Lock cylinder

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), wherein the intermediate disks (136) have a predefined rotational clearance (S) relative to the cylinder core (14), and
• wherein a predefined number of possible different codings is provided for the tumbler disks (16), with each of the codings being defined by a specific angular position of the peripheral cut-out (20) of the tumbler disk (16) with respect to the central reception opening (18), with the rotational clearance (S) of the intermediate disks (136) corresponding to the smallest angular spacing between the latch position and the unlatch position of the tumbler disks (16) with respect to the different possible codings.

• wherein each intermediate disk (136) has a peripheral cutaway (138) adapted to receive the locking pin (22) in its release position independently of the angular position of the intermediate disk (136), and
• wherein the angular dimension of the peripheral cutaway (138) of the respective intermediate disks (136) corresponds to at least the sum of the angular dimension (T) of the peripheral cut-outs (20) of the tumbler disks (16) and the rotational clearance (S) of the respective intermediate disk (136).
