Description

Kolbenabdichtung für Drehkolbenmaschinen. Es ist bei Drehkolbenmaschinen mit sicJielförmigem Arbeitsraum bekannt, in einer Trommel verschiebbare Kolben anzuordnen, welche zwecks Drehbeweglichkeit in den Trommelschlitzen seitliche, gelenkartig wirkende Kurvenflächen besitzen. Das Profil der Kolben von diesen Kurven$ächen bis zur Anlegefläche an die Gehäusewandung verlief bis jetzt unter allmählicher Verjüngung konkav-gekrümmt, was den Nachteil. hatte, daß sich die Kolben. an dem Drehgelenk mehr versehwenken konnten, als es unbeschadet der reibungslosen Einschiebbarkeit in die radialen Schlitze zulässig war, und daß, was noch scllädliaher war, in solcher scharf verschwenkten Lage cler Außenraum des Schlitzes, d. i. die Arbeitskammer mit dem darin herrschenden Druck des Treibmittels, mit dem Innenraum des Schlitzes in Verbindung kommen kannte und ein Gegendruck entstand, weicher die Reibungen erhöhte. Diese Nachteile werden erfindungsgemäß dadurch verhütet, daß von den Kurvenflächen nach außen .oder zum Gehäuse hin die Kolben nicht eine gekrümmte, sondern eine gerade Fläche beiderseitig besitzen und daß an den Übergangspunkten. der Kurvenflächen mit den geraden Flächen biegsame Lappen angeordnet sind, die durch den Druck des Treiboder Fördermittels von innen an die Wandung der Schlitze angedrückt werden.Piston seal for rotary piston machines. It is with rotary piston machines with a sicJiel-shaped working space known to arrange displaceable pistons in a drum, which, for the purpose of rotational mobility in the drum slots, act like a joint on the sides Have curved surfaces. The profile of the pistons from these curved surfaces to the contact surface on the housing wall has been concave-curved until now with a gradual taper, what the disadvantage. had that piston. more versehwenken on the swivel joint could, as it is without prejudice to the smooth insertion into the radial slots was admissible, and that what was still more subtle was swiveled sharply in such a way Location of the outer space of the slot, d. i. the working chamber with the ruling one in it Pressure of the propellant with which the interior of the slot knew to come into contact and a counter pressure was created, which increased the friction. These disadvantages will be according to the invention prevented that from the curved surfaces to the outside. or to Housing towards the piston is not a curved, but a straight surface on both sides own and that at the transition points. the curved surfaces with the straight surfaces flexible flaps are arranged, which by the pressure of the propellant or conveying means be pressed from the inside against the wall of the slots.

Die Zeichnungen veranschaulichen beispielsweise einige Ausführungsformen der Erfindung.For example, the drawings illustrate some embodiments the invention.

Abb. i zeigt einen Querschnitt der Maschine.Fig. I shows a cross section of the machine.

Abb. 2 und 3 zeigen weitere Ausführungsr formen der Kolben.Figs. 2 and 3 show other embodiments of the pistons.

Mit Bezug auf Abb. i ist in der Kolbentrommel 2 von zylindrischer Gestalt eine Anzahl von in Schlitzen oder Führungen 3 gelagerter Kolben 7 angeordnet. Die Trommel ist im Gehäuse q. exzentrisch, so daß die Arbeitskammer, die den Eimlaß 5 und den Auslaß 6 für das Treibmittel besitzt, sichelförmig ist. Die Kolben besitzen zwecks Drehbeweglichkeit in den Schlitzen 3 gelenkartig wirkende, seitliche Kurvenflächen 7b, und von diesen Stellen verlaufen dann die beiden seitlichen Flächen gerade und tangential.With reference to Fig. I, the piston barrel 2 is cylindrical Shape a number of stored in slots or guides 3 pistons 7 arranged. The drum is in the housing q. eccentric, so that the working chamber that has the inlet 5 and the outlet 6 for the propellant has, is sickle-shaped. Own the pistons for the purpose of rotational mobility in the slots 3, lateral curved surfaces that act like a joint 7b, and from these points the two lateral surfaces then run straight and tangential.

Die Trommel 2 ist im Innern mit einer Reihe von hanä.len 8 versehen, welche einen einheitlichen Gegendruck an der Innenseite der Kolben aufrechterhalten, und zwar mittels Rückschlagventile g.The inside of the drum 2 is provided with a number of handles 8, which maintain a uniform back pressure on the inside of the pistons, namely by means of check valves g.

An den Übergangspunkten der Kurvenflächen der Kolben mit den geraden Flächen derselben sind gemäß Abb.2 biegsame Lappen 13 befestigt, welche dicht 'gegen die Innenflächen der Schlitze 3 durch den im Innern der Trommel herrschenden Druck angep,reßt werden. Bei der Ausführwigsfarm gemäß Abb.3 bilden die biegsamen Platten i 3a ein Stück mit den Kolben 7.At the transition points of the curved surfaces of the piston with the straight Surfaces of the same are fixed according to Fig.2 flexible tabs 13, which tight 'against the inner surfaces of the slots 3 by the pressure prevailing inside the drum adapted to be tearing. At the export farm according to Fig. 3, the flexible plates form i 3a a piece with the piston 7.
