Abstract
To compensate for load losses in a downstream part of a line for supplying gas under controlled pressure through a valve which is controlled by a pick-up upstream of the line, the pressure read by the pick-up is supplied by a pressure intake which is formed in a tube extending in the line and which is angularly orientable with respect to the flow of gas delivered. Application for example to systems of supplying breathing gas to the passengers of an airship.
