Locking cylinder, in particular double locking cylinder with free-running locking element

摘要

The cylinder has a cylinder core coupled with a locking unit (6) by coupling elements (7, 8) during pushing of a key into a key channel, where the coupling elements are moved to a coupling position by a key tip. A coupling projection (9) of the coupling elements engages in a coupling recess (11) of the locking unit in the position. The coupling elements are moved from the position when the key is pulled by applying torque on the locking unit. A controller controls torque transmission edges (10, 12) of the projection and/or the recess for moving the coupling elements from the position.
