Abstract
The invention relates to a cylinder lock of the type of a disk tumbler cylinder having a cylinder housing and a cylinder core rotatable therein, with a plurality of blockable disk tumblers being provided in the cylinder core which have at least one respective engagement section. The disk tumblers are movable between an unlatched position and a latched position and are biased along a respective direction of bias into the latched position. In the latched position, the respective engagement section engages into an associated cut-out in the cylinder housing to block the cylinder core against a rotary movement relative to the cylinder housing. The cylinder core is rotatable in a rotary opening direction relative to the cylinder housing when the disk tumblers are in the unlatched position. At least one of the disk tumblers has a toothed zone which can be brought into engagement with a counter-toothed zone of the cylinder lock such that the disk tumbler is blocked against a movement opposite to the respective direction of bias when the disk tumbler is in the latched position and a torque is exerted onto the cylinder core in the rotary opening direction.
