ABSTRACT:
An auto inflator having a dissolvable element that abuts and prevents sliding movement of a retainer pin that is under very low pressure. The auto inflator further includes a rotatably mounted lever arm that effects puncturing of a gas-filled cartridge by a puncture pin when the lever arm is rotated. Rotation of the lever arm occurs when the retainer pin is retracted upon dissolution of the dissolvable element. A slide member is slidably mounted in an elongate track and is biased to slide away from the retainer pin but the retainer pin, when extended, prevents that movement. The retainer pin is biased to retract, but the dissolvable element prevents that retraction until it is dissolved. Upon dissolution, the retainer pin retracts and the slide member moves along the track, pulling a lanyard with it. The lanyard is engaged to the lever arm and effects its rotation so that the puncture pin is driven into the membrane that seals the cartridge. An inspection opening in the housing is positioned so that the lever arm is visible through the opening if the head of the lever arm is bearing against the head of the puncture pin and is not visible if the lever arm is in its position of repose. Visibility of the lever arm through the opening indicates that lever arm rotation has occurred and that the cartridge is spent. Imperforate baffle walls protect the dissolvable element from small quantities of water.
