ABSTRACT:
A fuel injection valve for internal combustion engines has a valve body in which a pistonlike valve member is longitudinally displaceably disposed in a bore. The valve member is surrounded, over at least part of its length, by a pressure chamber that can be filled with fuel. On its end toward the combustion chamber, a valve seat is embodied in the bore, on which seat the valve member comes to rest with a valve sealing face in a closing position, so that the pressure chamber is disconnected from at least one injection opening located downstream of the valve sealing face. First and second parallel annular grooves are formed in the end region of the valve member disposed axially toward the valve seat and the valve sealing face is disposed between these two annular grooves.
