Description
Gestalt und Abdichtung des Kolbens für Drehkolbenmaschinen mit Drehwiderlager. Die Erfindung betrifft die Gestalt und Abdichtung des Kolbens für Drehkolben.-maschinen mit Drehwiderlager, die aus einem zylindrischen, in das Maschinengehäuse eingeschliffenen Körper bestehen und zum Steuern des Treibmittelein- und -auslasses dienen.Shape and sealing of the piston for rotary piston machines with rotary abutments. The invention relates to the shape and sealing of the piston for rotary piston machines with rotary abutment, which consists of a cylindrical, ground into the machine housing Body exist and serve to control the propellant inlet and outlet.
Das Neue besteht darin, daß der bei geringer Breite rechteckige, sonst mit Bezug auf seine zur Welle senkrechte Mittelebene doppeltrapezförmige Gestalt habende Kolben Dichtungsleisten hat, die aus einem Stück bestehen, in sich federn' und der Form des Kolbens angepaßt sind: Die Seitenteile der Dichtungsringe legen sich beim Durchgang des Kolbens durch die Aushöhlung des Widerlagers an Paßfiächen der Seitenwände des letzteren,. so daß die Ringe schon allein durch die seitliche Führung in unveränderter Lage bleiben und nach- Durchgang wieder genau auf die Innenwand des Zylinders übergehen. Gegenüber anderen Kolbenabdichtungsarten zeichnet sich die vorliegende durch ihre Einfachheit und sichere Wirkungsweise aus Die Zeichnung zeigt ein Ausführungsbeispiel, und zwar in Abb. i einen Mittelschnitt durch das Widerlager, senkrecht zur Welle mit dem Kolben in Seitenansicht und Abb. a in achsialem Mittelschnitt durch das Widerlager und einen Kolbenring mit dem Kolben und .dem Zylinder. Das Widerlager besitzt die erwähnten Paßflächen p und einen Steuerkanal k für den Betriebsstoff. Im Maschinen-- gehäuse dreht sich der Kolben n mit seiner Kolbenscheibe m. Der dein Steuerkanal k entsprechende Einlaß im .Zylinder ist mit i bezeichnet.The novelty is that if the width is small, it is rectangular, otherwise with reference to its central plane perpendicular to the shaft, double trapezoidal shape having pistons has sealing strips that consist of one piece, spring in themselves' and are adapted to the shape of the piston: Place the side parts of the sealing rings when the piston passes through the recess of the abutment on mating surfaces the side walls of the latter ,. so that the rings just by the side Guide remain in the same position and after-pass again exactly on the inner wall of the cylinder. Compared to other types of piston seals the present one from the drawing due to its simplicity and safe mode of operation shows an embodiment, namely in Fig. i a central section through the Abutment, perpendicular to the shaft with the piston in side view and Fig. A in axial Center section through the abutment and a piston ring with the piston and .dem Cylinder. The abutment has the aforementioned mating surfaces p and a control channel k for the fuel. In the machine housing, the piston n rotates with its Piston disk m. The inlet in the cylinder corresponding to your control channel k is with i denotes.
