A tank mounting structure includes a frame, a band, and a tank protector. The frame is configured to fix the tank. The band is configured to fix the tank in a state where the band sandwiches the tank with the frame and the band deforms in accordance with expansion or contraction of the tank. The tank protector is configured to be fixed to an inner side of the band or an outer side of the band.

A pressure vessel includes an outer shell and pressurized elements disposed within the outer shell that contains a pressurized gas. The pressure vessel includes a bearing system disposed between the pressurized elements and the outer shell, and the bearing system allows controlled movement of the pressurized elements in respect to the outer shell.

A device (100, 100′, 200, 300) for filling gas storage tanks (10) comprises a frame (110, 210, 310) and/or a housing, a gas buffer storage tank (120, 220, 320) for a gas which is movably arranged with respect to the frame and/or with respect to the housing, a first valve (130, 230, 330, 331) comprising an inlet, connected to the gas buffer storage tank (120, 220, 320), and an outlet for the connection to a gas storage tank to be filled, and a weighing device (140, 240, 340), connected to the gas buffer storage tank (120, 220, 320), for weighing the gas buffer storage tank (120, 220, 320).

A portable apparatus for oxygen delivery includes a receptacle, a mouthpiece and a tube. In another aspect the mouthpiece includes a first fluid channel for a first fluid and a second fluid channel for a second fluid that is different from the first fluid. In a further aspect, the portable apparatus includes a receptacle, a mouthpiece and a tube in which the mouthpiece includes a teeth engagement portion, a lip engagement portion and a lip protection portion.

A pressure vessel mounting structure (10) includes a plurality of bands (11) made of a composite material cured about the exterior surface (35) of the pressure vessel (30) to form an integral part of the vessel. The bands (11) may be spaced apart from one another to form a crisscrossing helical grid pattern with opposing ends (21) of the bands extending past a respective end (31) of the pressure vessel (30) and toward a longitudinal centerline (33) of the pressure vessel (30) to form a skirt (17). The skirt (17) provides mounting points (15) as well as a vertical standing mount for the vessel.

The present disclosure provides mounting plates having a mounting portion adjacent to a plurality of fastening regions and a flexing portion adjacent to a mounting feature. The fastening regions can be connected to a frame system. The mounting feature can be connected to an end of a pressurized tank. The end of the pressurized tank can move relative to the frame system and the mounting plate can flex such that the flexing portion moves out of the plane of the fastening region to accommodate the motion of the end of the pressurized tank. Connection to the end of the pressurized tank can be provided at a tank collar than can be bonded or threadably connected to the mounting plate via a connection mechanism. The connection mechanism can be an expandable plug or a sleeve that connects to the tank collar.

A pressure vessel includes a boss tail portion including a boss extension portion having a cylindrical shape and a boss flange portion integrally expanding outward in a radial direction along a circumferential direction above the boss extension portion, a liner portion having a container shape in which an accommodation space is formed to accommodate a fluid therein and a bottom is sealed and coupled, through integral insertion-injection molding, along a top surface of the boss flange portion, and a composite cover portion provided to surround an outer surface of the liner portion and to have a bottom end sealed and coupled while surrounding a bottom surface of the boss flange portion and an outer surface of the boss extension portion.

Disclosed is a pressure vessel including a boss extension portion having a cylindrical shape in which a through hole is formed at a central part to pass therethrough and a boss flange portion formed below the boss extension portion and integrally expanding outward in a radial direction along a circumferential direction in which the through hole extends in a vertical direction inward in the radial direction, a liner portion having a container shape in which an accommodation space configured to communicate with the through hole is formed to accommodate a fluid therein while a top is insertion-injection molded and seal-coupled along a bottom surface of the boss flange portion, and a sealing portion seal-coupled to a boundary area between a bottom of the boss flange portion and a top of the liner portion to block a leakage of the fluid accommodated in the accommodation space.

A system for storing fuel includes a support structure supporting at least one fuel tank a predetermined distance above ground. The fuel tank includes an inner tank configured to contain a gaseous fuel, an intermediate tank encompassing the inner tank and defining a first annular space therebetween, and an outer tank encompassing the intermediate tank an defining a second annular space therebetween. The first annular space is filled with a shock-absorbing resin for absorbing structural stresses, while the second annular space is filled with an insulating material providing for fire and ballistic resistance. The intermediate tank is connected to the support structure and to at least one adjacent fuel tank, and prevents the transfer of load to the inner tank.

A container for storing and transporting liquefied gas, having a first, internal reservoir that extends in a longitudinal direction (A) and is configured to store the liquefied gas, a second, external reservoir that is disposed around the first reservoir with a vacuum insulated space between the first and the second reservoir, a third, annular reservoir that is disposed around the first reservoir, between the first and the second reservoir, the third reservoir extending around at least a part of the first reservoir and containing a liquefied gas in order to form a heat shield for thermally insulating the first reservoir, and a device for holding the first and third reservoirs in the second reservoir.
