Abstract
A locking unit for the locking of the movement of a piston. An electromagnet is provided the armature, respectively the armature bar, of which acts on an operating element. The operating element co-operates with a catching element in such a way that the catching element blocks in a locking position the movement of the piston, respectively the catching element unlocks in an unlocking position the movement of the piston. Catching element and operating element co-operate surface-to-surface.
Claims24
Locking unit for locking of movement of a piston which can be impinged with pressure, said locking unit comprising
- a piston,
- an electromagnet provided with an armature bar acting on an operating element, said operating element cooperating with a catching element of the piston in such a way that, in a locking position of the pistons, the catching element blocks continued movement of the piston, and, in an unlocking position of the piston, the catching element allows movement of the piston,
- the catching element and the operating element co-operate surface to surface by axial movement toward and away from each other,
- a bolt on the armature bar, the bolt acting through movement of the armature bar on the operating element, and
- at least one tapered beveling of the bolt co-operating with a conical inwardly extending projection of the operating element by slidingly engaging the at least one tapered beveling of the bolt with the conical inwardly extending projection of the operating element during movement of the armature bar to release the operating element from engaging the catching element and preventing movement of the piston,
- the conically inwardly extending projection being located between the catching element and the electromagnet.
Locking unit for locking of movement of a piston which can be impinged with pressure, said locking unit comprising
- an electromagnet provided with an armature bar acting on an operating element, said operating element cooperating with a catching element in such a way that, in a locking position of the piston, the catching element blocks movement of the piston, and, in an unlocking position of the piston, the catching element releases the movement of the piston,
- the catching element and the operating element co-operate surface to surface by axial movement toward and away from each other,
- a bolt on the armature bar, the bolt acting through movement of the armature bar on the operating element, and
- at least one tapered beveling of the bolt co-operating with the operating element by slidingly engaging the operating element during movement of the armature bar,
- the electromagnet having a coil through which current flows and the armature bar moving against the power of a spring.

- the catching element and the operating element co-operate surface to surface by axial movement toward and away from each other,
- a bolt on the armature bar, the bolt acting through movement of the armature bar on the operating element, and
- at least one tapered beveling of the bolt co-operating with the operating element by slidingly engaging the operating element during movement of the armature bar, the armature bar sitting close on the piston in the locking position supported by a spring.
