  • Flexural element for positioning an armature in a fuel injector
    Patent number: 6601784
    Abstract: A fuel injector includes a flexural element connected to a valve armature for restricting radial movement of the armature within a fuel passage. The flexural element is flat and exerts no force on the valve when it is closed but is flexed when the valve is opened and supplements the valve spring force during closing of the valve. The flexural element also is used to set the valve stroke length equal to the element's thickness. A flat tool presses a valve ball into the armature while the ball is seated on a valve seat until the flexural element engages a seat related surface. Engagement of the tool with the flexural element fixed to the armature assures that the flexural element is in an unloaded flat position when the valve is closed and establishes the valve stroke when the valve assembly and seat are installed in the injector body.

  • Anti-theft steering lock
    Patent number: 6598393
    Abstract: A system for steering the wheels of a vehicle. The system includes a steering gear provided with a steering rack reciprocable in a power cylinder. A steering shaft has a pinion meshing with the steering rack. A hydraulic fluid system assists the reciprocation of the steering rack. The hydraulic fluid system includes a power piston reciprocable in the power cylinder. A control valve directs hydraulic fluid from a pump to the power cylinder at one side or the other of the piston, depending on the direction of rotation of the steering shaft. A lock valve is operable when closed to lock the rack against reciprocation to prevent steering of the wheels by preventing fluid flow in the hydraulic fluid system. The lock valve is controlled by a solenoid-operated electronic controller.

  • Solenoid valve with cushion between plunger and plunger stop
    Patent number: 6595485
    Abstract: A solenoid valve includes an outlet tube and a plunger stop. A plunger is slidably disposed within the solenoid valve between the outlet tube and the plunger stop. The plunger is movable between a closed position wherein the plunger engages the outlet tube to block fluid flow there through and an open position wherein the plunger is distanced from the outlet tube to permit fluid flow there through. The plunger includes a plunger insert that forms a dome-shaped plunger stop cushion that, during opening of the valve at least partially contacts a flat plunger contact face formed by the plunger stop. The dome-shaped plunger stop cushion relatively effectively damps the impact between the plunger and the plunger stop by allowing the plunger insert material, e.g., rubber, to compress more and absorb more energy of the impact. Thus, signal noise caused by the solenoid valve is minimized.
