Abstract

The lock cylinder has a rotary lever which is mounted on the lock cylinder housing (1), so that it normally rotates freely, and is coupled to a locking member if an appropriate key is detected. A brake rotates with the lever and suppresses the rotation of the lever when the rotation speed of the lever exceeds a limit speed. The brake is preferably a centrifugal brake. An independent claim is included for a lock cylinder.
