Récipient de fluide sous pression, notamment bouteille de gaz sous pression, comprenant un corps (1) formant un volume de stockage étanche pour du fluide, une première extrémité du corps (1) comprenant un orifice (2), une seconde extrémité du corps (1) comprenant pied (3) fixé sur le corps (1), le corps (1) étant composé d'un matériau métallique, d'un alliage métallique ou d'aluminium, caractérisé en ce que le pied (3) comprend un matériau métallique, un alliage métallique ou un alliage d'aluminium ayant une électronégativité selon l'échelle de Pauling supérieure à l'éléctronégativité du matériau composant le corps (1). L'invention concerne également un procédé de fabrication d'un tel récipient.
Abstract:
A stand for supporting a pressure vessel includes a body having an upper wall and a sidewall extending downwardly from the upper wall, an aperture defined in the upper wall configured to permit passage therethrough of a fluid conduit, the fluid conduit being in fluid communication with the pressure vessel, and a locking element provided in connection with the body configured to engage the fluid conduit when in a locked position to inhibit removal of the stand from the pressure vessel.
Abstract:
The present invention provides a cryogenic container (10) comprising walls (20) and a base (30), said walls comprising: a first liquid barrier layer (50); a second liquid barrier layer (100); one or more spacer elements (150), disposed between the first and second liquid barrier layers (50, 100), to separate the first and second liquid barrier layers (50, 100), thereby providing an annulus (200); one or more fluid vents (250), in direct fluid communication with the annulus (200) for venting fluid from the annulus (200), wherein at least one of the vents (250) is connected to a pressure differential device (320); sealing means (260) to contain the annulus (200); a pressure measuring device connected to the annulus for monitoring the pressure in the annulus over time; and a comparator for comparing at least two pressure measurements from the pressure measuring device.
Abstract:
A fluid storage and delivery apparatus may include a fluid container and a vent valve for releasing fluid from the fluid container. The vent valve may include a vent valve body formed from a single piece, and a vent valve inlet and vent valve outlet coupled to the single-piece vent valve body. The apparatus may also include one or more coupling members at least partially defining a fluid passageway between the vent valve and the fluid container.
Abstract:
A fluid storage and delivery apparatus includes a fluid container, a first apparatus component, and housing. One or more support members may be coupled to the housing and configured to secure the first apparatus component physically separate from the fluid container. The first apparatus component may be indirectly coupled to the fluid container by one or more coupling members at least partially defining a fluid passageway between the first apparatus component and the fluid container.
Abstract:
Il est proposé un réservoir (1) pour le stockage d'un gaz, le gaz étant stocké par sorption sur un composé. Le réservoir comprend une alvéole (2) apte à contenir le composé. L'alvéole est telle qu'elle comprend des moyens d'absorption de chocs (3).

Abstract:
Ein Kraftfahrzeug-Außentank (2) für einen in einem innerhalb des Außentanks (2) liegenden Innentank (3) befindlichen kryogenen Kraftstoff ist zur Platz- und Gewichtseinsparung dadurch gekennzeichnet, dass er in Flachbauweise ausgebildet ist, insbesondere als Parallelepipet gestaltet ist, und dass ebene Seitenwände (13) des Außentanks (2) zumindest teilweise in Sandwichbauweise ausgeführt oder mit Sandwichplatten (9) verstärkt sind.
Abstract:
Ein Behälter für kryogene Kraftstoffe in abgeflachter Bauweise, der von einer Superisolierung umgeben ist, soll automatisierbar und preisgünstig an verschiedene Fahrzeugmodelle bzw Einbausituationen anpassbar sein und sowohl mechanischen, als auch thermischen Belastungen standhalten. Dazu ist er aus mehreren gleichartigen in verschiedener Konfiguration zueinander angeordneten geraden und geschlossenen Profilen (4, 5) zusammengesetzt, welche parallel zueinander angeordnete gerade Hohlprofile sind, deren zumindest eine äußere Begrenzungswand (14, 15, 16, 17) zu einer äußeren Begrenzungswand (18) eines benachbarten Profiles einen Funktionsabstand hält und an deren offene Enden (28, 29) beiderseits jeweils eine gemeinsame Kappe als gemeinsamer Verbindungsraum der Profile (6, 7) anschließt. Die Verstärkungen (24, 25) sind bei rechteckigen Profilen vorzugsweise Seitensymmetralen deren Aussenwände (14, 15,16, 17).
Abstract:
A large, box-like polygonal tank (30) for storing liquefied gas on land or on ground based structures and a method of constructing the tank. The tank is comprised of an internal, truss-braced, rigid frame (31), having a cover (40) on the frame for containing the stored liquid within the tank. The internal, truss-braced frame allows the interior of the tank to be contiguous throughout while compensating for the dynamic loads caused by the "sloshing" of stored liquid which, in turn, is due to the short excitation periods caused by seismic activity.
