ABSTRACT:
An inflator for automatically inflating an inflatable article, such as a personal flotation vest, upon immersion in water. A plunger is movably mounted within a housing and is movable with respect to a pressurized gas canister attached to the housing. An internally resettable automatic actuator mechanism, mounted within the housing, acts on the plunger to move the plunger to pierce the canister to release the pressurized gas therefrom through the housing to the inflatable article attached to the housing. A pair of spaced water sensor probes mounted in the housing provide a signal to a control device indicating that the housing is immersed in water. The control device activates the automatic actuator mechanism to release a spring-biased ram from a latched position such that the ram engages and urges the plunger under force into the sealed end of the gas canister. The automatic actuator mechanism, in a preferred embodiment, includes a motor actuated by the control device and gears which couple the motor output shaft to a slider which latches the ram in a retracted position. A manual lanyard is extensibly mounted within the housing and includes a cam which acts on the plunger to manually urge the plunger into the gas canister when the lanyard is extended outward from the housing.
