Disc tumbler cylinder lock and key combination

A disc tumbler cylinder lock and key combination, in which the disc tumbler cylinder lock comprises rotation limiting means, and the key comprises guidance surfaces for the rotation limiting means, which rotation limiting means comprise a frame, which comprises a key profile opening, and a casing, which at least partially surrounds the frame, wherein the frame comprises a limiting mechanism and a locking mechanism, which are disposed in a line such that the limiting mechanism is on one side of the key profile opening and the locking mechanism is on an opposite side of the key profile opening,

• which locking mechanism comprises a locking pin directed along said line, which locking pin comprises, at an end of the locking pin adjacent the casing, a projection that is transverse in relation to the axis of the locking pin, which projection is arranged, in cooperation with the casing, to prevent the frame from turning, when the key is not in the disc tumbler cylinder lock or not fully inserted into the disc tumbler cylinder lock,
• which key comprises a through hole, in which hole is disposed a moving element, which is arranged to move in the hole such that it is prevented from moving completely away from the hole, wherein the surfaces of the moving element form said guidance surfaces,
• in which combination, when the key is in the disc tumbler cylinder lock for the purpose of opening the lock, the through hole and moving element are in the same line with the limiting mechanism and the locking mechanism, and which limiting mechanism is arranged to push the moving element out of the hole onto the opposite side of the key profile opening, and to allow turning of the key, and which locking mechanism is arranged, in response to the pushing of the moving element, to release a barrier formed by the cooperation of the casing and the projection of the locking pin.
