A valve assembly includes a valve housing defining therein a fluid flow channel between a first end arranged to be connected to a source of pressurised fluid, and an outlet a frangible member disposed within and across the fluid flow channel, rupture means for rupturing the frangible member and biasing means for biasing the means for rupturing into contact with the frangible member to cause rupture thereof. The assembly also includes retaining means for retaining the rupture means out of contact with the frangible member to prevent rupture thereof and release means configured to release the retaining means to allow the biasing means to bias the rupture means into contact with the frangible member. The retaining means includes a bearing extending to engage the biasing means and hold it in a compressed state and the assembly includes also includes securing means for securing the bearing in the engaged state.

A device for the inflation of an inflatable life vest, notable in that it includes a storage casing containing at least two cartridges of pressurized gas which are arranged side-by-side and touching one another to form a row, and a release casing comprising at least one striker device that makes it possible, in the event of activation, to puncture each of the said cartridges simultaneously or in succession to release the gas they contain in gaseous form to the outside of the inflation device through at least one orifice made on the release casing, the said storage and release casings being in the overall shape of a flattened hollow parallelepiped and joined together removably and in a manner that is gastight with respect to the gas contained in the said cartridges.

An inflatable bag includes a gas cylinder filled with a compressed gas and having a bottle mouth for discharging the compressed gas, a hole-piercing device pressable to pierce into the bottle mouth for letting the compressed gas be discharged out of the gas cylinder, an inner bag surrounding the gas cylinder and the hole-piercing device and having air holes for the passing of the discharged gas, and an inflatable outer bag surrounding the inner bag and inflatable by the gas that is discharged out of the gas cylinder and flows through the air holes of the inner bag. By the above configuration, the inflatable bag is placed in a box around the object to be protected and quickly inflated to form a filling buffer without generating heat, ensuring that the protected object is not easily deteriorated and facilitating recycling and cleaning.

A valve includes a valve body having an inlet for fluid communication with a space or source containing pressurised gas, and at least one outlet. A membrane is arranged between the inlet and the at least one outlet. A membrane puncturing element is arranged for movement between a retracted, inoperative position and an extended position in which it punctures the membrane. An actuating piston is operatively coupled to the membrane puncturing element for moving the membrane puncturing element between its retracted and its extended positions, the actuating piston being received in a piston bore of the valve body. The valve body also includes a cartridge receiving chamber for receiving a sealed actuating gas cartridge. A cartridge puncturing device is provided for puncturing the actuating gas cartridge. An actuating gas flow passage communicates actuating gas released from the actuating gas cartridge to the actuating piston bore upon puncturing the actuating gas.

Provided is a pressure reducing tilt nozzle that includes a body defining a cavity having an inlet and an outlet, and a piston disposed in the cavity. The piston is biased in a first piston position away from the inlet allowing flow through the inlet and is movable toward the inlet to a second piston position preventing flow through the inlet when pressure in the cavity overcomes a biasing force biasing the piston in the first piston position.

Disclosed is a pneumatic inflation valve assembly, having: a valve housing defining a valve cavity and including an axial proximate end and an axial distal end, the proximate end including an outlet from the valve cavity and the distal end including an inlet into the valve cavity, the proximate end includes a motion hole, the distal end includes a receiving volume; and a poppet is disposed in the valve cavity that includes an axial proximate stem extending through the motion hole, an axial distal stem is disposed in the receiving volume and is moveable within the valve cavity between an opened position and a closed position, when the poppet is at the opened position the distal stem extends further into the receiving volume than at the closed position, and the center body is axially spaced from the proximate end and the distal end of the valve housing.

Liquefied gas tank that is easy to machine and quick to operate and bag for sealing cable ducts incorporating said tank. The tank is provided with breaking means for inflating sealed compartments composed of a main pipe (1) closed on one side, an outlet pipe (4) inserted on the other side of the main tube through a first end (6) and closed on the distal end thereof, wherein the outlet pipe is provided with a narrowing (5) that defines a breaking point and an internal orifice (8) that extends from the first end of the outlet pipe to the narrowing (5) towards the distal end, and wherein the size of the narrowing (5), the size of the orifice (8) and the length of the outlet pipe (4) are determined such that a force applied on a lever of between 19N and 80N will break the outlet pipe (4) at the breaking point (5), releasing the gas through the orifice (8).

A retention assembly for a valve assembly of a charged cylinder may comprise a first fitting coupled to the valve assembly and a second fitting coupled to the charged cylinder. A retaining member may be coupled between the first fitting and the second fitting. The retaining member may be disposed within an interior chamber of the charged cylinder.

A high pressure cartridge inflator has a body including an air inlet port connectible to a high pressure cartridge, an air outlet port connectible to a valve of an object to be inflated, an air discharge port, and defining a first channel extending from the air let port to the air outlet port and a second channel extending from the first channel to the air discharge port. A pressure indicator is disposed within the body and is fluidly connected to the first and second channels. A safety device is disposed in the second channel and is configured to selectively prevent and allow high pressure air in the high pressure cartridge to flow out of the body through the air discharge port.

Provided is a pressure reducing tilt nozzle that includes a body defining a cavity having an inlet and an outlet, and a piston disposed in the cavity. The piston is biased in a first piston position away from the inlet allowing flow through the inlet and is movable toward the inlet to a second piston position preventing flow through the inlet when pressure in the cavity overcomes a biasing force biasing the piston in the first piston position.
