摘要

An actuator device (1) for operating a shut-off member (12) for an air duct (8) in a refrigerator (5) of forced air circulation type, said duct (8) opening via an aperture (7) into a freezer compartment or refrigeration compartment (3), at said aperture (7) there being provided preferably a grille able to be closed by a shutter member (12) which is movable relative to the grille (11) along usual guides (13). The shutter member (12) cooperates with a drive means (16) for moving said shutter (12) along said guides (13), and with retention means (25) for retaining said shutter (12) at least in the position in which it completely closes said aperture (7), said retention means (25) releasing said shutter (12) to enable it to move when said aperture (7) is to be opened. <IMAGE>
