    摘要： An electromagnetically actuated piston slide valve includes a piston slide arrangement with a piston which is axially displaceable for regulating a free cross section of a fluid passage of the valve. The piston slide arrangement contains a first magnetic armature connected to the piston and a second magnetic armature which is axially displaceable with respect to the piston. The piston is axially displaceable against the force of a first biasing spring by generating an electromagnetic field through energizing a coil. A second biasing spring rests against the first magnetic armature and the second magnetic armature, so, in the unenergized state of the coil, the piston takes a predetermined position by axial displacement due to the force of the first biasing device against the force of the first biasing device. A permanent magnet generates an attractive force between the first and the second magnetic armature which counteracts the second biasing spring.

    摘要： A linear actuator for an active engine mount of a vehicle has a stator with a coil that can be fed with electric current for generating an electromagnetic field and an actuating element that is mounted in axially movable fashion with reference to the stator. The actuating element comprises an armature and a ram extending in axial direction and is so mounted in the stator by means of at least one spring element that it can be moved axially in frictionless fashion when the coil is fed with current. The actuating element comprises a support element of a non-magnetic light-weight construction material extending in radial direction between the armature and the ram. Advantageously, the armature is provided only in such regions where there run magnetically relevant field lines of the electromagnetic field of the coil.

    摘要： An electromagnetically actuated piston slide valve and an assembly set for such a valve with which an NC valve and an NO valve can be fabricated. Such a valve of the NC construction type comprises a valve housing with corresponding connectors and a fluid passage. A slide coupled with a magnetic armature is provided for regulating a free cross-sectional area of the fluid passage. A first spring urges the slide in an opening direction and a second spring urges the slide in an opposite closing direction, wherein the first and the second spring are adapted such that, in the electrically unenergized state of the coil, the slide adopts a position in which the fluid passage is closed.

    摘要： A linear actuator for an active motor mount of a motor vehicle includes a stator which has an electrically energizable coil for generating an electromagnetic field, as well as a magnetic armature which is mounted axially movable with regard to a longitudinal axis of the coil and has at least one permanent magnet ring which opposes the stator and has several permanent magnet ring segments. Between a surface of the permanent magnet ring segments which faces the stator and a surface of the stator which faces the permanent magnet ring segments there exists an angular gap with a gap angle (α) of preferably 4°.

    摘要： An electrically or electromagnetically operated valve has a movable structural group with a magnetic armature, which is movable along an axis between a first and a second position to open or close the valve. The valve has a valve sleeve in which the magnetic armature is movable between the first and the second position, the magnetic armature defining on its axial sides two volumes in the valve sleeve. There is provided a throttling element elastic in the radial direction, which is arranged between the first volume and the second volume such that upon axial movement of the movable structural group it throttles an air stream between the first volume and the second volume in order to decelerate a movement of the movable structural group.
