Abstract (en)
[origin: WO9803789A1] A solenoid valve (1) having a fuel inlet (3) and a fuel outlet (4) and containing a solenoid coil (5) combined with power supply control means therefor, as well as a magnetic piece (6) and a plunger (7) with facing contact surfaces. The plunger (7) is connected to sealing means (8) for opening and closing said outlet (4) by moving the plunger (7) relative to the magnetic piece and causing mutual engagement between the contact surfaces thereof. Said solenoid coil power supply control means (5a) are arranged to apply a current (I) to said coil that has a surge phase (A) and a plateau phase (M). At the end of the surge phase, the current has a shallower slope (A2) than at the start (A1) thereof, whereby the impact of the plunger (7) against the magnetic piece (6) is reduced as the valve body outlet is opened.
