The invention relates to a fusible link (100) for installation in a through-opening (4) in a gas tank (1000), having a tension rod (1), a guide sleeve (2) with at least one fluid-guiding duct (2a) for guiding gas out of the gas tank (1000) into the environment of the gas tank (1000), and a fusible sheath (3), wherein the guide sleeve (2) is formed in a ring around the tension rod (1) at least in some sections, and the fusible sheath (3) surrounds the guide sleeve (2) in a sheath-like manner at least in some sections, wherein the tension rod (10) has a tapered section (1a) which tapers in a direction away from the gas tank (1000) when installed in the gas tank (1000), the guide sleeve (2) has at least one predetermined breaking section (2b) which, when the fusible link (100) is installed into the through-opening (4), breaks to introduce fusible material (3a) into the at least one fluid-guiding duct (2a), as a result of which fused material (3a) from the fusible sheath (3) can pass into at least some sections of the at least one fluid-guiding duct (2a) to block a gas flow through the at least one fluid-guiding duct (2a), and the tension rod (1) and the guide sleeve (2) have a higher strength and/or temperature resistance than the fused material (3a). The invention also relates to a method for assembling a fusible link (100) and for installing same in a gas tank (1000).

A pressurization device for pressurizing an enclosure may include a container containing a pressurized fluid, a pin that is inserted into the container, an actuator, and a heating device operably coupled to the actuator. The actuator may initially hold the pin in a closed position and allow the pin to move to an open position, disengaging from the container when the actuator increases in temperature. The pressurized fluid may force the pin toward the open position to release the pressurized fluid from the container. The actuator may include a frangible hollow bulb configured to fracture at a pre-defined temperature. The pressurized fluid may be vented into the enclosure through at least one fluid passage in fluid communication between the enclosure and the container.

Embodiments are directed to compressed gas storage units exhibiting one or more safety features. Particular embodiments employ a pressure relief mechanism to rapidly yet safely vent the contents of the tank in the event of a fire. The mechanism may comprise an internally piloted relief valve in communication with temperature-sensitive element(s) present along the tank dimensions. Under high temperature conditions indicative of a fire, the element communicates a signal to open the internally piloted relief valve. In some embodiments the element is configured to communicate a heat signal (e.g., by thermal conduction). In certain embodiments the element is configured to communicate a pressure change signal (e.g., pneumatic, hydraulic). In other embodiments the element may communicate different signal types, such as electric (e.g., thermoelectric) or mechanical (e.g., shear or tension forces). Also disclosed is a module incorporating a plurality of tanks to offer enhanced storage capacity.

The single-use valve to be installed on a line for transporting a fluid includes a tubular body, which is intended to be placed on the line and contains a mobile element that is able to take up two positions in the tubular body. Each position allows the fluid to pass through the tubular body or not, one being a standby position, while the other is an active position. Inside the tubular body, a driver able to move the mobile element such that the mobile element passes from its standby position to the active position. The driver includes a pretensioned elastic device. Outside the tubular body, a device for maintaining the pretension connects to a controller able to deactivate the device for maintaining the tension.
