Description

Kühlvorrichtung für Kolben von Brennkraftmaschinen. Es ist bekannt, die Kolben von Brennkraftinaschinen durch dagegengespritztes Öl zu kühlen. Bei der bekannten Einrichtung wird dieses Kühlöl durch feststehende. Rohre gegen den Kolbenboden gespritzt, so daß die Einrichtung bei rasch laufenden Motoren mit verhältnismäßig kleinen Kolben schwer angebracht werden kann.Cooling device for pistons of internal combustion engines. It is known, to cool the pistons of internal combustion engines with oil sprayed against them. In the known device, this cooling oil is fixed by. Pipes against the piston crown injected, so that the device with high-speed engines with relatively small flask is difficult to attach.

Gemäß der vorliegendenErfindung wird nun eine gedrängtere Anordnung dadurch erzielt, daß der Steg der Pleuelstange mit einem Schlitz versehen ist, durch welchen ein zwei Spritzdüsen tragendes Rohr hindurchgeführt wird, das mit der Öldruckpumpe in Verbindung steht. Infolgedessen kann die Öldruckleitung in der Mittelebene des Zylinders angeordnet werden. Das die Spritzdüsen tragende Rohrstück kann mit der Zuleitung einstellbar verbunden sein, um die Winkellage der Spritzdüsen gegenüber der Mittelachse des Zylinders einzustellen.In accordance with the present invention, there is now a more compact arrangement achieved in that the web of the connecting rod is provided with a slot through through which a pipe carrying two spray nozzles is passed, the one with the oil pressure pump communicates. As a result, the oil pressure line in the center plane of the Cylinder can be arranged. The pipe section carrying the spray nozzles can with the Supply line can be connected to the angular position of the spray nozzles opposite the central axis of the cylinder.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt.The drawing shows an exemplary embodiment of the subject matter of the invention shown schematically.

Abb. i zeigt einen Längsschnitt nach der Linie I-I der Abb. 2, Abb. 2 einen Längsschnitt nach der Linie II-II der Abb. i.Fig. I shows a longitudinal section along the line I-I of Fig. 2, Fig. 2 shows a longitudinal section along the line II-II of Fig. I.

Abb. 3 zeigt eine Einzelheit der Vorrichtung zur Einstellung der Pumpe.Fig. 3 shows a detail of the device for adjusting the pump.

In dem Block i ist der Zylinder angebracht, dessen topfförmiger Kolben z durch Pleuelstange 5 mit der Kurbelwelle 4 verbunden ist.In the block i the cylinder is attached, its cup-shaped piston z is connected to the crankshaft 4 by connecting rod 5.

Der Steg -der Pleuelstange 5 ist der ganzen Länge nach mit einem Schlitz 5' (Abb. 2) versehen und greift um ein Rohr 7 herum. Dieses Rohr ist mit einem von einer Ölpumpe gespeisten Zuleitungsrohr 8 verbunden und trägt zwei in der Mittelebene des Zylinders liegende Spritzdüsen 9, durch welche das unter Druck eintretende Öl gegen den Boden 2' des Kolbens :2 gespritzt wird, um diesen zu kühlen.The web of the connecting rod 5 has a slot along its entire length 5 '(Fig. 2) and engages around a tube 7. This pipe is with one of an oil pump fed supply pipe 8 connected and carries two in the central plane of the cylinder lying spray nozzles 9, through which the oil entering under pressure against the bottom 2 'of the piston: 2 is injected in order to cool it.

Um d!ie Düsen 9 möglichst genau in .die Zylinderebene einzustellen, ist das Rohr 7 einerseits mit einer im Kurbelkasten 13 bei i i gelagerten Muffe verbunden und stützt sich andererseits auf einen Dorn 12, der in den Kurbelkasten eingeschraubt ist. Die Muffe trägt fest einen Arm 14, dessen mit einem Schlitz 15 versehenes Ende an der Seitenwand des Kurbelkastens anliegt und durch eine Klemmschraube i o an diesem befestigt ist. Nach Lösung dieser Klemmschraube io kann das Rohr 7 um seine Achse gedreht werden.In order to adjust the nozzles 9 as precisely as possible in the cylinder plane, is the pipe 7 on the one hand with a socket mounted in the crankcase 13 at i i connected and is supported on the other hand on a mandrel 12, which in the crankcase is screwed in. The sleeve firmly carries an arm 14, the one with a slot 15 provided end rests against the side wall of the crankcase and by a clamping screw i o is attached to this. After loosening this clamping screw io, the pipe 7 be rotated around its axis.
