An anti-fire safety system for a transport vehicle has one or more storage tanks storing hydrogen. The system includes a first hydrogen-releasing system, which is configured to release outside the vehicle hydrogen contained in at least one of the storage tanks. The system also includes a second release system, which is arranged to intervene and bypass the first hydrogen release system under predetermined operative conditions. The second release system is configured to transform by a chemical reaction, at least a part of the bypassed hydrogen flowing outward from at least one storage tank, into at least one different substance.

A pressure vessel stores fuel. The pressure vessel includes a liner, a fiber-reinforced layer, at least one end piece, and at least one outlet. The fiber-reinforced layer surrounds the liner, at least in some regions. The end piece is covered by the fiber-reinforced layer, at least in some regions. The at least one outlet is used to carry fuel that has collected in a boundary layer between the liner and the fiber-reinforced layer and is to be drained. The outlet surrounds the end piece, at least in some sections. The outlet is arranged and formed in such a way that the fuel to be drained escapes from the boundary layer into the outlet.

The invention provides a device for protecting a high-pressure gas tank of a motor vehicle. The device includes at least one heat-conducting plate and a thermal triggering unit. The heat-conducting plate has a distal region and a proximal region. The proximal region is arranged immediately adjacent to the thermal triggering unit and the distal region is arranged at a distance from the thermal triggering unit. The heat-conducting plate may be shaped so that it tapers from the distal region to the proximal region. The proximal region itself may be shaped in a tapering fashion. The heat-conducting plate may include heat-conducting fibers.

The invention relates to a safety valve comprising a valve body with a guide bore which defines a longitudinal axis, a first opening which is formed on a base of the guide bore, and a second opening which is formed at a distance to the base along the longitudinal axis and which extends along a radial direction extending transversely to the longitudinal axis; a valve needle which is movably mounted in the guide bore of the valve body in an axial direction and which comprises a seal surface facing the first opening; a compression spring device with a spring that is compressed by a deflection and thereby biases the valve needle along the longitudinal axis into a seal position, in which the seal surface of the valve needle seals the first opening; and a thermally activatable trigger unit which has an extension along the longitudinal axis, said extension being greater than the deflection, and which is designed to collapse when a trigger temperature is reached, wherein the compression spring device is supported against the trigger unit.

A composite storage tank may include a wall structure including at least three regions including an inner region, an outer region, and at least one permeation barrier. Another region may be optionally incorporated for venting potential permeation of fluids. The at least one permeation barrier and/or the venting layer may be strategically positioned between the inner region and the outer region to reduce or at least partially prevent fluid permeation of the inner region or the outer region. A vehicle may include such a composite storage tank. Methods of forming a composite fluid storage tank may include forming an inner composite region, applying a permeation barrier to an outer surface of the inner composite region, forming an outer composite region, and curing the inner composite region and the outer composite region with the permeation barrier to form the composite fluid storage tank.

The invention relates to an indoor safety device for a liquefied fuel gas system, the system comprising a storage device storing liquefied fuel gas; a vent member arranged in fluid communication with the gas inside the storage device; and a safety valve arranged to evacuate gas when the pressure inside the storage device exceeds a predetermined first value, the safety device comprising: a vent coupling; a pressure relief valve arranged downstream of the vent coupling; and a conduit for conveying gas, adapted to be connected to the pressure relief valve, the safety device being removably connected to the system by connecting the vent coupling to the vent member, wherein the pressure relief valve is configured to release gas when the pressure inside the storage device exceeds a predetermined second value, lower than the first value.

A high pressure tank apparatus includes a high pressure tank, a leaked fluid container, and a supply/discharge side discharge flow path. The high pressure tank includes a liner made of resin, a reinforced layer that covers an outer surface of the liner, an insertion member that has formed therein a supply/discharge hole capable of communicating with an inside of the liner and the supply/discharge flow path; and a supply/discharge side cap in which are formed an insertion hole through which the insertion member is inserted and a supply/discharge side draw-out hole that draws out the fluid interposed between the liner and the reinforced layer. The supply/discharge side discharge flow path guides a temporarily released fluid that is the fluid drawn out via the supply/discharge side draw-out hole to a discharge region.

A high pressure tank includes: a resin liner for containing a fluid; a reinforced layer covering an outer surface of the liner; a cap including a supply/discharge hole to supply and discharge the fluid to and from the liner; an isolation wall member; and a communication unit. The cap includes a cylindrical protrusion having the supply/discharge hole formed therein. An opening is formed in the reinforced layer to expose the protrusion. The isolation wall member encloses the protrusion and the opening, and forms a closed space. The communication unit communicates with the closed space.

A motor vehicle has at least one pressure vessel for storing storage medium, preferably fuel, at least one pressure relief device for pressure relief of the at least one pressure vessel, and at least one opening through which storage medium flows out during a pressure relief.

A combustible gas supply unit is for supplying compressed combustible gas to a dispenser. The combustible gas supply unit includes a high pressure gas facility for handling compressed combustible gas, a base plate having the high pressure gas facility installed thereon and a barrier supported by the base plate to surround at least a part of an outer periphery of the high pressure gas facility. A barrier is shaped to surround at least a part of an outer periphery of the high pressure gas facility and includes a part to be supported by a base plate having the high pressure gas facility installed thereon.
