. The present invention provides improved control of several fluid injection parameters, including higher peak fluid injection capability and less fluid injection pressure drop at the end of injection, resulting in improved engine performance and lower emissions, noise, and wear. The present invention also improves efficiency of operation due to the above hydraulic energy recovery feature.

    摘要： Use of pump and line fuel injectors has become more common in fuel injection systems. While these fuel injectors do not typically include individual electrical actuators or fuel pressurization means, they still include a number of components that must be intricately machined in order for the fuel injector to perform as desired. The present invention is directed to reducing the number of machining steps, and therefore the cost, of producing such a fuel injector by utilizing a plastic component that can allow for a reliable and cost effective replacement of more intricately machined fuel injector components.

    摘要： A solenoid actuator, adapted for use in an electronic control valve for a fuel injector, having an electrically-energizable electromagnetic device, such as a winding, a pole member associated with the electrically energizable winding, and an armature movable with respect to the pole member. The armature occupies a first position relative to the pole member when the winding is not electrically energized and a second position relative to the pole member when the winding is electrically energized. The actuator has an adjustment screw which is movable with respect to the pole member to form an air gap of variable width internal to the pole member to change the magnetic characteristics of the solenoid actuator, and thus the response of the actuator.

    摘要： A solenoid actuator, adapted for use in a fuel injector, has a pole member, an armature associated therewith, and an energizable winding associated with the pole member. The solenoid actuator is latchable by residual magnetism between the pole member and the armature without the aid of a permanent magnet. The pole member and the armature are composed of steel having a carbon content of between 0.8% and 1.2% and an RC hardness of between 40 and 60. The armature is reciprocable between a first position in which the armature makes physical contact with the pole member and a second position in which the armature is spaced from the pole member. The armature occupies the first position when the winding is energized and the second position when the winding is deenergized. The armature is held in the first position by residual magnetism between the pole member and the armature when the winding is deenergized after being initially energized. The actuator may also be embodied in the form of a dual-acting actuator having an armature and first and second pole members. The armature and pole member(s) of the actuator may be formed via a heat treating method which is based on the recognition of the relationship between the hardness of the pole member(s) and armature and the resultant residual magnetism of those components.
