Patent attributes
The flame arrester is optimized for installation within fuel containers, such as fuel tanks and portable fuel containers, or immediately within the neck of the tank or spout of the container. The flame arrester has an elongate, generally cylindrical skeletal frame having opposing first and second ends. The first end is configured as a mounting flange adapted for permanent, immovable installation within the tank or container. The frame is covered by a woven or nonwoven textile material, or alternatively, by a porous or foraminous sheet material. Fuel and vapors pass through the cylindrical textile wall, the porosity of the textile serving to prevent flame propagation through the textile material. The frame is formed of a flexible, fuel-impervious plastic material to allow the flame arrester to be bent or curved for installation within a curved tube.
