A fuel injection system with a fuel injection valve and a control valve, which control valve has a control valve member that can move longitudinally in a control valve bore. The control valve member is provided with a control valve sealing surface, which cooperates with a control valve seat and thereby controls the connection between a first pressure chamber and a second pressure chamber, where the first pressure chamber is connected to a high-pressure accumulation chamber. A bore is embodied in a valve body and contains a piston-shaped valve needle whose end oriented toward the combustion chamber controls the opening of at least one injection opening by virtue of the fact that it executes a longitudinal movement due to the impingement of the pressure in a pressure chamber; the pressure chamber is connected to the second pressure chamber by means of a supply conduit. The first pressure chamber is connected by means of a throttle to a damping chamber that is otherwise closed, as a result of which, pressure oscillations that are produced by the closing of the control valve are rapidly damped.
