Abstract
The invention relates to an electromagnetic valve for distributing cryogenic propellant for a space launch vehicle. The valve comprises two seats each oriented in a direction opposite to the other seat; a passage connecting the seats; and two shutters opening and closing the seats. The valve also comprises a magnetic circuit with a magnetic coil and a magnetic plunger that is driven by the magnetic flux of the coil and which in turn drives the shutters relative to their respective seats so as to open and close the seats. The plunger is placed between the shutters such that each shutter closes its seat by moving the plunger away from the corresponding seat. The movement for opening a seat is performed by moving the plunger towards the seat so that it does not crush the shutters against their seats.
