The present invention relates to an inflator mounted on protective equipment, comprising: a main body (100) having a cylindrical structure that is open at the top and bottom thereof, wherein the main body (100) has a key-ball insertion hole (110) and a gas supply hole (120) that are formed on portions of a lateral side thereof, and a bomb (600) for storing compressed air is coupled to the lower side of the main body (100); an eccentric lever (200) that is rotatably coupled to the upper opening of the main body (100) through a rotation shaft (230) and includes a lever (210) that adjusts a downward pressure by rotating an eccentric drum part (220) having the shape of a circular plate; a perforation part (300) that provides a restoring force downward according to the pressure state of the eccentric lever (200) and perforates the bomb (600) to allow the gas in the bomb (600) to be supplied to a user's protective equipment through the gas supply hole (120); and a key-ball (400) that confines the movement of the perforation part (300) while being inserted into the key-ball insertion hole (110) and separates from the key-ball insertion hole (110) according to the state of the outside to operate the perforation part (300).

An inflator includes an inflating head and a piercing member. The inflating head has an inlet hole, an insertion hole communicating with the inlet hole, a -24UNF inner thread formed on an inner circumference of the inlet hole, an annular airtight member disposed in the inlet hole and adjacent to the insertion hole, and an outlet hole communicating with the insertion hole. The piercing member is movable between a first position and a second position within the insertion hole and has a conically shaped spiking portion. When the piercing member is in the first position, the spiking portion is distant from the inlet hole. When the piercing member is in the second position, the spiking portion passes through the airtight member and enters the inlet hole.

A retention unit for securing a charged gas cylinder to a body of an aircraft includes a container having an opening and configured to cover the charged gas cylinder. The retention unit also includes a plurality of flaps coupled to the container and configured to be attached to the body of the aircraft using a contact adhesive. The retention unit also includes a drawstring disposed around the opening of the container and configured to provide a closure of the container around a neck of the charged gas cylinder inside the container.

An initiator for opening a pressurized gas cylinder is disclosed herein. The initiator includes a housing having a first end and a second end, a lance disposed within the housing, the lance configured to slide from the first end of the housing to the second end of the housing and out through the second end of the housing, a spring disposed within the housing between the first end of the housing and the lance, and a wire coupled to the first end of the housing and to the lance, the wire configured to hold the spring in a compressed state, the wire further configured to break in response to an electric current.

Provided is a nozzle assembly including a valve assembly configured to be coupled to a tank, the valve assembly including a valve body having a first end, a second end, and a first passage extending therebetween, and a valve disposed in the first passage, and a regulator assembly configured to be coupled to the valve assembly, the regulator assembly including a regulator body having a first end, a second end, and a second passage extending therebetween, a nozzle coupled to the regulator body and having an outlet in communication with the second passage, a spindle having a first end disposed in the second passage and a second end surrounded by the nozzle, and a piston assembly disposed in the second passage.

This invention discloses an inflator mechanism for rafts and life vests that performs a multitude of functions required for rescue and underwater deployment of personnel and devices. The inner cylinder in this disclosure is actuated by a plethoria of inputs, manual, automatic selectable pressure sensing, or dualled hydrostatic sensors which can each be safely selected by function selection. Since the inflator uses spring discs to drive a penetrator which mechanically punctures a membrane of an inflation gas source and actuated by an electronically controlled solenoid, dissolvable elements, conductivity switches and preset check valve actuators are eliminated increasing the safety and reliability of the actuator. Electronic control further permits user enabling of inflation depth actuation and the multiple water sensors prevent failure of actuation due to splashes and humidity effects on sensors. The actuator mechanism is self cocking, indicates proper installation of gas source enables use of several gas source cylinders and is multiply reusable.

A device for controlling the release of gas from a pressurised container, the device comprising a plug comprising a passage therethrough, a diaphragm within said passage, wherein said diaphragm is configured to initially prevent flow of gas through said passage, and is rupturable or displaceable to allow gas to flow through said passage once said diaphragm is ruptured or displaced. The device further comprises a screw located within said plug and comprising a lance configured to move towards said diaphragm upon rotation of said screw, wherein said lance is configured to rupture or displace said diaphragm so as to allow flow of gas through said passage and out of said plug, once said screw is rotated a predetermined amount.

Provided is a nozzle assembly including a valve assembly configured to be coupled to a tank, the valve assembly including a valve body having a first end, a second end, and a first passage extending therebetween, and a valve disposed in the first passage, and a regulator assembly configured to be coupled to the valve assembly, the regulator assembly including a regulator body having a first end, a second end, and a second passage extending therebetween, and a piston assembly disposed in the second passage, the piston assembly including a piston movable between a first position to contact and open the valve, and a second position away from the valve such that the valve closes, the piston being independently movable relative to the valve.

A cap configured to be fastened to a gas canister. The cap includes a main body provided with at least one hole. The cap includes an appendix which protrudes from the main body. The appendix is provided with a deviation surface which is arranged facing the at least one hole so as to deflect a fluid exiting the at least one hole. Also provided is an assembly including a gas canister provided with the cap. Further provided is a personal protective device with an inflatable bag connected to said assembly.
