Abstract

An auto inflator having a dissolvable element 66 that abuts and prevents sliding movement of a retainer pin 60 that is under very low pressure further including a rotatably mounted lever arm 30 that effects puncturing of a gas-filled cartridge by a pin 24 when rotated. Rotation of the lever arm occurs when the retainer pin is retracted upon dissolution of the dissolvable element 66. A slide member 44 is slidably mounted in a track and is biased to slide away from the retainer pin 60 but the pin 60, when extended, prevents that movement. The pin 60 is biased to retract, but the dissolvable element prevents that retraction until it is dissolved when the retainer pin retracts and the slide member 44 moves along the track, pulling a lanyard 49 with it. The lanyard 49 is engaged to the lever arm 30 and effects its rotation so that the pin 24 is driven into the membrane that seals the cartridge.
