Abstract: A fail safe container and container insert are disclosed. A flexible container insert may convert energy from a catastrophic event, including but not limited to collisions, accidents, impacts, pressure container failures or explosions such as detonations, or other catastrophic incidents, into a stretching of an internal structure of a fail-safe container insert to minimize or prevent failure of the container insert and/or the container. The stretchability of the container insert may accommodate both temperature and shape changes to protect a container, including but not limited to a pressure vessel, from rupture or other failure. Accordingly, a container insert may be considered self-healing in that it may absorb the effects of catastrophic events to prevent failure, may return to a generally previous condition, and/or may seal or otherwise reduce or minimize breaches when they do occur.

Abstract: Provided is a fluid control valve assembly including: a main valve body having a first flow passage that is mounted on an inlet of a high-pressure vessel and through which a charging source gas passes, a second flow passage through which a feeding source gas passes, and a third flow passage to which the first flow passage and the second flow passage are connected; a manual valve that is mounted on the main valve body and that opens and closes the third flow passage; a solenoid valve that is mounted on the main valve body and that opens and closes the second flow passage by an electrical signal; a first check valve that is provided on the first flow passage to thus block a reverse flow of the charging source gas; and a second check valve that is provided on the second flow passage to thus block a reverse flow of the feeding source gas, and block the charging source gas from flowing in the second flow passage, to thereby prevent the charging source gas from flowing in the solenoid valve. Accordingly, a charging gas pressure of a high-pressure is prevented from being applied to a solenoid valve, to thereby prevent damage to the solenoid valve and to prevent a malfunction of the solenoid valve.

Abstract: A method of transferring a liquefied gas under pressure contained in a container into a tank or a gas transport network. The container is connected to a recirculation circuit that includes a heater and a recirculation pump connected in series with the heater, upstream from the heater, and arranged to discharge liquefied gas taken from the bottom of the container into the heater, the method including connecting the container to the tank or to the network, via a circuit for transferring the liquefied gas in the liquid phase and not having a pump; allowing the liquefied gas to be transferred to the tank or to the network via the transfer circuit under the effect of a higher pressure in the container; and operating the pump to compensate for the reduction in pressure inside the container during transfer.

Abstract: A flow direction restriction valve mechanism unit includes a pressure decreasing valve assembly that is located to be freely advance or retract in a combination valve cassette attached to an in-outlet secondary side flow path formed on the side of an outlet with respect to an intermediate transmission member in a flow path, and retracts by a pressure of gas; a first coil spring urging the pressure decreasing valve assembly in a retracting direction; a check valve that is located to be freely advance or retract with respect to the pressure decreasing valve assembly, and retracts by a pressure of the gas; and a second coil spring urging the check valve in an advancing direction. A gas induction passage H is formed in which the gas flows and acts on the pressure decreasing valve assembly such that the pressure decreasing valve assembly moves in the advancing direction.

Abstract: An operating method is provided for a cryo-compressed tank for supplying cryogenic hydrogen to a consumer of a motor vehicle under supercritical pressure at 13 bar or more. In order to compensate for pressure loss resulting from hydrogen removal, the removed hydrogen that has been heated in a heat exchanger is conveyed to a heat exchanger, provided in the cryo-compressed tank, by way of a tank pressure regulating valve and a branch line, which branches off of a supply line leading to the consumer. After flowing through the heat exchanger, it is introduced into the supply line downstream of the branching off of the branch line. Over a period of time that significantly exceeds the cycle times of a conventional frequency valve, either the removed amount of hydrogen is guided without limitation into the heat exchanger, provided in the cryo-compressed tank, the tank pressure regulating valve being completely open, or no return of the heated hydrogen into the heat exchanger occurs at all. Downstream of the branching off of the branch line, the supply line has a pressure regulating unit, which ensures that irrespective of the changes in the pressure in the supply line caused upstream of the pressure regulating unit by switching the tank pressure regulating valve, a sufficient and continuous supply of hydrogen to the consumer at the pressure required is guaranteed.

Abstract: A valve for a pressurized fluid cylinder. The valve comprises a shut off valve biased against a seat to seal the cylinder. An actuation element is movable linearly to open the valve against the biasing force. A linkage element couples the actuation element to the shut off valve and comprises a first piston towards its top and a second piston towards its bottom. The valve also comprises a gas refill inlet between the pistons such that refill gas pressure biases the linkage element away from the valve. The actuation element is a depressed position pushes against the linkage element to hold the linkage element down and the valve open so that the cylinder can be refilled. When the actuation element is in a non-depressed position, the linkage element is free to move with the refill gas pressure so that it is spaced from the valve.
