Abstract

Fuel injection valve has a cavity, which is provided with the housing in which a piezo-actuator (15) is arranged, which exhibits a piezo-element (17). The valve has a piezo-element, which is connected in such a way with the housing by welding or by adhesive bond (40) so that the fuel tank (24) is locked externally.
