Abstract
A lock cylinder having: a cylinder core having a key channel for inserting a key which is provided with profiling; at least one feeler element which is disposed in the cylinder core, is acted on by a spring and is held in a blocking position by the spring when the key is not inserted in the key channel; and a blocking element which, when the feeler element is in the blocking position, is held in a blocking position which blocks rotation of the cylinder core. The feeler element can be shifted against the return force of the spring into a release position by the profiling on the matching key inserted into the key channel, in which position the locking element can be deflected into a position releasing the cylinder core. In order to enable the lock cylinder to lock more securely, the feeler element includes a feeler arm for feeling the profiling, which feeler arm protrudes radially from a shaft rotatably supported in the cylinder core and which feeler arm, when the matching key is inserted, is acted upon such that the shaft rotates about the axis thereof into the release position.
