ABSTRACT:
A light, portable, miniaturized tire inflator adapted to fit in a limited space, such as in a tire well for a deflated, space-saving tire in a trunk of an aubomobile, and adapted to be carried or held in one hand. The tire inflator includes: a pyrotechnic material, an ignitor mechanism, a pressure vessel, and a nozzle. The pyrotechnic material generates an inflating gas upon burning to inflate a tire without a source of stored fluid. The ignitor mechanism is located adjacent to the pyrotechnic material to ignite and cause the pyrotechnic material to burn. The pressure vessel holds the pyrotechnic material. The pressure vessel has a tire end and a pyrotechnic end. The nozzle is mounted on the tire end of the pressure vessel. The nozzle is adapted to be connected directly to a valve of the tire. In one embodiment, connection of the nozzle to the tire valve activates the ignitor mechanism.
