Abstract

The invention refers to a locking unit for locking the movement of a piston drivable by a drive. The locking unit comprises a solenoid and a catch assembly. The catch assembly has a spring section and a latch section, wherein the elastic spring section angles the catch assembly against an armature rod. In a locking position, the latch section blocks the movement of the piston. In an unlocking position, the movement of the piston is released. The latch section is equipped at least with a reinforcement acting in the direction of movement of the piston.
