Druckregler zum Erzeugen eines geregelten Steuerdrucks für ein membrangesteuertes Gasventil

摘要

The servo pressure regulator provides an output control pressure for a membrane-controlled gas valve via an electromagnetic linear drive (3,4,5), simultaneously acting as the switching drive for a switching valve (8,9) preceding the pressure valve. A min gas pressure channel branches off immediately after the switching valve in the gas flow direction and is provided with a pressure setting device (17), with a throttle position between the min gas pressure channel and the chamber of the pressure regulator providing the regulated control pressure for the gas valve.
