Description

Kolben-Seitendichtung für Maschinen mit umlaufendem Kolben und in den Seitenflächen des Kolbens und des feststehenden Deckelringes angeordneten Dichtungsringen. Bei sämtlichen Maschinen mit umlaufendem Kolben ist auf gute Eckenabdichtung an den Stirnseiten der Maschine besonderer Wert zu legen, da hiervon die Wirtschaftlichkeit der Maschine mit abhängt.Piston side seal for machines with rotating pistons and in the side surfaces of the piston and the fixed cover ring arranged sealing rings. All machines with rotating pistons require good corner sealing to attach particular importance to the front sides of the machine, because of this the economic efficiency depends on the machine.

Für die Abdichtung des Arbeitsraumes bei solchen Maschinen werden Dichtringe angeordnet, die ein Durchtreten des Arbeitsmittels nach außen oder nach der Welle zu verhindern. Aus Herstellungsgründen verbleibt aber hierbei ein Ringspalt zwischen den zu dichtenden Flächen, der ein Überströmen vom Druckraum zum Saugraum in der Umfangsrichtung zuläßt. Diesen Ringspalt nach Möglichkeit zu verringern, ist Gegenstand der vorliegenden Erfindung.For sealing the work area in such machines Sealing rings arranged that a penetration of the working medium to the outside or after to prevent the wave. For manufacturing reasons, however, an annular gap remains between the surfaces to be sealed, the overflow from the pressure chamber to the suction chamber in the circumferential direction. This annular gap if possible to reduce is the subject of the present invention.

In der Zeichnung ist in Abb. r eine beispielsweise gewählte Maschine im Querschnitt, in Abb. 2 ein Längsschnitt durch den Arbeitsraum dargestellt.In the drawing, Fig. R shows a machine that has been selected as an example in cross section, in Fig. 2 a longitudinal section through the working space.

Auf der Welle a sitzt der mit dem Exzenter b fest und konzentrisch verbundene Kolben c, dieser schließt mit dem feststehenden, konzentrisch zur Welle a angeordneten Deckelring g den sichelförmigen Arbeitsraum f ein. Auf dem Exzenter b ist das Widerlager d drehbeweglich angeordnet, das vermittels der Nuß e durch den feststehenden Ring g hindurchgeführt ist und den Arbeitsraum f in Saug- und Druckraum unterteilt. An den ebenen Stirnflächen des Kolbens c und des Deckelringes g sind Dichtringe i bzw. k angeordnet, die den Arbeitsraum nach dem Gehäuse bzw. der Welle hin abdichten. Die Ausbildung der Dichtringe spielt im vorliegenden Fall keine Rolle. In Abb. 2 sind sie in einen besonderen Dichtring und Druckring unterteilt, die Ausführung kann jedoch beliebig sein.The piston c, which is firmly and concentrically connected to the eccentric b, is seated on the shaft a; it encloses the sickle-shaped working space f with the stationary cover ring g, which is arranged concentrically to the shaft a. On the eccentric b, the abutment d is rotatably arranged, which is passed through the stationary ring g by means of the nut e and divides the working space f into suction and pressure space. Sealing rings i and k are arranged on the flat end faces of the piston c and the cover ring g, which seal the working space from the housing or the shaft. The design of the sealing rings does not play a role in the present case. In Fig. 2 they are divided into a special sealing ring and pressure ring, but the design can be any.

Die erforderliche Verringerung des Ringspaltes, wie sie nach den einleitenden Ausführungen wünschenswert ist, erfolgt dadurch, daß sowohl die scharfen Ecken des Kolbens als auch des Deckelringes abgeschrägt und die bezüglichen Winkel entsprechend ausgefüllt sind. Veranschaulicht ist dies in Abb. 2, dort sind die Abschrägungen des Kolbens mit 1, die des Deckelringes mit m bezeichnet. Die Ausfüllung der- Winkel erfolgt durch die Abschrägungen n bzw. o. Es kann aber auch die Anordnung so getroffen «.erden, daß die Abschrägungen nur an einer Seite, z. B. nur an der Außenseite, vorgesehen werden.The required reduction of the annular gap, as it is after the introductory Executions is desirable, is done in that both the sharp corners of the Piston and cover ring beveled and the relevant angle accordingly are filled out. This is illustrated in Fig. 2, there are the bevels of the piston with 1, that of the cover ring with m. The filling of the- angles takes place through the bevels n or o. However, the arrangement can also be made in this way «.Erden that the bevels are only on one side, e.g. B. only on the outside, are provided.

Bei dieser Ausführung verbleiben dann; nur noch, wie in Abb. 2 dargestellt, die unvermeidlichen Spalte p bzw. q, die so klein als praktisch möglich gehalten werden können.With this execution then remain; only the unavoidable gaps p and q , as shown in Fig. 2, which can be kept as small as practically possible.
