摘要：
A fuel injection device for internal combustion engines, having a control valve located between high-pressure and low-pressure sides and which opens or blocks the communication of a control chamber with the low-pressure side, and an outlet throttle located between the control valve and the low-pressure side, the control valve having a first valve position, in which the communication of the control chamber with the low-pressure side is blocked, a second valve position, in which the control chamber communicates with the low-pressure side via a first outlet conduit, and a third valve position, in which the control chamber communicates with the low-pressure side via a second outlet conduit having an outlet throttle.
