Description

Die Erfindung betrifft eine Ausgestaltung des Regelventite nach Patent 394287 mit dem Zwecke, die Abdichtung des zwischen dem geschlossenem Rohrende von c und1 dem Zylinderboden von e angeordneten Preßluftraumes/ sicherzustellen, ohne daß eine Abdichtung an beweglichen Teilen erforderlich wind. Zu diesem Zwecke ist zwischen c und e eine zusammenpreßbare Metalldose nach Art der bei Barographen üblichen Vakuumdosen vorgesehen, die hier durch das Ventil g entsprechend dem gewünschten Druck mit Preßluft gefüllt ist urid sich je nachdem in dem Leitungsrautn α herrschenden Drucke zusammenzieht oder auseinanderzieht und den Zylinder e verschiebt.The invention relates to an embodiment of the control valve according to patent 394287 with the purpose of ensuring the sealing of the compressed air space arranged between the closed pipe end of c and 1 and the cylinder base of e , without the need for sealing on moving parts. For this purpose, a compressible metal can is provided between c and e in the manner of the vacuum cans customary in barographers, which is filled with compressed air through the valve g according to the desired pressure urid contracts or apart depending on the pressures prevailing in the line duct α and the cylinder e shifts.
