摘要:
A cylinder (10) for storing pressurized fluid is provided, comprising a hollow body(12) formed integrally with a closed bottom end (14) and a closed upper end (16), a valve (20, 200) having a valve body (24, 205) and an actuator (22, 220), said valve (20, 200) being arranged at said upper end (16) for allowing gas charging and gas discharging, respectively, wherein said valve (20, 200) is mounted on the inside of said cylinder (10) such that the interior surface of said upper end (16) is sealed against said valve body (24,205), and such that said actuator (22, 220) is extending outside said cylinder (10).
摘要:
A device and method for extracting tubular structures are provided. An incision is made at a proximate and at a distal end of a tubular structure. An extracting device is inserted into and passed through a tubular structure until the operational head of the device extends past the distal incision. An actuator on the handle of the device is actuated, longitudinally extending the operational head of the device. The edge of a tubular structure is positioned axially in the mouth of a hook wire on the operational head. The actuator on the handle is released and the hook wire engages and captures the tubular structure. The user manually pulls the tubular structure, invaginating and removing it.

A gas cylinder has a circular-cylindrical shell which is closed on one end by a bung assembly having a connection hole extending along a longitudinal axis direction of the cylinder. The bung assembly has an auxiliary hole extending in a direction which is inclined with regard to a longitudinal axis direction of the cylinder. The connection hole is for introducing gas into and retrieving gas from said gas cylinder, while the auxiliary hole cooperates with a sensor device for measuring a parameter indicative of the filling level of the gas in the cylinder.The auxiliary hole extends in a direction intersecting the central longitudinal axis direction of the gas cylinder and may have an inclination such that the auxiliary hole extends in a direction perpendicular to the central longitudinal axis direction of the gas cylinder. The auxiliary hole may be a through hole or a blind hole.

摘要:
Dispositif de sécurité formant une soupape de libération d'un gaz sous pression, comprenant un corps définissant un canal (1) d'écoulement de gaz s'étendant entre une première extrémité amont (11) destinée à être mise en contact avec une source de gaz (G) sous pression et une seconde extrémité aval (12) destinée à être mis en contact avec l'atmosphère extérieure, le dispositif comprenant un bouchon (3) situé sur le canal (1) pour empêcher l'écoulement du gaz entre l'extrémité amont (11) et l'extrémité aval (12) en situation normale, le bouchon (3) étant fusible et/ou frangible pour libérer le passage pour le gaz en cas de situation dangereuse lors d'une pression et/ou une température excédant un seuil déterminé, caractérisé en ce que le dispositif comprend une réserve (4) de gaz instable à décomposition exothermique qui est mis en communication avec le gaz (G) sous pression libéré lors de la fusion/rupture du bouchon (3).
摘要:
A Dewar system is configured to liquefy a flow of fluid, and to store the liquefied fluid. The Dewar system is disposed within a single, portable housing. Disposing the components of the Dewar system within the single housing enables liquefied fluid to be transferred between a heat exchange assembly configured to liquefy fluid and a storage assembly configured to store liquefied fluid in an enhanced manner. In one embodiment, the flow of fluid liquefied and stored by the Dewar system is oxygen (e.g., purified oxygen), nitrogen, and/or some other fluid.

A gas cylinder (1) comprising a cylinder body (2) with a tubular wall (5) having at least a first tubular portion (11) that is enlarged, and at least a second tubular portion (12) that is adjacent and narrowed relative to the first tubular portion (11).
摘要:
The invention provides a hydrogen dispensing system comprising: a feed vessel for storing liquid hydrogen having an inlet and an outlet; a flash drum having an inlet and an outlet; a dispenser for dispensing gaseous hydrogen at a pressure of greater than 300 bar, having an inlet and an outlet wherein the feed vessel outlet is in fluid communication with the flash drum inlet, the flash drum outlet is in fluid communication with the dispenser inlet and there is no compression apparatus between the feed vessel outlet and the dispenser outlet. The invention also provides a method of providing gaseous hydrogen to a vehicle.
摘要:
A fluid pressure regulator insertable over a valve in a fluid container, its use method and a needle subassembly for said regulator, wherein the regulator comprises a knob for allowing and regulating fluid flow; a ratchet interconnected to said knob; a revolver interconnected to said ratchet, wherein the ratchet controls the position of said revolver and wherein said revolver controls the fluid flow by means of the blocking of an auger; a diffuser subassembly that controls fluid flow towards said revolver my means of a seal and at least two chambers; a spring to control the displacement of said diffuser subassembly; and a needle subassembly interconnected with said diffuser subassembly to allow fluid output from said valve.
