ABSTRACT:
A valve features a deflectable actuating element (1) that controls the movements of at least one actual sealing element (3) for opening and/or closing at least one sealing contour (6), and the actuating element is loaded via an elastic element (5) essentially perpendicularly relative to the direction of the deflection; and the longitudinal axis of the actuating element and the force applied by the elastic element are aligned in a position of the actuating element that is between its two extreme positions. The actuating element (1) is preferably an unilaterally loaded piezoelectric bending transducer, and the sealing element (3) is preferably a toggle that has the ability to swing around an axis arranged perpendicularly relative to the direction of the deflection of the actuating element (1).
