Abstract
The system and method of the present invention provides an inflation device, such as a life preserver, that is automatically actuated by hydrostatic pressure. A diaphragm that is moveably responsive to fluid force created by fluid pressure actuates a first stage for providing a first force, that in response, actuates a second stage for providing a second force. The second force provided by the second stage is transferred by a force translation system to pistons, which in turn puncture CO cartridges. The punctured CO cartridges then release stored CO and inflate a previously deflated life preserver.
