Abstract

An inflator (10) comprising: a pressure tank (12, 14, 16, 20) for storing a quantity of stored inflation gas under pressure. The pressure tank comprising a first burst disk (46) in communication with the stored inflation gas; a sliding piston (72) including at one end thereof a sharp edge (74) for puncturing the first rupture disk and at its other end a second rupture disk (80). The sliding piston (72) movable into engagement with the first rupture disk in response to the build up of pressure acting on the second rupture disk (80) in response to the burning of propellant material (90) thereby permitting egress of the stored inflation gas. The second burst disk being ruptured by the continued build up of pressure due to the burning propellant whereupon after the rupturing of same the heated products of combustion resulting from the burning propellant flow through the sliding piston (72) to increase the temperature of the stored inflation gas prior to its exit from the inflator.
