Inflator

摘要

An inflator for inflating an inflatable device to which it is connected via fill tubes or in which it is positioned. The inflator comprises a power module assembly and an adaptor assembly intended to be threaded into or onto the threaded neck of a gas cylinder (not shown). The power module assembly employs one or more power primers that are fired when a tether is pulled to remove the actuator cup to release a spring-loaded actuator pin to fire the power primer(s). The escaping gases from the power primer(s) then drive a pierce pin to fracture a frangible seal allowing gas in the gas cylinder to then flow into the inflatable device and inflate the same.

1. An inflator for inflating an inflatable device with gas from a gas cartridge,
comprising in combination: a power module assembly having an actuator pin reciprocatably mounted therein and an actuator spring for spring-loading said actuator pin that is held in a cocked, ready position until actuated; a ballistic module containing at least one power primer that is fired by said actuator pin when actuated, said power primer producing gas to drive a pierce pin into engagement with a frangible seal to release the gas from the gas cartridge through an adaptor assembly into the inflatable device; and a syphon tube pivotably and fluidly connected to an output of said adaptor assembly allowing the tube, when the gas cylinder is oriented horizontally, to pivot downwardly toward the inside of the gas cylinder to draw liquid gas therefrom.
