Abstract
A fuel injection valve includes a housing in which a pistonlike valve member is disposed longitudinally displaceably in a bore to cause at least one injection opening to communicate with a pressure chamber embodied in the housing. An inlet conduit discharges into the pressure chamber to fill the pressure chamber with fuel at high pressure. A fuel-filled control chamber in the housing at least indirectly exerts a force acting in the closing direction on the valve member. The control chamber communicates with the inlet conduit and can be made to communicate via a control valve with a leak fuel chamber. A damping chamber communicates with the inlet conduit via a throttle.
