Abstract
An inflation mechanism is provided for automatically inflating a life preserver or the like upon immersion in water. The mechanism includes a housing, a first piston slidably mounted within the housing, a second piston slidably mounted within the first piston, and a water-activated chemical positioned in a chamber between the two pistons. Upon immersion in water, the chemical reacts therewith creating a gaseous end product. The pistons are forced apart by the gas. One of them includes a piercing pin for puncturing the membrane of a CO.sub.2 cartridge. If the mechanism is not totally immersed in water, the piston including the piercing pin is restricted from moving through the membrane.
