ABSTRACT:
A fuel injection device for internal combustion engines having a magnet valve that has a damping chamber and a relief chamber which communicate hydraulically through a damping throttle that damps in both laminar and turbulent fashion. As a result, the waviness of the characteristic curves of the fuel injection system is reduced and its function is improved.
