Abstract
In an apparatus for operating a valve element consisting of a base, an operating lever pivotally journalled with respect to the base and a drive apparatus which is secured to the base and engages the operating lever which has at least one of its ends for operating on the valve element, the drive apparatus comprises two piezo-electric transistors which are secured with a nonparallel orientation between the base and the operating lever such that they are each moveable relative to the base and the operating lever about an axis parallel to the pivoting or rocking axis of the operating lever.
