Abstract
A drive cartridge comprises an actuating mechanism, in which a spindle can be guided in a hollow cylindrical drive element between two end positions at an axial distance from one another. The positions are defined by the axial length of the drive element. A dome-shaped casing surrounds the drive element in a non-rotatable and non-displaceable manner. The drive element has an external contour with an eccentric profile and the internal contour of the dome-shaped casing has a positive fit only in those areas of the drive element in which the permissible normal stress exceeds a predefined upper limit.
