AI Technical Summary

Problems solved by technology

However, these known solutions do not optimize filling and dispensing performance in conjunction with modular applications
[0005] In particular, the known solutions do not simultaneously guarantee a high level of modularity of the storage equipment used in the filling station (in particular for pressure equalization and / or as a source of compressors) and a good sealing of the circuit, especially in bidirectional use (charging and extracting air flow) case

Embodiment Construction

[0032] figure 1 The valve shown is connected to a (preferably single) orifice of a pressurized fluid storage device, in particular pressurized hydrogen gas, such as a metal or composite storage device structure, for example at a pressure of up to 1100 bar storage device.

[0033] The valve comprises a valve body 2 housing a fluid circuit 3 comprising a first end 4 connected to an orifice of the storage device 1 . For example, the first end 4 of the valve leads to a location for screwing into an externally threaded portion of an internally threaded orifice of the storage device 1 . Alternatively, the first end may of course be connected to a different set of storage devices (eg cylinder racks). In other words, the valve is common to and connected to a plurality of storage devices by a circuit.

[0034] The fluid circuit 3 of the valve comprises at least one second extraction port 5 for connection to a receiving circuit to enable the supply of fluid extracted from the storage...
