Abstract:
The invention relates to a storage bag for temporarily accommodating the liquefied petroleum gas, to a liquefied petroleum gas storage, to a fuel supply system, and to an assembly for buffering a liquefied petroleum gas (LPG) in a liquefied petroleum gas storage. The storage bag is arranged for temporarily accommodating the liquefied petroleum gas, having a fuel collection volume and a supply unit for allowing liquefied petroleum gas from the storage to enter into the fuel collection volume. The assembly can comprise a fuel pump having a pump housing and an inlet connected to the fuel collection volume. According to the invention a fuel pump and storage bag connection is arranged to allow feeding of the assembly the one after the other through an opening of the liquefied petroleum gas storage. According to the invention the storage bag comprises a jet pump.
Abstract:
Subject of the invention is pressure tank, especially three-bottoms tank, creating beneficially toroidal tank, comprising connected bottoms, equipped with connector pipes for installation, brackets for fastening the tank and cover, type plate, equipment cover, inner bottom, inner shell, divider and is characterized by that the outer, upper bottom (1) together with outer, lower bottom (2) create outer tank shell, whereas inner bottom (4) is connected with the inner shell (3), creating the central, inner part (S) of the tank, and connector pipes (9, 9a, 9b and 14) and flow connectors (15, 15a) have on their length two zones: zone A –with walls of increased thickness and zone B –with walls of reduced thickness, beneficially on the whole circumference of connector, whereas the wall thickness in zone B is between 0,5 up to 1,7 of the thickness of tank elements when the wall thickness is between 0,01 up to 2,9 mm and 0,3 up to 1,4 for walls thick above 2,90 mm.
Abstract:
An end fitting for a cylindrical high pressure vessel made from components all having thin walls, thereby tripling the practical diameter of such pressure vessels. The end fitting includes a toroidal shell defining a hole; centrally disposed piece for closing the hole comprising a pipe and a center end fitting and structural members. In a first embodiment, the structural members comprise slices of an end of the pipe welded to the outer cylindrical wall of the vessel. In a second embodiment, the structural members are plates connecting the pipe to the outer cylindrical walls. In the third embodiment, the plates connect an extension of the outer cylindrical wall beyond the toroidal shell to an extension of the outer cylindrical wall of the pressure vessel. The center end fitting may be hemispheric or ellipsoidal.
Abstract:
The subject of invention is the pressure tank, especially four-bottoms tank, especially the tank for volatile and liquid pressure gases as well as liquids, used in vehicles, machines, stationary and mobile devices. Pressure tank, according to the invention, creating beneficially toroidal tank, containing connected together bottoms, equipped with connector pipes for fittings, brackets for fixing the tank and cover, cover for fittings, central coupler with holes and central bush is characterized in that it comprises at least four tightly connected bottoms, where the outer, upper bottom (1) with outer, lower bottom (2) create the outer tank shell, whereas the inner, upper bottom (3) is connected to inner, lower bottom (4) through the central bush (5) and beneficially the outer shell (6) with holes (7) create the central coupler (A), containing the additional work space (B).
Abstract:
The present invention is a tank suitable to contain high pressure fluids, especially for compressed natural gas used for automotive purposes. The tank has a discoid shape to be easily placed on board of vehicles. The tank comprises a sealed internal core and an external coating made through a twisted coats fiber wrapping of composite material with a very high mechanical tensile resistance. According to some executive variants, the tank internally comprises a reinforcing structure made up of a plurality of elements welded in contact with the internal surface of the core.

Abstract:
Bei einem Treibstofftank, der insbesondere zur Lagerung kryogener Treibstoffe zum Beispiel von Raumflugkörpern dient und der mit einem als Fördermedium dienenden Treibgas betrieben wird, erfolgt die Separation des Treibstoffes vom Treibgas in einer Treibstoff entnähme Vorrichtung mittels Sieben und unter Ausnutzung hydrostatischer Kräfte und Kapillarkräften. Die Entnahmevorrichtung besitzt die Form eines wiederbefüllbaren Reservoirs, das in der Nähe des Tankbodens außerhalb der Tankschale am Bodenbereich des Treibstofftanks angebracht ist und das über eine Anzahl von Löchern mit dem Inneren des Treibstofftanks verbunden ist. Die Entnahmevorrichtung selbst besteht aus einem doppelwandigen Gehäuse und ist zusätzlich thermisch isoliert. Kapillarbleche und zusätzliche Verstrebungen sind in L-Form in das Reservoir eingebracht. Ferner ist zur weitgehenden Unterbindung des Eindringens von Gas aus der Treibstoffleitung ein zylinderförmiges, plissiertes Sieb am Ende der Treibstoffleitung angebracht.
Abstract:
A hydrogen storage and delivery system is provided having an orifice pulse tube refrigerator and a liquid hydrogen storage vessel. A cooling system, coupled to the orifice pulse tube refrigerator, cools the vessel and abates ambient heat transfer thereto in order to maintain the liquid hydrogen in the vessel at or below its saturation temperature. Hydrogen boil-off, and the necessity to provide continuous venting of vaporized hydrogen are minimized or avoided. In a preferred embodiment, the hydrogen storage vessel has a toroidal shape, and the pulse tube refrigerator is a two stage pulse tube refrigerator and extends within a central void space defined at the geometric center of the toroidal storage vessel. Also in a preferred embodiment, the cooling system includes first and second thermal jackets, each having a substantially toroidal shape and enclosing the storage vessel, wherein each of the thermal jackets is thermally coupled to one the first or second stages of the pulse tube refrigerator in order to cool the vessel and to abate ambient heat leak thereto. The hydrogen storage and delivery system is particularly suitable for use in vehicles, such as passenger automobiles.
