Description

Anordnung der Ein- und Auslaßöffnungen bei Drehkolbenmaschinen mit- veränderlicher Leistung durch Änderung der Exzentrizität. Bei Drehkolbenmaschinen, bei denen die Leistung durch Verstellen der Entfernung der Achsen von Kolbentrommel und Zylinder verändert werden kann, wurden bisher Ein- und Auslaß des Treib- oder Fördermittels quer zur Verstellrichtung angeordnet. Die vorliegende Erfindung beruht darauf, daß sowohl der Ein- als auch der Auslaß nahe der Stelle der kleinsten Kolbenfläche angeordnet ist, und zwar derart, daß diese angenähert tangential zur Laufrichtung der Kolben münden. Der tangenti;ale Anschluß bei unveränderlichen Drehkolbenmaschinen ist zwar bekannt, nicht dagegen bei solchen mit veränderlicher Leistung, und gerade hierbei bietet diese Anordnung gegenüber dei Queranordnung wesentliche Vorteile, da bei diesen Maschinen bei größeren Verstellungen recht beträchtliche Geschwindigkeiten auftreten können, wodurch ein glatter Durchfluß mit möglichst geringen Richtungswechseln erforderlich ist, und auch durch die Verstellung keine Änderung in den Durchflußrichtungen und den Widerständen eintreten darf.Arrangement of the inlet and outlet openings in rotary piston machines with variable performance by changing the eccentricity. For rotary piston machines, where the power is achieved by adjusting the distance between the axes of the piston drum and cylinder can be changed, so far were inlet and outlet of the propellant or Conveyor arranged transversely to the adjustment direction. The present invention is based ensure that both the inlet and the outlet are close to the location of the smallest piston area is arranged, in such a way that it is approximately tangential to the direction of travel the flask open. The tangent connection in unchangeable rotary piston machines is known, but not in those with variable performance, and straight this arrangement offers significant advantages over the transverse arrangement, because with these machines quite considerable speeds with larger adjustments can occur, resulting in a smooth flow with as few changes in direction as possible is required, and no change in the flow directions due to the adjustment and resistance may occur.

In der Zeichnung ist die Erfindung beispielsweise in einer Ausführungsform dargestellt. Die Abb. i und a zeigen eine Maschine mit dieser Anordnung im Längs- und Querschnitt, und zwar bei großem Achsabstand E, während Abb. 3 die Maschine bei kleinem Achsabstand wiedergibt.In the drawing, the invention is for example in one embodiment shown. Fig.i and a show a machine with this arrangement in the longitudinal and cross-section, with a large center distance E, while Fig. 3 shows the machine reproduces with a small center distance.

a ist die Kolbentrommel, b sind die Kolben, c ist der Zylinder, d ist ein Lagergehäuse für Kolbentrommel und Zylinder, e ist eine Spindel, durch die die Verstellung des Zylinders bewirkt wird. Das Trieb- oder Fördermittel tritt bei C oder D ohne wesentlichen Richtungswechsel in den Zylinder c, in dem die gewünschte Wirkung durch die verschieden weit aus der Kolbentrommel a herausstehenden Kolben b erzielt wird. Der Ein- und Auslaß kann wie gezeichnet, in die beiden Führungszapfen des Zylinders oder in einen entsprechend ausgebildeten, größeren, gemeinschaftlichen Zapfen gelegt werden. Ex kann auch getrennt von diesen angeordnet sein. Durch die Anordnung der Zu- und Abführung in der Verschieberichtung des Zylinders läßt sich auch eine gute Abdichtung der Anschlüsse erzielen, zu denen der Zylinder ebenfalls verschoben werden muß.a is the piston drum, b are the pistons, c is the cylinder, d is a bearing housing for the piston drum and cylinder, e is a spindle that adjusts the cylinder. The drive or conveying means enters the cylinder c at C or D without any significant change of direction, in which the desired effect is achieved by the piston b protruding differently from the piston drum a. The inlet and outlet can, as shown, be placed in the two guide pins of the cylinder or in a correspondingly designed, larger, common pin. Ex can also be arranged separately from these. By arranging the supply and discharge in the direction of displacement of the cylinder, it is also possible to achieve good sealing of the connections to which the cylinder must also be displaced.
