Description

Drehkolbenmaschine mit in der Kolbenscheibe axial verschiebbaren Kolben und schräg dazu gestelltem Gehäuse Es sind Drehkolbenmaschinen bekannt, bei. denen die Achse eine im Querschnitt doppeltrapezförmige Kolbenscheibe trägt, die sich in einem schräg dazu gestellten Gehäusie dreht und von axial verschiebbaren, trap,ezförmi,-gen Kolben durchdrungen wird.Rotary piston machine with axially displaceable pistons in the piston disk and inclined housing there are rotary piston machines known in. those the axis carries a piston disk with a double trapezoidal cross section, which is rotates in an inclined housing and is axially displaceable, trap, ezförmi, -gen Piston is penetrated.

Die Leistungsfähigkeit dieser Maschinen ist stark beeinträchtigt durch die Schleuderkraft der querbeweglichen Koben, welche erhebliche Reibung an der Zy@inderwand und dadurch hohen. Kraftverbrauch, Erwärmung und Verschleiß verursachen.The performance of these machines is severely affected by the centrifugal force of the transversely movable piston, which creates considerable friction on the cylinder wall and therefore high. Cause power consumption, heating and wear.

Um diesen Mangel zu beheben, sind bei der neuen Maschine die querbeweglichen Kolbe. am äußeren Ende an einem Ring befestigt.In order to remedy this deficiency, the new machines are transversely movable Kolbe. attached to a ring at the outer end.

Ein. Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt; es zeigen die Maschine Abb. i im senkrechten Schnitt durch die Wellenachse, Abb. 2 im Querschnitt.A. Exemplary embodiment of the subject matter of the invention is shown in the drawing shown; it shows the machine Fig. i in a vertical section through the shaft axis, Fig. 2 in cross section.

Die Achse a trägt zwei halbkugelförmige Körperb und die im Querschnitt doppeltrapezfönnige Kolbenscheibed, die sternförmige Schlitze besitzt, in denen die trapezförmigen Kolben/ gleiten. Die äußeren Enden dieser Kolben/ sind ,mit einem innen kugelig und außen zylindrisch ausgebildeten Ring g durch Schweißung, Lötung oder sonstwie fest verbunden.The axis a carries two hemispherical bodies b and the one in cross section double trapezoidal piston disk with star-shaped slots in which the trapezoidal pistons / slide. The outer ends of these pistons / are, with a inside spherical and outside cylindrical ring g by welding, soldering or otherwise firmly connected.

Das Gehäuseh ist schräg zur Achsea gestellt, und die Deckel il und P sind kegelig derart ausgebildet, daß beiderseits der Scheibe d Räume entstehen, deren Inhalt in der Drehrichtung von Null bis zu einem Höchstwert wächst und dann wieder abnimmt. h, h sind Saugstutzen, C, L Druckstutzen für die Förderflüssigkeit.The housing is inclined to the axisea, and the covers il and P are conical in such a way that spaces are created on both sides of the disk d, the content of which increases in the direction of rotation from zero to a maximum value and then decreases again. h, h are suction nozzles, C, L pressure nozzles for the fluid to be conveyed.

Der Ring g nimmt die Schleuderkraftwirkungen aller Kolben/ auf, gleitet aber im Gehäuse h ohne einseiige Belastung.The ring g absorbs the centrifugal force effects of all pistons / slides but in the case h without unilateral loading.

Da die Kolben/ mit dem Ring g fest verbunden sind, kann kein Undichtgkeitsverlust mehr an dieser Stelle auftreten, und die Abdichtung ist auch bei. kleinster Drehzahl gesichert.Since the pistons / are firmly connected to the ring g, there can be no leakage loss more occur at this point, and the seal is also at. lowest speed secured.
