Abstract
A device for controlling a central shutter, in which a plurality of shutter leaves () are mounted on a circularly annular leaf carrier () such that they can be pivoted on a pivoting arm (), and in which, as actuating device for the pivoting movement of the shutter leaves (), an annular cam plate () is mounted on the leaf carrier () concentrically with respect to the shutter opening (), such that it can be rotated continuously in one direction, it being possible for the rotation of the cam plate () to be blocked by mechanical engagement into a cam trough () in front of an actuating flank () of a cam, is distinguished by the fact that, for mechanical blocking purposes, there is a push rod () of a solenoid, which push rod () can be moved perpendicularly with respect to the plane of the cam plate ().
