The device has rocker arm carriers (16), torsion springs (18), a rocker arm (20) and a plate spring (22) embracing an annular flange (24) of an aperture of a nozzle (10) in a closure position such that a nozzle closure body (12) closes the nozzle. A lockbolt (26) and a stop unit (28) are moved between a blockage position and a releasing position. The lockbolt and the stop unit block and release the carriers, the springs and the arm in the closure- and releasing positions, so that the nozzle closure body is removed from the nozzle. A rope or cable (30) moves the lockbolt and the stop unit. |
