   Ein weiterer und besonderer Vorteil dieser Anordnung ist, dass die beiden Rollen

 übertragung der im Eintrittsdampf befindlichen Ventilspindel auf die Spindelführung selbst bei Anwendung der höchsten Heissdampftemperatur keinen nennenswerten Einfluss auf die Zunahme der Entfernung der beiden Rollen ausüben kann, was insbesondere aus dem Grunde von   grösster Wichtigkeit ist, weil   die Steuerung im kalten Zustande nicht klemmen, im warmen Zustande aber, um richtig zu funktionieren und kein Klappern und Schlagen zu verursachen, kein Spiel aufweisen darf. 



   Mit Rücksicht auf Ungenauigkeiten in der Herstellung und die Abnützung wird es

 ausgeführt werden. So kann der Drehpunkt Bs der Schubkurve D in der Ventilhaube, auf der einen oder anderen Seite der Spindelführung oder, bezüglich der Lage gegenüber den Rollen, unterhalb oder oberhalb derselben gelagert worden. Die günstigste Gestaltung der

   Auch kann der Drehzapfen B3 in der Spindelführung F und die Eröffnungs- und Schlussrolle in der Vontilhaube gelagert werden, bei genau der gleichen Ausgestaltung der Schubkurve D.

   Another and special advantage of this arrangement is that the two roles

 Transfer of the valve spindle located in the inlet steam to the spindle guide, even when using the highest hot steam temperature, cannot have any notable influence on the increase in the distance between the two rollers, which is particularly important because the control does not jam when it is cold, but when it is warm However, in order to function properly and not to cause rattling and hitting, it must not have any play.



   Taking into account inaccuracies in manufacture and wear and tear, it will

   The pivot pin B3 can also be stored in the spindle guide F and the opening and closing rollers in the Vontile hood, with exactly the same design of the thrust curve D.
