Abstract:
A fuel injection valve (10) comprises an intermediate valve with a mushroom-shaped intermediate valve member (78). The shaft (76) of the intermediate valve member (78) is guided with a sliding fit in the guiding passage (74) of an intermediate component (66). An annular space (120) is defined between the shaft (76) and the head (80) of the intermediate valve member (78) and the intermediate component (66), and a high-pressure inlet (86) opens into the annular space, which is formed by an inner annular space (108) and by a split ring space (118). The split ring space (118) is defined between the head (80) and the intermediate component (66), and is also radially outwardly defined by a sealing bead (112). The adhesion force between the intermediate valve member (78) and the intermediate component (66), which acts against the opening motion of the injection valve member (56), is minimized.
