Abstract: An electromagnetically operated valve, comprises a valve slide with a magnet armature, which is equipped to close a sealing seat in a fluid channel of the valve with a first axial end in a closed position, as well as a sealing element with folded bellows situated between the sealing seat and the first axial end of the valve slide and separates the valve slide from the fluid channel with a fluid-tight seal. The magnet armature is supported in the valve in an essentially non-contact manner due to the fact that the valve slide has a guide pin protruding in the axial direction from the magnetic armature on a second axial end opposite the first axial end, the guide pin being supported to slide in the axial direction; and the valve slide is aligned in the radial direction on a side of the magnet armature facing the first axial end of the valve slide and is supported so it is movable in the axial direction by means of at least one spring element.

Abstract: 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.

Abstract: An electromagnetically or electrically operated valve possesses a closing element that is axially displaceable between a closed position and an open position. The closing element is pressure-compensated, by the pressure present on the front side of the closing element being passed to the back side thereof. Between the front and back sides the closing element is sealed radially against a surrounding structural element by means of a dynamic seal. The circumferential sealing gap varies in width in dependence on the axial position of the closing element, so that the dynamic seal seals reliably only in the closed position, while in other positions the static friction of the dynamic seal is reduced.

Abstract: A valve body arrangement for a hydraulic or pneumatic valve comprises two elements between which a valve body is retained. The two elements are welded together in a first region, preferably by the laser transmission method, and clamp the valve body in a second region with a force.

Abstract: The invention relates to a directly controlled magnetic valve, comprising a fixed core which is located in a magnet and a moving armature to which a seal plate is fixed by means of a tappet. When the valve is activated, the seal plate interacts with a valve seat which is fixed to the housing. Corresponding sealing elements are provided on the seal plate and on the valve seat and at least the tappet and the seal plate have bores which are situated centrally in the longitudinal direction. The aim of the invention is to produce a magnetic valve which has a large nominal width allowing a small construction volume, a low power requirement, rapid pressure compensation and rapid switching. To this end, second sealing elements which correspond with each other are provided on a front face which is permanently connected to the armature and on an adjacent face which is fixed to the housing.
