<p>The invention pertains to a conduit assembly consisting of a flexible hose having a self sealing valved fitting at each end, such assembly being suitable for interconnecting aircraft fuel cells. The assembly is crashworthy in that upon displacement of the fittings relative to each other the resultant tension force produced in the hose causes the valves within the fittings to automatically close prior to the rupture of the hose thereby minimizing the likelihood of fuel spillage and fire. Frangible elements within the fittings fracturable upon predetermined hose tension forces existing insure the desired sequence of valve operation without requiring complicated apparatus, cables or links which would interfere with the flexibility of installation.</p> |
