Definitions

• the present invention relates to cryogenic solenoid valves that can be used to control a flow of cryogenic fluid, especially cryogenic fuel contained in a motor vehicle tank operating said fuel, in particular for its propulsion.
• valves for automotive liquid hydrogen storage tanks used in a fuel cell and / or directly as fuel in an internal combustion engine.
• the liquid hydrogen tanks contain between 5 and 13 kg of liquid hydrogen, at a temperature of 20 K, and at pressures typically between 1 and 13 bar.
• an automotive liquid hydrogen tank has a fill line, a gas drain line and a liquid drain line.
• the valves controlling the gas flows containing hydrogen in each line are conventionally installed in a vacuum chamber called a "valve box" in order to thermally isolate the cold fluid circuits at 20 K from the ambient temperature.
• the object of the present invention is to propose a cryogenic solenoid valve architecture that avoids the above-mentioned problems, and that is particularly suitable for consumer-car applications with increased reliability and minimum space requirements.
• the solenoid valve comprises a seat body insertable in a fluid circuit and forming a valve seat, a valve assembly comprising a valve member cooperating with the seat and connected by a rod to a electromagnetic actuator, the actuator being mounted on a first end of a tubular shaft enclosing the valve assembly and whose second end is fixed to the seat body.
• valve member has a tubular shape enclosing one end of the stem and is slidably mounted in a bore of the seat body
• the second end of the shaft is mounted on a tubular portion projecting from the seat body partially defining the bore
• the first end of the barrel is connected to a tubular valve head partially enclosing a plunger of the actuator cooperating with the rod and comprising a mounting flange in a wall of a vacuum enclosure enclosing the barrel and the seat body .
• the present invention also relates to the use of such a cryogenic solenoid valve for controlling the flow of cryogenic fuel (oil) contained in a tank, in particular a tank of a motor vehicle.
• the present invention finally relates to an automobile fuel tank equipped with a vacuum valve box and at least one solenoid valve as defined above.
• FIG. 1 is a view in longitudinal section of a solenoid valve according to the invention
• FIG. 2 is a schematic top view of a pair of solenoid valves according to Figure 1 on a vacuum valve box;
• Figure 3 is a similar view of Figure 1 showing the possibility of using the solenoid valve according to the invention for non-cryogenic fluids.
• the solenoid valve essentially comprises a seat body 1 insertable into a fluid circuit 2, typically a cryogenic fluid supply circuit of a motor member of a motor vehicle, and forming a seat 3, a valve head 4 supporting an electromagnetic actuator 5 and a valve assembly comprising a valve head 6 connected by a rod 7 made of a material that is weakly heat-conductive and non-magnetic, for example in highly alloyed stainless steel, to the magnetic core 60 of the actuator 5.
• valve head 4 comprises a lower tubular piece 40 comprising a radially outwardly extending flange 8 and a tubular end portion 9.
• the seat body 1 comprises, coaxially with the seat 3, a bore 10 formed in part in a tubular portion 11 extending outwardly.
• a long tube 12 sealingly fitted on the tubular portions 9 and 11 coaxially enclosing the rod 7, connects the valve head 4 to the seat body 1.
• the tube 12 typically has a length between 3 and 5 times its diameter.
• the valve head 6 comprises a tubular part 13 mounted to slide tightly in the bore 10 and a frustoconical end piece 14 forming a valve proper, cooperating with the seat 3 and connected to the lower end of the rod 7.
• the upper end of the rod 7 is connected to the core 60, which is biased, in the closing direction of the valve 6 against the seat 3, by a spring 15 bearing on the polar mass 16 of the actuator 5.
• the flange 8 of the part 40 of the solenoid valve head 4 is used for sealing the solenoid valve in the wall 17 of a vacuum valve box 18, also visible in Figure 2, associated with a cryogenic fluid reservoir 19, including a liquid hydrogen tank of a motor vehicle.
• the coil of the actuator 5 is located outside the valve box 18, so easily accessible and at room temperature without interacting on the quality of the inter-wall void during its activation.
• the seat 3 in the seat body 1 is always located in the valve box 18 under vacuum being permanently removed from the ambient atmosphere.
• the coil of the actuator 5, using epoxy resin Ea is made free of thermal shock due to the passage of cryogenic fluid to Very low temperature in the seat body 1.
• the mounting 40 of the valve head 4 on the valve box 18 is designed to remain tight also at the cryogenic temperatures of the fluid flowing in the circuit 2 (in case of accident with reversal of the vehicle, for example).
• the solenoid valve architecture according to the invention is also suitable for use in non-cryogenic environments, in the absence of any vacuum valve box.
• the tube 12 of stainless steel is removed and replaced for example by an extension of the annular end portion 9 of the valve head 4 to be mounted directly on the tubular portion 11 of the seat body 1, the rod 7 here having an extremely small extension and can be made of any suitable materials.
