Abstract:
The invention concerns a tank formed by a plurality of elementary tanks such as tubes (20) connected in parallel to at least a manifold (30, 32) and comprising closing means in the form of valves for isolating any one of the elementary tanks in response to a fall of pressure in it.
Abstract:
The invention relates to a station (1) and method for filling a tank (7) with a fuel gas. Said station includes at least one fuel gas source store (3) and a gas transfer system (8) having a first upstream end connected to the source store(s) (3) and a second downstream end that is in fluid communication with the tank (7). The gas transfer system (8) includes at least one control valve (9, 10), characterized in that the at least one source store (3) includes a rigid outer wall and a flexible sealing wall (2) that is arranged inside the space defined by the rigid outer wall. The flexible wall (2) defines a storage space for the fuel gas. The first upstream end of the system (8) is connected to the storage space defined by the flexible wall (2). The at least one control valve is also characterized in that the space located between the flexible wall (2) and the outer wall is connected to a system (12, 13) for transferring liquid into the source store (3) in order to fill or extract the liquid in the source store (3) and control the pressure in the store (3) when filling and/or extracting fuel gas within the sealing wall (2).
Abstract:
Die Erfindung betrifft eine Konstantdruckspeichereinheit umfassend mindestens einen Konstantdruckspeicher (A, B, C, D), welcher durch einen verschiebbaren Trennkolben (11A, 11B, 11C, 11D) in zwei Bereiche getrennt ist, mindestens eine Flüssigkeitspumpe (9) zur Förderung einer Flüssigkeit (1) und mindestens einen Flüssigkeitsspeicher (4), wobei die Konstantdruckspeicher (A, B, C, D) auf der Seite auf der der Bereich ist, der für eine Flüssigkeit vorgesehen ist, mit mindestens einem weiteren Behälter (E), einem Sicherheitsbehälter, in Verbindung stehen. Dieser ist durch einen beweglichen Trennkolben (11E) in zwei Bereiche geteilt, wovon der eine Bereich mit dem mindestens einem Konstantdruckspeicher (A, B, C, D) und der Flüssigkeitspumpe (9) in Verbindung steht und der andere Bereich ein Pufferfluid (5) enthält.
Abstract:
A fuel cell valve assembly for a fuel cell for combustion powered hand tools, said valve assembly (22) comprising a valve body, a valve stem (28) movcably disposed in the valve body and movable between a closed position in which, in use, fuel is prevented from flowing from the fuel cell and an open position in which fuel can flow from the fuel cell into a first fuel receiving passage that is defined by the valve stem and a valve stem cap (38) disposed on said valve stem, said valve stem cap having a second fuel receiving passage (46) that is in flow communication with said first fuel receiving passage and is provided with a plurality of exit holes (52) that each extend transversely of said second fuel receiving passage.
Abstract:
Cryogenic tank intended for containing a cryogenic fluid, in particular a space launcher tank intended to contain a cryogenic propellant, comprising a wall (1 ) defining a storage volume for the cryogenic fluid, characterized in that it includes at least one partition (2) located in the storage volume, said partition (2) defining an upper volume (VS) and a lower volume (Vl) for the fluid in the tank (1) communicating via at least one opening (3) formed in the partition (2), in order, on the one hand, to allow the liquid to flow under gravity from the upper volume (VS) into the lower volume (Vl) and, on the other hand, to prevent the fluid from rising from the lower volume (Vl) into the upper volume (VS) under the action of acceleration forces.
Abstract:
There is provided a membrane material for a gas folder having abrasion resistance and flex resistance usable as a gas holder, in addition to strength of a base fabric, and having high gas barrier properties. A membrane material for a gas holder, which is used in a gas holder for storing or recovering gas, comprising at least 4 layers of a protective layer, a base fabric layer, a gas barrier layer and a protective layer laminated in this order.
Abstract:
A flexible membrane gas accumulator, in particular for storing biogas, comprising a first membrane (1) at least partially defining a gas accumulation chamber (C1) and a second membrane (2) partially defining a pressurizing chamber (C2) adjacent to said accumulation chamber (C1); further comprising means (3) for leading and taking gas, means (4) for pressurizing said pressurizing chamber (C2), means (5) for hooking said membranes and means (6) for detecting the volume of said accumulation chamber (C1) in which a third membrane (7), impermeable to gas and fixed in an impermeable manner at least to said second membrane (2), for defining, in co-operation with the latter, said pressurizing chamber (C2).
