Abstract
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.
Claims8
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.
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
- said adaptor assembly comprising two threaded ports allowing connection of conventional fill tubes fluidly connected to the inflatable device to be inflated, said ports being oriented in different directions to minimize undesirable torque being imparted to the inflator during inflation.
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;
- said adaptor assembly comprising a diaphragm holder threadably positioned within a central bore and wherein said frangible seal comprises a diaphragm that seals the gas cartridge until being fractured by said pierce pin, said diaphragm being mounted to said diaphragm holder;
- and
- said diaphragm being mounted to said diaphragm holder by an annular rim that is crimped over the annular peripheral edge of the diaphragm and wherein said diaphragm comprises a threaded connection with a bore of said adaptor assembly to seal against a diaphragm seat formed in said bore of the adaptor assembly.
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;
- said adaptor assembly comprising a diaphragm holder threadably positioned within a central bore and wherein said frangible seal comprises a diaphragm that seals the gas cartridge until being fractured by said pierce pin, said diaphragm being mounted to said diaphragm holder;
- and
- said ballistic module comprising a firing assembly threadably positioned within a bore of said adaptor assembly;
- and
- said firing assembly further comprising a power primer assembly positioned within a central bore, said power primer assembly comprising a bushing having at least one primer cavity for receiving said power primer and a bleed hole extending from said primer cavity to said central bore.
