Description

Steuerung für Zweizylinder-Verbunddampfmaschinen Der Gegenstand der vorliegenden Erfindung betrifft die an sich bekannten Verbunddampfmaschinen mit um z8o ° versetzten Kurbeln, mit Wechselstromhochdruck- und Niederdruckgleichstromzylinder mit gemeinsamen Kolbenschieber und Hilfsauslässen für den Gleichstromzylinder. Und zwar sollen die zusätzlichen Auslaßventile für den Niederdrucl;zvlinder gleichachsig zu dem Kolbenschieber in der Weise angeordnet werden, daß sie von der Kolbenschieberstange durch Anstoßen geöffnet, durch Federkraft aber geschlossen werden.Control for two-cylinder compound steam engines The subject of the The present invention relates to the compound steam engines known per se Cranks offset by z8o °, with alternating current high pressure and low pressure direct current cylinders with common piston valve and auxiliary outlets for the direct current cylinder. and the additional outlet valves for the low pressure cylinder should be coaxial to the piston valve are arranged in such a way that they are removed from the piston valve rod opened by bumping, but closed by spring force.

In der Zeichnung ist ein Zylindersatz dargestellt. Der Dampf tritt bei a in den Schieberkasten b und in der gezeichneten Stellung durch Kanal c in den Hochdruckzylinder d unten ein, gesteuert durch den unteren Kolben des normalen Kolbenschiebers e. Der Abdampf des oberen Zylinderraumes geht durch den Kanal f und g zum oberen Niederdruckzylinder la, in welchem der Kolben i. die Schlitze lz für die untere Zylinderseite frei gab zum Austritt des Abdampfes dieser Seite. Gleichzeitig öffnet die Schieberstange das untere Kolbenventil z, welches einen Teil des Abdampfes durch Kanal m abführt. Das Kolbenventil ist federbelastet wie auch das obere Kolbenventil za, welches für die obere Zylinderseite dient.A cylinder set is shown in the drawing. The steam enters the valve body b at a and in the position shown through channel c into the high pressure cylinder d below, controlled by the lower piston of the normal piston valve e. The exhaust steam from the upper cylinder space goes through the channel f and g to the upper low-pressure cylinder la, in which the piston i. the slots lz for the lower side of the cylinder were free for the exhaust steam to escape from this side. At the same time, the slide rod opens the lower piston valve z, which discharges part of the exhaust steam through channel m. The piston valve is spring-loaded, as is the upper piston valve za, which is used for the upper cylinder side.

Der Vorteil dieser Steuerung liegt also darin, daß die Kolbenschieber normale Längen erhalten und daß die Kolbenventile, durch welche die Schieberstange lose hindurchgeht, nur kurze Öffnungshübe machen, welche durch die Schieberstange erzeugt werden, während diese Ventile durch Federn geschlossen werden, wodurch sie das Schiebergestänge nur für kurze Zeit belasten.The advantage of this control is that the piston slide obtained normal lengths and that the piston valves through which the slide rod loosely through it, only make short opening strokes, which through the slide rod are generated while these valves are closed by springs, causing them only load the slide linkage for a short time.
