Autoclave cryogenic electromagnetic valve for a space launch vehicle

An electromagnetic valve, said valve comprising:

• two seats each oriented opposite the other seat;
• two shutters that each cooperate with one of the seats so as to be able to block and open the respective seat;
• a passage connecting the seats;
• and
• a magnetic circuit with a magnetic plunger able to be driven by a magnetic field source, the plunger moving the shutters relative to their respective seats,
• wherein the plunger is placed between the shutters such that each shutter closes its respective seat by moving the plunger away from the seat, and
• wherein the valve comprises three openings, the fluid being able to flow from a first opening to one of the second and third openings, the second and third openings being each in fluidic connection with a respective seat of the two seats, such that when a shutter blocks one of the two seats, the fluid can flow from the first opening to the opening in fluidic connection with the other of the two seats, and vice versa, and
• wherein the plunger comprises a through-duct configured to connect the seats of the passage,
• and the valve further comprises at least one plunger guide, wherein at least one of the seats is formed on said plunger guide.
