 und von der durchströmenden Gasmenge abhängigen   Druck--p'2--belastet,   wodurch der Regler durch stärkeres Öffnen den gewünschten Ausgangsdruck gewährleistet. 



   Auf der Eintrittsseite ist im Gasstrom ein hohler   Metallkörper--h--vorgesehen,   der durch eine   Hilfsmembran--g-,   deren Nutzfläche mit der Oberfläche des Kegelventils--b--übereinstimmt, abgeschlossen ist. Zur Verbindung des hinter der Hilfsmembran--g--liegenden Raumes--h--dient eine im Ventilschaft--f--verlaufende und mit seitlichen Öffnungen versehene axiale Bohrung Die Hilfsmembran gleicht in dieser Weise die auf das Kegelventil wirkende Gasdruckdifferenz aus. 



   PATENTANSPRÜCHE : 
1. Gasdruckregler mit einem Ventil, dessen Ventilkörper mechanisch mit einer Steuermembran verbunden ist, die auf der einen Seite durch die Kraft einer Steuerfeder, auf der andern Seite durch den zu regelnden

 and the pressure - p'2 - which is dependent on the amount of gas flowing through, whereby the regulator guarantees the desired outlet pressure by opening it more.



   On the inlet side, a hollow metal body - h - is provided in the gas flow, which is closed off by an auxiliary membrane - g - whose useful surface corresponds to the surface of the cone valve - b -. The space behind the auxiliary diaphragm - g - h - is connected by an axial bore in the valve stem - f - provided with lateral openings. In this way, the auxiliary diaphragm compensates for the gas pressure difference acting on the cone valve.

den Ventilkörper (b) bzw. Ventilschaft (f) durchsetzende axiale Bohrung (i) mit dem Inneren eines auf der Eintrittsseite des Reglers angeordneten Metallhohlkörpers (h) verbunden ist, der durch eine der Wirkfläche des Ventilkörpers (b) entsprechende Hilfsmembran (g) verschlossen ist, so dass der auf den Ventilkörper wirkende Gasdruck ausgeglichen ist. The axial bore (i) passing through the valve body (b) or valve stem (f) is connected to the interior of a metal hollow body (h) arranged on the inlet side of the regulator, which is closed by an auxiliary membrane (g) corresponding to the active surface of the valve body (b) so that the gas pressure acting on the valve body is balanced.
