  • Patent number: 7431263
    Abstract: A solenoid arrangement includes an electromagnetic valve device having a coil disposed in a casing, and a movable armature slidably received in the coil for allowing the movable armature to be actuated by the coil to move relative to the coil and the casing, the casing includes a sleeve having a bore for slidably and changeably receiving shanks of different lengths which may be attracted to the movable armature for being moved in concert with the movable armature. The electromagnetic valve device may be adjusted to different moving strokes with different shanks for attaching or coupling to different operating facilities that require different moving strokes.
