Patent ID: 8656746

Claim:
A lock cylinder comprising a cylinder housing ( 12 ); a cylinder core ( 14 ) rotatably supported about a cylinder axis in the cylinder housing ( 12 ); at least one locking pin ( 22 ) which is provided at the outer periphery of the cylinder core ( 14 ), which is aligned parallel to the cylinder axis, which can be displaced radially to the cylinder axis, which blocks the cylinder core ( 14 ) against a rotational movement in a radially outer blocking position and which releases the cylinder core ( 14 ) for a rotational movement in a radially inner release position; a plurality of tumbler disks ( 16 ) arranged along the cylinder axis in the cylinder core ( 14 ) and rotatably supported between a latch position and an unlatch position, wherein each tumbler disk ( 16 ) has a central reception opening ( 18 ) for receiving a key ( 24 ) and at least one peripheral cut-out ( 20 ) for receiving the locking pin ( 22 ) in the release position, wherein the locking pin ( 22 ) can only be displaced into the release position when all the tumbler disks ( 16 ) are in their unlatch position in which the peripheral cut-out ( 20 ) of the respective tumbler disk ( 16 ) is aligned radially to the locking pin ( 22 ); and a plurality of intermediate disks ( 136 ) arranged along the cylinder axis in the cylinder core, wherein a respective intermediate disk ( 136 ) is arranged between two mutually adjacent tumbler disks ( 16 ), and wherein the intermediate disks ( 136 ) have a predefined rotational clearance (S) relative to the cylinder core ( 14 ) while the locking pin ( 22 ) is in the radially outer blocking position.
