   Eine zweckmässige Ausführung hiefür besteht darin, dass nicht nur die Einlassöffnungen am Schieberspiegel, wie bei den bekannten Anordnungen, sondern auch die Kanäle für die Haupt-und   Hilf seinströmung getrennt   sind und der Hilfskanal durch ein besonderes Organ abgesperrt werden kann. Das Absperrorgan kann vor oder hinter dem Steuerschieber angeordnet sein. Seine Bewegung

   An expedient embodiment for this is that not only the inlet openings on the slide mirror, as in the known arrangements, but also the channels for the main and auxiliary flow are separated and the auxiliary channel can be blocked by a special organ. The shut-off device can be arranged in front of or behind the control slide. His movement

The same purpose can also be achieved by moving the fixed pivot point of the double lever Z to make the path of the auxiliary slide larger than that of the main slide with the same control data for the main and auxiliary steam supply, 80 there! 3 it influences the steam outlet before the main slide itself takes effect.
