Abstract
Solenoid valve including a seat body connected via an elongate tube to a valve head supporting the electromagnetic actuator, wherein said valve head is sealingly mounted in a wall of an evacuated valve box insulating the tube and the seat body from the outside. The invention is useful in particular in controlling a flow of cryogenic fuel, specifically liquid hydrogen, in a motor vehicle.

1-12. (canceled)
A cryogenic solenoid valve comprising:
- a seat body that can be inserted into a fluid circuit and that forms a seat
- a gate kit comprising a gate element interacting with the seat and connected via a stem to an electromagnetic actuator,
- the actuator being mounted on a first end of a tubular barrel partly enclosing the gate kit and whose second end is attached to the seat body, characterized in that the first end of the barrel is connected to a tubular valve head partly enclosing a plunger of the actuator interacting with the stem and comprising a collar for mounting in a wall of an enclosure under vacuum enclosing the barrel and the seat body.
