  • the control element 54 then projects radially inwards into the circumferential recess 108 at a defined angular position front lift disc 48 is urged (see. Fig. 17 ).
  • the angular position of the disk housing 14 can be defined with particularly high accuracy, in which (for the subsequent unlocking) the disk housing 14 is decoupled from the cylinder housing 12 and coupled to the front lifting disk 48 (and thus to the key 24).
  • FIGS. 18 and 21 show the locking pin 22 until it reaches the unlocked position in contact with the locking pin receiving recess 74 in unlocking D limiting Sperrlochers.

Fig. 1 ) and thereby the shims 16 relative to each other and fixed to the disc housing 14, and that only then (due to still further rotation of the disc housing 14) of the locking pin 22 penetrates into the locking recesses 20 to the disc housing 14 for another Turning to release in the unlocked position.
  • the front Ausheberance 48 has on its outer periphery a second stop 120, the reverse rotation of the front Ausheberance 48 from the sorting end position (see. Fig. 14 ) against the unlocking direction D, ie in the locking direction, upon reaching the zero position in contact with a provided on the disc housing 14 second counter-stop 122 passes (see. Fig. 11 ).
  • a corresponding stop is also provided on the rear Ausheberance 50.
