Description

Die Erfindung betrifft eine Gehäuseabdichtung für eine wassergekühlte Zweitakt-Brennkraftmaschine mit einem den ungeteilten Zylinder umgebenden Kühlwassermantel, der nach oben zu durch einen mit einem Durchbruch für den Durchtritt der Zündkerze versehenen Deckel abgeschlossen ist.The invention relates to a housing seal for a water-cooled Two-stroke internal combustion engine with a cooling water jacket surrounding the undivided cylinder, the up to through one with a breakthrough for the spark plug to pass through provided lid is complete.

Die gegossenen Gehäuse wassergekühlter Maschinen bestehen in der Regel aus einem oben offenen, die Lauffläche enthaltenden Zylinder, der durch einen Zylinderdeckel abgeschlossen wird. Die Innenseite des Zylinderdeckels bildet dabei einen Teil der Zylinderbegrenzung. Für luftgekühlte Zweitakt-Maschinen sind auch ungeteilte Zylinder bekannt. Es entfallen dabei die Dichtungsprobleme des zusammengesetzten Zylinders.The cast housings of water-cooled machines are usually made from an open-topped cylinder containing the running surface, which is passed through a cylinder cover is completed. The inside of the cylinder cover forms part of the Cylinder limitation. Undivided cylinders are also available for air-cooled two-stroke machines known. The sealing problems of the assembled cylinder are eliminated.

Nach der Erfindung wird dieser Vorteil für eine wassergekühlte Maschine dadurch erreicht, daß die Abdichtung des Deckels des Kühlwassermantels gegen den ungeteilten Zylinder in an sich bekannter Weise über Dichtflächen derart erfolgt, daß einer die Zündkerzengewindebohrung zylindermantelförmig umgebenden Dichtfläche am Zylinder eine entsprechend gestaltete Dichtfläche am Durchbruch des Deckels zugeordnet und zwischen den Dichtflächen eine ringförmige Dichtung vorgesehen ist, wobei die Durchmesser der Dichtflächen so bemessen sind, daß die ringförmige Dichtung nur radial gepreßt ist.According to the invention, this advantage becomes available for a water-cooled machine achieved in that the sealing of the cover of the cooling water jacket against the undivided cylinder takes place in a manner known per se over sealing surfaces in such a way that that a sealing surface surrounding the spark plug threaded bore in the shape of a cylinder jacket a correspondingly designed sealing surface is assigned to the opening of the cover on the cylinder and an annular seal is provided between the sealing surfaces, the Diameter of the sealing surfaces are dimensioned so that the annular seal only is pressed radially.

An Hand der Abbildung soll die Erfindung nachfolgend an einem Ausführungsbeispiel erläutert werden.On the basis of the figure, the invention is intended to be based on an exemplary embodiment explained.

Die Zeichnung stellt einen Schnitt durch den oberen Teil des äußeren Zylinders einer Zylinderreihe einer Zweitakt-Maschine mit V-förmiger Zylinderanordnung dar. Das gegossene Maschinengehäuse weist ungeteilte Zylinder 1 und einen Kühlwassermantel2 auf. Der Kühlwasserraum ist durch einen Deckel 3 abgeschlossen, der mit einem Dichtflansch 4 auf einen entsprechenden Dichtflansch 5 des Kühlwassermantels 2 aufgesetzt und mittels Schrauben 6, 7 festgezogen ist. Zwischen der ringförmigen Dichtfläche des oberen, eine kreisförmige Öffnung bildenden Randes 8 des Deckels 3 und der die Zündkerzengewindebohrung (des Zylinders 1) zylindermantelförmig umgebenden Dichtfläche ist dabei eine ringförmige Dichtung 9 eingepreßt. Die Dichtung 9 hat in Richtung der Zylinderachse Spiel und ist nur in radialer Richtung gepreßt. Es brauchen in der Fertigung daher nur die Durchmesser der beiden zylindrischen Dichtflächen genau eingehalten zu werden, nicht dagegen das Höhenmaß des Deckels 3 und die entsprechenden Maße des Zylinders und des Dichtflansches 5 des Kühlwassermantels 2.The drawing represents a section through the upper part of the outer Cylinder of a cylinder bank of a two-stroke engine with a V-shaped cylinder arrangement The cast machine housing has undivided cylinders 1 and a cooling water jacket 2 on. The cooling water space is closed by a cover 3 with a sealing flange 4 placed on a corresponding sealing flange 5 of the cooling water jacket 2 and is tightened by means of screws 6, 7. Between the annular sealing surface of the upper, a circular opening forming edge 8 of the cover 3 and the spark plug threaded hole (of the cylinder 1) in the shape of a cylinder jacket surrounding the sealing surface is an annular Seal 9 pressed in. The seal 9 has play and play in the direction of the cylinder axis is only pressed in the radial direction. Therefore, only the Diameter of the two cylindrical sealing surfaces to be adhered to exactly, not however, the height of the cover 3 and the corresponding dimensions of the cylinder and of the sealing flange 5 of the cooling water jacket 2.
