ABSTRACT:
An inflator for automatically inflating an inflatable article, such as a personal flotation vest, upon immersion in water. A plunger is mounted in a housing and is movable with respect to a pressurized gas canister attached to the housing. An actuator mechanism, mounted within the housing, acts on the plunger to move the plunger to pierce the canistor to release the pressurized gas through the housing to the inflatable article attached to the housing. A pair of spaced water sensor probes provide a signal to a control device mounted within the housing when immersed in water. The control device automatically activates the actuator to drive the piercing end of the plunger into the canister. A manual lanyard is extensibly mounted within the housing and is connected to a link and lever to drive the plunger into the canister when the lanyard is pulled outward from the housing.
