Description

Kolben für Brennkraftmaschinen mit zwischen seinem durch Verschraubung verbundenen Boden- und Lagerzapfenteil geführtem federndem Laufmantel Kolben, für Brennkraftmaschinen mit federndem Laufmantel, der zwischen dem durch Verschraubung verbundenen Boden- und Lagerzapfenteil des Kolbens geführt ist, sind bekannt. Bei diesen Kolben reicht der federnde Laufmantel nur über einen Teil des Kolbens, und zwar bleibt der die Kolbenringe aufnehmende Teil mit dem Kolbenboden aus einem Stück hergestellt.Pistons for internal combustion engines with between his by screwing connected bottom and journal part guided resilient barrel jacket piston, for Internal combustion engines with a resilient barrel jacket, which is screwed between the connected bottom and journal part of the piston is known. at this piston extends the resilient barrel jacket only over part of the piston, and although the part receiving the piston rings remains in one piece with the piston crown manufactured.

Nach der. Erfindung erstreckt sich der federnde Laufmantel zur Abdichtung des ganzen Kolbens vom oberen bis zum unteren Kolbenrande, nimmt auch die Kolbenringe auf und ist mit seinen beiden Endflächen sowie mit nach innen gerichteten Vorsprüngen zwischen, den. verschraubten Kolbenteilen frei drehbar geführt. Durch diese Ausbildung soll eine gute Anpassung des Kolbens an den Zylinderquerschnitt und damit eine stets gute Abdichtung, besonders bei schnellaufenden Maschinen, erreicht werden.After. Invention extends the resilient barrel jacket for sealing of the entire piston from the upper to the lower edge of the piston, also takes the piston rings on and is with its two end faces as well as with inwardly directed projections between. screwed piston parts freely rotatable. Through this training should a good adaptation of the piston to the cylinder cross-section and thus always good sealing, especially with high-speed machines, can be achieved.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Abb. i ist ein Längsschnitt und Abb. 2 ein Querschnitt durch den Kolben.Fig. I is a longitudinal section and Fig. 2 is a cross section through the piston.

Der Kolben besteht aus dem Bodenteil a, dem das Bolzenlager d enthaltenden Unterteil b, dem federnden, drehbaren Laufmantel c und den beiden Abdichtungsringen, g. . Der Bodenteil a und der Unterteil b sind durch Verschraubung verbunden. Wenn der Bodenteil a und Unterteil b aufeinandergeschraubt sind, entsteht eine Führungsnut III in der Mitte des Kolbens. In dem Laufmantel c, der auch die Kolbenringe g enthält,. sind zur Gewichts- und Flächenersparnis vier Schlitze f angebracht. Innen an dem Laufmantel c sind drei Vorsprünge e vorhanden, mit denen er drehbar zwischen den beiden Kolbenteilen in der Nut III geführt ist. Außerdem ist der Laufmantel mit seinen beiden Stirnflächen zwischen den Kolbenteilen geführt.The piston consists of the bottom part a, the lower part b containing the pin bearing d, the resilient, rotatable barrel jacket c and the two sealing rings, g. . The bottom part a and the lower part b are connected by screwing. When the bottom part a and lower part b are screwed together, a guide groove III is created in the center of the piston. In the barrel jacket c, which also contains the piston rings g. four slots f are provided to save weight and space. On the inside of the barrel jacket c there are three projections e with which it is rotatably guided between the two piston parts in the groove III. In addition, the barrel jacket is guided with its two end faces between the piston parts.
