ABSTRACT:
The invention pertains to a crashworthy valved fitting for interconnecting a tank, such as a fuel tank, with a fluid line wherein valve structure is manually operated, and fluid pressure assists in maintaining the valve in a closed condition. An extension defined upon a Tee fitting body, which may be separated therefrom at a frangible location, is circumscribed by a mounting surface and extends into a tank opening, and the extension side wall includes a plurality of orifices whereby communication between the tank and the fitting is achieved. A displaceable valve selectively seals the extension orifices, and a manually displaceable valve actuator incorporates locking means for maintaining the valve in the open position, and permitting releasing of the valve of for movement to a closed position. Pressure faces defined upon the valve of differential areas subjected to the pressurized medium produces a force for assisting to maintain the valve in the closed condition.
