A high pressure tank includes: a container body including dome parts; a reinforcement layer provided on an outer surface of the container body and including fiber-reinforced resin; and a protective member provided on an outer surface of the reinforcement layer, wherein the protective member includes a first layer disposed at the outer surface of the reinforcement layer that covers at least a part of the dome parts, and a second layer disposed outward of the first layer. The first layer is more deformable due to the same load applied from the outside than the second layer is.

A high-pressure gas tank module may include: a gas tank which stores high-pressure gas, the tank including a cylindrical side wall extending along a center axis of the tank, and an end wall located at an end of the side wall, wherein the end wall is curved outward in a dome-shape; a protector fixed on an outer surface of the end wall; and a boss located on the center axis and fixed on an inner surface of the end wall. The boss includes a joining surface joined to the inner surface, the protector includes a facing surface facing the end wall, wherein the facing surface includes a joining area joined to the outer surface and a non-joining area extending along the outer surface from the joining area toward the side wall, and the joining area faces the joining surface with the end wall interposed therebetween.

A high-pressure gas tank connection structure including: a tank main body; a tank side connector; a connection side connector; and a valve body, the valve body being provided further toward a deep side along the axial direction of the tank main body than the tank side connector, the valve body being urged toward the connection side connector, and, in a case in which the valve body is pushed by a distal end of the convex portion in a state in which the convex portion is joined with the concave portion, the valve body being opened from a closed state, and communicating the interior of the tank main body with the exterior to the tank main body.

An energy storage assembly for a motor vehicle, including a traction battery for storing electrical energy. A flexible pressure element, which is filled with gas or liquid is disposed on the outside of the traction battery or on the inside of a covering component for the traction battery, the gas or the liquid is contained at atmospheric pressure within the flexible pressure element. A pressure sensor is connected to the flexible pressure element, and by which collision-induced pressure fluctuations in the flexible pressure element can be sensed.

An air reservoir system is provided that includes a switchable valve to direct input air to an air reservoir, or stored air in the air reservoir to a firing pathway. Various example embodiments of the present general inventive concept may also include an air-saver system to maintain a minimum air pressure in the air reservoir during a firing operation.

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.

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.

A portable gas cylinder assembly is disclosed which includes a gas cylinder having a central axis and a protective shroud configured to encase the gas cylinder and including opposed half-sections mechanically connected to one other along a vertical plane intersecting the central axis of the gas cylinder.

A container includes first and second hollow shells respectively including first and second inner surfaces to receive a portion of a pressure vessel (PV). The first hollow shell includes a fiber layer that is and at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the first inner surface and disposed between the first inner surface and the fiber layer. The second hollow shell includes a fiber layer that is at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the second inner surface and disposed between the second inner surface and the second fiber layer. The first and second hollow shells are attachable to one another to define a volume for at least partially enclosing the PV.

A fuel transfer station may provide for the refilling of fuel canisters providing fuel to combustion powered equipment. The fuel transfer station may include a base, a frame coupled to the base, a first connection port and a second connection port provided in the base, and fluid flow lines connecting the first connection port and the second connection port. A supply tank may be supported by the frame and detachably connected to the first connection port. A fuel canister to be refilled may be detachably connected to the second connection port. Fuel contained in the supply tank may be selectively supplied to the fuel canister through the fluid flow lines in response to a pressure gradient drawing the fuel into the fuel canister.
