The mechanism comprises a locking member (7) which moves along with adjusting element (3) and locking member (8) which is rigidly connected to a housing of the valve. The two locking members are made up of two disc-shaped elements, which comprise opposing boundary surfaces extending transversely to the axis of rotation. The locking member (8) is suspended from the disc shaped element which is connected to the adjusting element. The members can be locked against rotation relative to each other by arms (11) cooperating with strip shaped parts (12) mounted on housing. |
