ABSTRACT:
The invention is 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 automobile, and adapted to be carried or held in one hand. The tire inflator includes a metal, preferably steel pressure cannister comprising in one embodiment a pressure vessel and a pressure head cap assembly, a pyrotechnic material in the pressure vessel, an ignitor mechanism and a nozzle in the head cap assembly, an internal insulation liner for said pressure cannister to reduce the temperature level of the cannister to a level acceptable to an external insulation, such as plastic foam or paper, of about 350.degree. F, and a resilient insert for example rubber, in the nozzle end to mate and thread in one embodiment, with the metal tire valve threads, and prevent cross threading, while providing a seal with the tire valve for inflation of the tire. The rubber insert also allows the tire inflator simply to be pushed on the valve and form the required seal, rather than threaded thereto, due to the resilient nature of the rubber.
