. Diese Ventilsteuerung, die sich auch für Umsteuerung eignet, hat folgende Anordnung:. This valve control, which is also suitable for reversing, has the following arrangement:
Der Regulator steht auf der Mitte des Dampfcylinders, wird von der Kurbelwelle aus in Bewegung gesetzt und macht mit dieser gleich viel Umdrehungen. In der Zeichnung ist eine Bewegungsübertragung mittelst Kette und gezahnten Kettenrollen angedeutet, jedoch kann auch statt deren ein Zahnrädergetriebe angewendet werden. Auf der Regulatorwelle t ist die Steuerscheibe a befestigt; in dieser bewegt sich radial bei Aenderung der Regulatorstellung der Knaggen b durch Vermittelung des Winkelhebels de, an den auf der entgegengesetzten Seite ein Druckcylinder / angehängt ist.The regulator stands in the middle of the steam cylinder, is set in motion by the crankshaft and makes the same number of revolutions with it. In the drawing, a transmission of movement by means of a chain and toothed chain rollers is indicated, but a gear transmission can also be used instead. The control disk a is attached to the regulator shaft t; in this, when the regulator position changes, the lug b moves radially by means of the angle lever de, to which a pressure cylinder / is attached on the opposite side.
Die Einströmungsventile k werden durch deren Stangen i Z1 mittelst der Hebel h It1 wechselweise geöffnet, sobald der Knaggen b über die Rollen g gi gleitet und dieselben niederdrückt. Die verschiedenen Cylinderfullungen werden durch die Form und Stellung des Knaggens erreicht.The inflow valves k are alternately opened by their rods i Z 1 by means of the lever h It 1 as soon as the lug b slides over the rollers g gi and presses them down. The different cylinder fillings are achieved through the shape and position of the lug.
Das Oeffnen und Schliefsen der Ausströmungsventile r erfolgt wechselweise durch die Be wegung der Stangen q q, und ο in Verbindung mit den Hebeln Pp1 und n, welche durch das auf der Steuerscheibe α befindliche Kreissegment / bewirkt wird, sobald dieses unter der Rolle m hingleitet.The opening and closing of the outflow valves r takes place alternately through the movement of the rods qq, and ο in connection with the levers Pp 1 and n, which is effected by the circular segment / located on the control disk α as soon as it slides under the roller m.
Je nachdem die Drehung der Maschine erfolgen soll, ist der Knaggen b in der gezeichneten oder in der entgegengesetzten Lage anzubringen. Wird statt der Deckplatte c, welche den Knaggen b in der Scheibe α hält, ein zweiter, gleichgeformter Knaggen angewendet und mit ersterem fest verbunden, jedoch so, dafs der eine nach rechts, der andere nach links steht, und werden ferner die Ventilhebel doppelt und der Lage der Knaggen entsprechend angebracht, so ist dadurch eine Umsteuerung der Maschine zu erreichen.Depending on the rotation of the machine, the lug b is to be attached in the position shown or in the opposite position. If, instead of the cover plate c, which holds the lug b in the disc α , a second, identically shaped lug is used and firmly connected to the former, but in such a way that one faces to the right and the other to the left, and the valve levers become double and appropriately attached to the position of the lugs, this enables the machine to be reversed.
