Abstract (en)

[origin: EP0571172A1] A lock cylinder has resilient plate tumblers (8) which are arranged in the rotatable cylinder core (1) and project beyond the rotary joint (F) between the cylinder core (1) and the cylinder housing (3) into chambers (10) of the cylinder housing (3) in the checking position of the cylinder core (1). For achieving release of the cylinder core (1) for rotation thereof, the tumblers (8) may be set by indentations (7) of the key (6) into a position in which the plate tumblers (8) no longer protrude beyond the rotary joint (F). Removal of the key is checked when the key (6) has been turned, by axial shifting of the cylinder core (1) in the cylinder housing (3) such that the end face (19) of at least one plate tumbler (8) passes below a chamber wall (20) of the cylinder housing (3) blocking displacement of the plate tumbler (8) beyond the rotary joint (F). <IMAGE>
