Method of blocking a translation movement by clipping a rotor in a lock stator and rotor front part

摘要

The method involves housing an open snap ring (2) in an annular groove of a stator (4) by a retaining part (3A) of a trigger (3). The snap ring is released by elastic deformation in another annular groove of a cylinder of a rotor (5) by pushing the retaining part in the direction of a longitudinal axis of the stator when the snap ring is in opposite to the latter annular groove. Independent claims are also included for the following: (1) a front part or rotor cylinder for implementing a rotor blocking method (2) a rotor rear part cooperating with a rotor front part (3) a lock comprising a stator.
