Description
KAISERLICHESIMPERIAL
PATENTAMTPATENT OFFICE
Das Sicherheitsventil α ist mit der Scheibe b verbunden, welche einen zwischen beiden liegenden Raum c begrenzt und so angebracht ist, dafs der zum Ventil α gelangende Dampf an ihr vorbeigeht. Bei durch Drucküberschreitung hervorgerufenem Heben des Sicherheitsventiles entsteht ein Druckunterschied ober- und unterhalb der Scheibe, wodurch dieselbe nach oben gedrängt wird; der mit hohem Druck nach oben gehende Dampf wirkt bei seiner Strömung auf die Scheibe b, so dafs ein besonders hoher Hub des Sicherheitsventiles herbeigeführt wird.The safety valve α is connected to the disk b , which delimits a space c between the two and is attached in such a way that the steam reaching the valve α passes it. When the safety valve is raised due to the pressure being exceeded, a pressure difference arises above and below the disc, which pushes the disc upwards; the steam, which goes upwards at high pressure, acts on disk b as it flows, so that a particularly high lift of the safety valve is brought about.
