Description

Kreiskolbenmaschine Die Erfindung geht aus von einer Kreiskolbenmaschine mit einem Gehäuse, bestehend aus einem feststehenden Mantel und Seitenteilen, wobei der Mantel eine innere Mantelfläche aufweist und zusammen mit den Seitenteilen einen Innenraum begrenzt, welcher einen Kolben mit Radialdichtungen aufweist.Rotary piston machine The invention is based on a rotary piston machine with a housing consisting of a fixed shell and side parts, wherein the jacket has an inner jacket surface and, together with the side parts, a Limited interior space, which has a piston with radial seals.

Es ist bekannt, daß derartige Dichtungen in hohem Maße dem Verschluß unterliegen und daß die teilweise Zerlegung der Maschine zum Zweck der Inspektion oder der Auswechslung der Radialdichtungen großen Arbeitsaufwand und längere Betriebsunterbrechungen verursachen.It is known that such seals to a large extent the closure and that the partial disassembly of the machine for the purpose of inspection or the replacement of the radial seals requires a lot of work and lengthy business interruptions cause.

Zur Verminderung dieser Schwierigkeiten hat man Verschlußstopfen in den Seitenteilen angeordnet, durch deren Sitzbohrung die Radialdichtungen zugänglich und in axialer Richtung aus- und einbaubar gemacht werden. Die Nachteile einer solchen Anordnung bestehen darin, daß für den Aus- und Einbau der Radialdichtungen seitlicher Raum beansprucht wird, wodurch besonders bei Mehrfachmaschinen eine bedeutende Vergrößerung der Baulänge notwendig wird, und daß die Radialdichtungen erst in ihrer ganzen Länge sichtbar sind, nachdem sie ganz aus ihrer Nut herausgezogen werden. Letzteres ist aber wegen der in den Nuten eingebetteten Anpreßfedern mit Schwierigkeiten verbunden.To reduce these difficulties, sealing plugs in the side parts arranged, through the seat bore, the radial seals accessible and can be removed and installed in the axial direction. The disadvantages of such Arrangement is that for the removal and installation of the radial seals laterally Space is required, which is a significant increase, especially in the case of multiple machines the overall length is necessary, and that the radial seals only in their entire length are visible after they have been pulled completely out of their groove. The latter is but associated with difficulties because of the compression springs embedded in the grooves.

Die dieser Erfindung zugrunde liegende Aufgabe besteht in der Schaffung einer Anordnung, bei der die genannten Schwierigkeiten nicht auftreten.The object underlying this invention is to provide an arrangement in which the difficulties mentioned do not arise.

Die Aufgabe wurde dadurch gelöst, daß der Mantel ein sich über die ganze Breite erstreckendes Einsatzstück aufweist, das einen Teil der inneren Mantelfläche bildet und herausnehmbar im Mantel befestigt ist.The object was achieved in that the coat is on the has the entire width extending insert piece, which is part of the inner circumferential surface forms and is removably attached in the jacket.

Besonders vorteilhaft ist eine Anordnung, bei der das Einsatzstück die Einlaßöffnung aufweist, da die in diesem Bereich am Mantel und an den Radialdichtungen angreifenden Kräfte am kleinsten sind.An arrangement in which the insert has the inlet opening, as in this area on the jacket and on the radial seals attacking forces are smallest.

Um einen stoßfreien Übergang der Radialdichtung über die Stoßfugen zwischen dem Mantel und dem Einsatzstück zu gewährleisten, wird vorgeschlagen, das Einsatzstück an seinem der inneren Mantelfläche zugewandten Ende mit* einer einer Kerbverzahnung ähnlichen Passung und Abdichtung in den Mantel einzusetzen.To a smooth transition of the radial seal over the butt joints between the shell and the insert to ensure it is proposed a use of the insert piece at its inner circumferential surface facing the end with * a serration-like fit and sealing in the casing.

In den Zeichnungen ist eine Ausführungsform der Maschine beispielsweise dargestellt.In the drawings, one embodiment of the machine is for example shown.

A b b. 1 zeigt einen Teil des Querschnitts durch eine Kreiskolbenmaschine; A b b. 2 zeigt einen Schnitt nach der Linie A -A in Abb.1; A b b. 3 zeigt eine Einzelheit der A b b. 1 in einem gegenüber der A b b. 1 größeren Maßstab; A b b. 4 zeigt einen Schnitt nach der Linie B-B in Ab b.3.A b b. 1 shows part of the cross section through a rotary piston machine; A b b. Figure 2 shows a section along the line A -A in Figure 1; A b b. 3 shows a detail of A b b. 1 in one across from A b b. 1 larger scale; A b b. 4 shows a section along the line BB in Ab b.3.

Damit die Radialdichtungen 1 des Kolbens 2 ohne Behinderung ein- und ausgebaut werden können, ist im Mantel 3 ein über seine ganze Breite verlaufendes Einsatzstück 4 vorgesehen, durch dessen Einsatzöffnung die Radialdichtungen 1 des Kolbens 2 ein-und ausgebaut werden können. Das Einsatzstück 4 ist im Bereich der Einlaßöffnung 5 des Mantels 3 angeordnet, derart, daß es selbst die Einlaßöffnung 5 enthält. Das Einsatzstück 4 ist an seinem dem Inneren der Kreiskolbenmaschine zugewandten Ende mit einer einer Kerbverzahnung 6 ähnlichen Passung und Abdichtung in den Mantel 3 eingesetzt. 7 sind die Schrauben zur Befestigung des Einsatzstückes 4, 8 sind Schrauben zur Befestigung einer Ansaugleitung.So that the radial seals 1 of the piston 2 can be installed and removed without hindrance, an insert 4 extending over its entire width is provided in the jacket 3, through the insert opening of which the radial seals 1 of the piston 2 can be installed and removed. The insert 4 is arranged in the region of the inlet opening 5 of the casing 3 in such a way that it contains the inlet opening 5 itself. At its end facing the interior of the rotary piston machine, the insert 4 is inserted into the jacket 3 with a fit and seal similar to serrations 6. 7 are the screws for fastening the insert 4, 8 are screws for fastening a suction line.
