Valve with unilaterally constrained piezoelectric bending element as actuating device
First Claim
1. A valve with a displaceable actuating device (1) which controls the movements of at least one actual sealing device (3) for opening and closing, and the actuating device is loaded by an elastic element (5) essentially in a perpendicular direction relative to the direction of displacement, and the longitudinal axis of the actuating device and the force that is exercised by the elastic element are aligned in one position of the actuating device between its extreme positions wherein the actuating device (1) is realized as a unilaterally constrained piezoelectric bending element.

Abstract
Valve with a displaceable actuating device that controls the movements of at least one actual sealing element for opening and closing, and the actuating device is loaded with an elastic element essentially in a perpendicular direction relative to the direction of displacement, and the longitudinal axis of the actuating device and the force exercised by the elastic element are aligned in one position of the actuating device between its two extreme positions. In order to realize a valve that can be electrically switched using minimal currents and that is characterized, in particular, by its small construction size but that is still able to achieve large regulating distances, the actuating device is a unilaterally constrained piezoelectric bending element.
