Abstract (en)
[origin: WO2004051071A1] Disclosed is a fuel injection device (1) for internal combustion engines, comprising a control chamber (2) that is connected to a high-pressure end (5), and a control valve (6) which is connected to said control chamber (2) by means of a valve connection (8) located at a low-pressure end while being connected to a low-pressure end (7) by means of a first valve connection (9) located at a low-pressure end via a first discharge throttle (11). A second valve connection (10) of the control valve (6), which is located at a low-pressure end, is connected to the low-pressure end (7) via a second discharge throttle (12). The connection between the valve connection (8) located at a high-pressure end and the low-pressure end (7) is blocked in a first valve position while said valve connection (8) located at a high-pressure end is connected to both valve connections (9, 10) located at a low-pressure end in a second valve position and is connected to one of the two valve connections (9, 10) located at a low-pressure end in a third valve position.
