A rekeyable cylinder (1) comprising a stator (2) provided with a substantially cylindrical receptacle (3) for a rotor (4). The rotor (4) and the stator (2) are affected by channels (5) for at least one respective pin, movable so that it can slide in them in contrast to respective elastic means. The simultaneous arrangement of the pins partly in the rotor (4) and partly in the stator (2) determines the locking of the rotor (4), and the alignment of a terminal edge of the pins with the interface surface between stator (2) and rotor (4), obtained through the insertion of an adapted key (7) with a contoured profile into an opening (6) of the rotor (4) that faces the channels (5), determines the free rotation of the rotor (4) with respect to the stator (2). At least one of the pins is constituted by a pair of substantially complementary valves (9, 1 1) which are provided, along at least one respective mutual coupling surface, with at least one respective profile (10), the first valve (9), and with at least one corresponding counter-profile (12), the second valve (1 1). The first valve (9) can perform a translational movement with respect to stator (2) and rotor (4), and the second valve (1 1) can perform a translational and rotational movement, along a preset angular stroke, with respect to stator (2) and rotor (4). The second valve (1 1) comprises abutment means for a specific utensil (13) pertaining thereto through an auxiliary duct (14) of the rotor (4) that faces the abutment means. |
