ABSTRACT:
A fuel injection valve wherein a reciprocable valving element is movable from closed to open position by a piezoceramic moving unit having at least two flexural resonators in the form of laminated packages of metallic carriers, ceramic layers and foil-shaped and/or ring-shaped conductors connected to the poles of an energy source in such a way that energization entails deformation of packages in opposite directions, namely the deformed packages have confronting concave or convex sides. This increases the distance which is covered by the valving element in response to energization of the packages.
