Abstract (en)
[origin: DE19947194A1] The fuel injection valve has a valve body (1), containing a piston valve element (4), displaced axially against a closure spring (21), within a valve bore (5), for controlling at least one fuel injection opening (8). The valve element is enclosed by a control space (10), coupled to a feed channel (2) via an annular gap and to a leakage oil space (20) via a control bore. The volume of the control space is reduced during the closure movement of the valve element for displacement of fuel into the leakage oil space.
