Zusammenfassung:	A device for controlling the opening and closing movement of a duct seal door of an automatic ice maker which requires a regulator for slowing down the closing of the door. The movement of the door about its rotational axis is transmitted via connecting linkages to the closure regulator which comprises a rotor positioned within a stator housing. The rotor's movement is coupled to the connecting linkages via a one-way clutch which decouples the rotor when the door is being opened, and causes positive coupling therebetween when the door is being closed. Disposed within the stator housing in a fixed-volume compartment is a viscous fluid, such as silicone gum. The rotor and stator include opposed rippled surfaces between which the viscous fluid is coactively disposed. The fluid acts as an impedance to the motion of the rotor, which motion occurs only upon the closing of the door, to thereby provide a controlled slow closure thereof.
