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.
