Abstract
A fuel injection valve for internal combustion engines, having a valve body with longitudinal bore terminating in a valve seat. In the region of the valve seat, at least one injection opening connects the bore with the combustion chamber of the engine. A valve member disposed in the bore cooperates with the valve seat for controlling the at least one injection opening. Between the wall of the bore and the valve member, a pressure chamber is embodied that can be filled with fuel at high pressure. The valve body is surrounded, in the region of the pressure chamber, by a sleeve that has anisotropic strength properties, so that the valve body exhibits less deformation from the pressure in the pressure chamber.
