CONTROLLED LEAKAGE CONDUIT FOR DELIVERING A FLUID TO A HEAT SOURCE

摘要

A fluid conduit adapted to form ruptured orifices in areas along its length when the areas or portions are subjected to selected temperatures resulting from the proximity of a high temperature heat source, the orifices thereby selectively delivering the fluid to reduce such temperature of the heat source. The conduit includes a pressure-rupturable body and reenforcing elements for reenforcing portions of the body to withstand high temperatures and to assure that the conduit continues to transmit fluid past ruptured conduit areas. The body is adapted to rupture in portions not supported at high temperatures by the reenforcing elements where combined internal pressure and the reduced strength at high temperatures results in failure of these portions of the body. The portions of the body which do not rupture continue to function as a conduit leading fluid to other areas along the conduit.
