<p>An electromechanical lock cylinder is disclosed. The lock cylinder, which interacts with evaluating electronics for recognizing an access authorization and comprises a housing that has two opposing cylindrical cavities (12). A lock core, which can be actuated by a key, or a knob shaft (11), which is joined to a knob in a rotationally fixed manner, is rotationally mounted in the cavities. The lock core and/or knob shaft (11) interact with a lock lug (13), which actuates, in particular, a bolt or latch of a door lock. When the key fits or in the event of a successful access authorization, an electromechanically driven blocking or coupling element (14) is moved out of the position of rest and into an angular position, and a rotationally fixed joining between the key or knob and the lock lug (13) is effected. The invention is characterized in that, when the blocking or coupling element (14) is in a position of rest, the lock lug (13) can be freely rotated relative to both lock cores or to both knob shafts (11).</p> |
