<p>The invention relates to disc cylinder lock-key-combination, including a cylinder housing (1), and inside thereof, a turnable inner cylinder (2), which encloses a set of discs comprising a number of locking discs (3,4) provided with peripheral notches (8) and separated from one another by means of intermediate discs (5), and a locking bar (10), which in the locked position of the lock is located partly in a groove in the cylinder housing and partly in a slot (9) in the inner cylinder thereby preventing the inner cylinder to be turned with regard to the cylinder housing. The locking discs (3,4) are turnable by means of the key (12) of the lock into a position, in which the peripheral notches (8) form a uniform channel at the position of said slot (9) of the inner cylinder, into which channel the locking bar (10) can enter from the groove of the cylinder housing thereby releasing the inner cylinder to turn with regard to the cylinder housing. In accordance with the invention a guiding element (18), cooperating with the key (12) and extending at least substantially across the axial length of the set of discs, is arranged in the keyway formed jointly by the key openings (6,7) of the discs (3,4,5) in the set of discs. The lock includes further at least one member (3,23) turning continuously with the key when the key is turned in the lock, to which member the guiding element (18) is supported and from which the guiding element (18) is arranged to receive its guidance.</p> |
