Abstract

The locking cylinder unit (20) includes a cylinder (21) and a piston (22), engaged with a spindle (35) by a non-self-locking thread (37). The spindle has at least one locking recess (38) containing a sprung locking body for locking bolts to engage in them. Several locking bodies are made in the form of separate movable locking bolts.
