Abstract (en)
[origin: WO0150008A2] The invention relates to a fuel injection device for internal combustion engines with a solenoid valve (24) which has a damping chamber (40) and a relief chamber (41). Said chambers are hydraulically connected by both a laminar and a turbulent damping throttle (39, 51). This reduces the ripple of the characteristic curves of the fuel injection system, thus improving its operation.
