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.
