Abstract
A flap is pivotally mounted on a roller that runs in a track; a three point control lever has one point connected to the roller, a second point to the front of the flap, and a third point is variably connected to a turning lever that drives the flap. The variation is obtained either by providing a secondary lever on the turning lever to obtain a cycloidal path, or a spindel drive just varies the distance between the third point of the control lever and the axis of the turning lever. The turning lever is hollow to accommodate the drive elements for the third point variation.
