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.

A fluid system for a vehicle is provided. The fluid system is configured to couple to a chassis of the vehicle. A frame assembly of the fluid system is configured to couple with the chassis directly or with another component that is coupled, directly or indirectly, with the chassis. A cowling of the fluid system can enclose a fuel pressure vessel and an auxiliary fluid vessel. The auxiliary fluid vessel is configured to be placed in fluid communication with the component powered or operated by the fluid therein.

A method of storing and using natural gas (NG) in a vehicle includes selecting a vehicle having an NG tank for fueling an engine of the vehicle. The tank service pressure rating is 3600 psi (pounds per square inch) and an NG adsorbent is in the tank. A first quantity of NG is transferred into the tank from a first source having a first source pressure less than 725 psi. The adsorbent adsorbs a portion of the NG. After transferring the first quantity of NG, the engine is operated until NG is desorbed and consumed by the engine. NG is transferred into the tank from a second source to fill the tank to a second tank pressure of about 3600 psi. The adsorbent adsorbs some of the NG. After transferring the second quantity of the NG, the engine is operated until NG is desorbed and consumed by the engine.

A hydrogen storage system comprises a substantially cylindrical reservoir having at least one axial neck accommodating a drawing device, a substantially parallelepipedal structure surrounding the reservoir, and a cage supporting the reservoir while gripping around the drawing device. The cage is secured to the structure with at least one interface part that is configured to deform and/or rupture in the event of impact in order that the cage remains secured to the drawing device and transmits little or no force to the drawing device.

The invention relates to a gas discharge device (1) for a vehicle powered by compressed gas, comprising: —a gas manifold (11) having a hollow body and comprising: ⋅at least one port (12) configured to be in fluid communication with a compressed gas tank; and ⋅an opening (13) for discharging gas into the atmosphere; —a pipe (14) configured to connect the port (12) to a compressed gas tank; the pipe (14) being freely translatable in the port (12) to enable a first end (141) of the pipe (14) to move translationally along an axis (A) in the port (12).

A fuel system is provided that includes a fuel system frame and in some cases access steps. The frame can be mounted to a vehicle frame rail. Bracket assemblies can be coupled to the fuel system frame at a plurality of positions. The fuel tank can be mounted at neck portions thereof and can be supported on the frame rail between the neck portion, e.g., spaced a distance from the neck portions in a longitudinal direction of the fuel system. The access steps can be non-rectangular to provide a wide stepping portion even if the fuel system includes large tanks. The steps can be directly supported by an outside surface of the tank.

The present invention is directed to a new concept for a large-scale high-pressure Honeycomb Set Tank in an ISO container and for its manufacturing facilities. A process for manufacturing a plurality of honeycomb cells with a high degree of accuracy is also provided.

The invention relates to a gas supply device including a supporting frame (2) housing a plurality of cylinders (3) connected such as to form a circuit (4, 5) including a first coupling end (6) connected to the cylinders (3) via a first isolation valve (7) and a second separate coupling end (8) that is connected to the cylinders (3) via a second isolation valve (9) and a pressure release valve (10), the supporting frame (2) including an interface panel (20) comprising at least one opening enabling a user to access the circuit (4, 5), characterized in that the device comprises a member (16) for manually controlling the second isolation valve (9) including a pivoting lever, and in that the interface panel (20) includes a slot (21) for accessing the lever (16), said lever (16) being movable between a first position in which the lever (16) is in the plane of the interface panel (20) or set back from the latter within the volume of the frame (2) and a second position in which at least one portion of the lever (16) projects relative to the interface panel (20) through the slot (21).

The invention pertains generally to a handle which spans across two cylinders, each cylinder having a pair of collars, in which mating engagement is secured by various fastening approaches employing the peripheral ends of each handle.

Provided is a tank holder capable of suppressing a necessary dedicated space. A tank holder to hold a tank includes: a belt-shaped band that is arranged along an outer circumference of the tank, the band being provided with a plurality of pressing elements that protrude to press a surface of the tank and elastically deform.
