Abstract
The invention relates to a valve device of the cylinder valve type, comprising a filling coupling () connected directly to the inlet () of the valve without passing via the valve shut-off device (). A filtering element () is positioned in a chamber at the intersection between the inlet to the valve and the device for shutting-off the valve. This allows the filter to be arranged optimally from the accessibility point of view and also from the gas flow point of view. Specifically, the filter is arranged in the chamber in such a way as to filter the stream of gas flowing towards the outlet () of the valve via the shut-off device, thus protecting the latter, and also in such a way as not to filter the stream of filling gas flowing from the filling connector of the valve towards the inlet.
