<p>In a fuel injection valve for internal combustion engines, having a valve housing, having an axially movable valve member for opening and closing an injection opening of the injection valve, and having a part, which acts in the closing direction of the valve member, which is guided with its end remote from the injection opening in a bore of a first valve piece inserted into the valve housing and with this end, encloses a control pressure chamber in the first valve piece, which control pressure chamber can be connected to a high-pressure fuel connection via an inlet conduit, which is provided with at least one inlet throttle, and can be connected to a low-pressure fuel connection via an outlet conduit, which has an outlet throttle and can be closed by a movable control valve member, where the injection process can be controlled by means of the fuel pressure in the control pressure chamber, the proposal is made that at least the section of the inlet conduit provided with the inlet throttle be disposed in a second valve piece inserted into the valve housing, which second valve piece is connected to an opening embodied in the first valve piece in such a way that the section of the inlet conduit of the second valve piece provided with the inlet throttle feeds into the control pressure chamber of the first valve piece.</p> |
