Fuel injection valve for internal combustion engines

In a fuel injection valve for internal combustion engines, having a bore (5) embodied in the valve body (1), in which bore a pistonlike valve member (4) is disposed that is axially movable counter to the closing force of a spring (21) and that on its end toward the combustion chamber controls at least one injection opening (8) and that has a portion (4b) toward the combustion chamber, which portion is disposed in an annular conduit (3, 18) filled with fuel at high pressure, and on which portion (4b) of the valve member (4) a pressure face (9) is embodied, and the pressure of the fuel acts on the pressure face (9) counter to the closing force of the spring (21), wherein the valve member (4) has a second pressure face (12, 122), by which a control chamber (10) surrounding the valve member (4) can be defined, so that upon the closing motion of the valve member (4) the volume of the control chamber (10) can be decreased, and the control chamber (10) is in constant communication, via a throttle gap (16), with the annular conduit (3, 18) and a further communication with an oil leakage chamber (20), which beyond a certain stroke of the closing motion of the valve member (4) is throttled via an annular gap (15, 115) which is formed between a control bore (40), disposed between the control chamber (10) and the oil leakage chamber (20), and a control piston (11, 111) of the valve member (4), the control piston plunging into the control bore (40) upon closure.
