Patent ID: 7926334

Claim:
A variable nozzle device coupled with an actuated member ( 12 ) to be actuated by an actuator ( 11 ) characterized by a tamperproof and calibration device ( 1 ) connecting the actuated member ( 12 ) with the actuator ( 11 ) for calibration of the relative position of the actuated member ( 12 ) of the variable nozzle device with respect to a predetermined position of the actuator ( 11 ), the tamperproof and calibration device ( 1 ) comprising: an adjusting member ( 4 ) for adjusting the position of a first element ( 15 ) in respect to a second element ( 3 ) in a first direction, the adjusting member ( 4 ) rotatably supported in the second element ( 3 ) and threaded on the first element ( 15 ); and a fixing member ( 5 ) that acts for fixation of the position of the first element ( 15 ) with respect to the second element ( 3 ), the fixing member ( 5 ) directed in a second direction that differs from the first direction.
