Fuel injection valve for internal combustion engines
Abstract:
A control device (52) of a fuel injection valve has a mushroom-shaped intermediate valve member (56) which is guided with a sliding fit (58′) in a first intermediate plate (12). An injection valve member (28), which has a control piston (28′), for opening and closing injection openings in order to realize intermittent injection processes defines a control space (54) together with a guide sleeve (36) and the lower face (12a) of the first intermediate plate (12). A second intermediate plate (14) is situated between the first intermediate plate (12) and a housing body (10), and has a valve space (70) which is hydraulically connected to the end side of a shank (58) of the mushroom-shaped intermediate valve member (56).
