Abstract
The pressure in a high-pressure steam boiler or other pressure fluid tank is occasionally relieved by means of a discharge device having a pressure-relief valve mounted on an ejection conduit opening into a hood connected to a discharge conduit. A break in continuity is provided between this ejection conduit and this hood in order to allow relative movements thereof under thermal expansion; furthermore the ejection conduit opens into the hood through a generally transversely directed nozzle system so that the jet issuing therefrom has a zero or negligible axial velocity component.
