Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft umsteuerbare Kraftmaschinen mit umlaufenden, in der Kolbentrommel verschiebbaren Kolben, die durch den Dampfdruck unter Vermittlung von Ventilen abgedichtet werden.The invention relates to reversible power machines with rotating machines in the piston drum displaceable piston, which is caused by the steam pressure through the intermediary of valves be sealed.

Das Neue besteht darin, daß die Kolben nicht nur gegen die Zylinderwandung, sondern auch in ihren Führungen abgedichtet werden.The novelty is that the piston not only against the cylinder wall, but also be sealed in their guides.

ίο In der Zeichnung ist die Erfindung in Fig. ι teils im Längsschnitt, teils in Ansicht und in Fig. 2 im Querschnitt dargestellt. Fig. 3 zeigt eine Einzelheit.ίο In the drawing, the invention is in Fig. Ι shown partly in longitudinal section, partly in view and in Fig. 2 in cross section. Fig. 3 shows a detail.

Die Kolben α sind in bekannter Weise in der mit. der Welle fest verbundenen Trommel b gelagert, welche sich in einem mit Kanälen für die Zu- und Ableitung des Treibmittels versehenen Gehäuse c dreht, das durch Widerlager d hier beispielsweise in zwei Arbeitsräume I und II geteilt ist. Die Kolben a werden durch die Blattfedern e an die Gehäusewand gedrückt und ohne weitere Hilfsorgane durch entsprechendes Abrunden der Widerlager d selbsttätig gesteuert.The piston α are in a known manner in the with. the shaft firmly connected drum b , which rotates in a housing c provided with channels for the supply and discharge of the propellant, which is divided by abutment d here, for example, into two working spaces I and II. The pistons a are pressed against the housing wall by the leaf springs e and are automatically controlled without further auxiliary elements by appropriate rounding of the abutments d.

Die Kolben α sind aus zwei Teilen hergestellt und mit einer Bohrung g (Fig. 1) versehen, welche sich auf die ganze Höhe des Kolbens erstreckt und in den Ventilraum desselben mündet.The pistons α are made of two parts and provided with a bore g (Fig. 1) which extends over the entire height of the piston and opens into the valve chamber of the same.

In dem oberen Teil der Kolben α sind die Ventile f angeordnet, welche, wie die Kolben, aus zwei Teilen bestehen und durch Federn fx auf ihren kegelförmigen Sitz gepreßt werden (s. Fig. 3).In the upper part of the piston α , the valves f are arranged, which, like the pistons, consist of two parts and are pressed onto their conical seat by springs f x (see FIG. 3).

Strömt nun das Treibmittel, z. B. Dampf, in die Arbeitsräume, so wird das Ventil des von Dampf beaufschlagten Kolbens in diesen hineingedrückt und dadurch auf der Einströmseite geöffnet, so daß der Dampf durch die Bohrung g unter den Kolben in den zur Aufnähme der Blattfedern β dienenden Raum tritt. In diesem herrscht jetzt gleicher Druck, wie im Arbeitsraum, so daß hierdurch die Anpressung des Kolbens an die Gehäusewand erhöht wird. Zugleich drückt der Dampf auch die beiden Teile des Kolbens auseinander, wodurch dieselben an die Führung in der Kolbentrommel angedrückt werden. Now flows the propellant, z. B. steam, in the working spaces, the valve of the piston acted upon by steam is pressed into this and thereby opened on the inflow side, so that the steam passes through the bore g under the piston in the space serving to accommodate the leaf springs β. In this there is now the same pressure as in the working space, so that this increases the pressure of the piston against the housing wall. At the same time, the steam also pushes the two parts of the piston apart, as a result of which they are pressed against the guide in the piston drum.

Durch diese Einrichtung wird also eine vollkommene und dauernde Abdichtung herbeigeführt. A complete and permanent seal is thus brought about by this device.

Beim Vorbeigang des Kolbens an der Austrittsöffnung pufft der Dampf durch die Bohrung g mit demjenigen des Arbeitsraums aus und das Ventil wird Unter gleichzeitigem Zurücktreten des Kolbens durch die innenliegende Feder geschlossen. Nach dem Übergleiten des Vorsprunges d wiederholt sich der Vorgang in der eben beschriebenen Weise.When the piston passes the outlet opening, the steam puffs out through the bore g with that of the working chamber and the valve is closed by the internal spring while the piston is simultaneously retreating. After the projection d has slipped over, the process is repeated in the manner just described.
