Fusible link, gas tank, and method for assembling a fusible link and for installing same in a gas tank

Abstract

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