(54) Lock cylinder having two driving elements coupled rotatably together


(57) The invention relates to a lock cylinder (1) having two driving elements coupled rotatably together, one of which in the form of a sleeve (7) encases the other in the form of a core (6). The two driving elements are coupled to one another by a latch (8) that is arranged in the core (6), is spring-mounted in a radially outward direction with respect to the core, and engages in an opening (9) in the sleeve (7). The coupling is releasable by engagement of a tool in a radial opening (18) arranged in alignment with the latch displacement direction. The latch (8) is arranged to be displaced backwards into a latch deflection space (17). The radial depth of the latch deflection space (17) is greater than the back-travel of the latch (8) required for disengagement. The plurality of latches (8) operate independently of one another and are arranged in a common cross-sectional plane.
