Abstract: The invention relates to a device for storing and supplying fluid, comprising a cryogenic tank, a withdrawal circuit comprising a first withdrawal line comprising a first heat exchanger located outside the tank, the withdrawal circuit comprising a set of one or more valves permitting withdrawal, in the process entering the first heat exchanger, an electronic control member for making at least some of the set of valves open/close, when the set of valves is configured to not allow withdrawal, the electronic control member being configured to switch the set of valves to a first state, in which at least a portion of the internal volume of the first heating heat exchanger is fluidically isolated from at least a portion of the rest of the withdrawal circuit, or a second state, in which at least a portion of the volume of the heating heat exchanger fluidically communicates with at least a portion of the rest of the withdrawal circuit.

Abstract: Fluid flow control valve comprising a tubular body extending in a longitudinal direction with a fluid inlet and a fluid outlet situated respectively at the two longitudinal ends of the body, the valve comprising a nozzle and a piston connected to the body, the piston being housed in the body, the nozzle being made up of a part provided with a fluid passage having a calibrated dimension, the passage emerging at one end of the nozzle and forming a seat, said seat being situated against a terminal end of the piston forming a shutter preventing the flow of fluid in the closed position of the valve, the piston comprising a body defining a passage for the fluid in the body for the flow of the fluid between the inlet and the outlet, the body of the valve consisting of a material having a different expansion coefficient from the piston or the nozzle, the valve comprising a heating member which, depending on the heating power delivered, makes it possible to separate the end of the nozzle and the piston by differential
