Description

Gekühlter Kolben für Verbrennungskraftmaschinen. Die Erfindung betrifft einen aus einem selbständigen Kolbenringträger und einem selbständigen Kolbenboden zusammengesetzten Kolben für 'Verbrenrnungsknaftmaschinen und hat die Kühlung eines derartigen Kolbens zum Gegenstand. Gegenüber bekannten Ausführungen mit Kühlmittelräumen im Kolbenringträger und Kolbenboden besteht die Erfindung darin, daß das Kühlmittel in bestimmter Weise durch den Kolben hindurchgeführt wird, derart, daß es in ungehindertem. Fluß zunächst durch den Kolbenringträger hindurchgeht, dann in den Kolbenboden übertritt und von diesem in eine mittlere Höhlung des Kolbenringträgers zurückkehrt, die an die Kühlmittelableitung angeschlossen ist. Esw ird dadurch eine wirksame Kühlung des gesamten Kolbens erzielt.Cooled piston for internal combustion engines. The invention relates to one made up of an independent piston ring carrier and an independent piston crown compound piston for internal combustion machines and has the cooling of a such piston to the subject. Compared to known designs with coolant spaces In the piston ring carrier and piston crown, the invention consists in that the coolant is passed in a certain way through the piston, so that it is in unimpeded. Flow first passes through the piston ring carrier, then overflows into the piston crown and from this returns into a central cavity of the piston ring carrier, which at the coolant discharge is connected. This provides effective cooling of the entire piston achieved.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel im Schnitt dargestellt. Der Kolben ist aus zwei vollständig selbständigen Teilen zusammengesetzt: dem Kolbenringträger a und dem Kolbenboden b. Ersterer besteht aus einem ringförmigen Hohlkörper, der auf das flanschartige Ende c' der Kolbenstange c aufgesetzt ist. Der Kolbenboden b ist gleichfalls hohl ausgebildet und ruht dicht passend auf dem Kolbenringträger a. Die Verbindung beider untereinander und mit der Kolbenstange c geschieht durch gemeinsame Schrauben d. Die Hohlräume e bzw. f des Kolbenringträgers a und des Kolbenbodens b dienen- als Kühlkammern. Die Zuleitung des Kühlmittels erfolgt in bekannter Weise durch die hohle Kolbenstange, der Übertritt in die Kühlkammer e durch einen Kanal g. - Die Kühlkammer e steht mit der Kühlkammer f wiederum durch einen Kanal 1a in Verbindung, so daß das Kühlmittel von dem Kolbenringträger a nach dem Kolbenboden b übertreten und von diesem durch einen Hohlraum i des Kolbenringträgers und das Innenrohr j der Kolbenstange abfließen kann.In the drawing, the invention is shown in an exemplary embodiment in section. The piston is composed of two completely independent parts: the piston ring carrier a and the piston crown b. The former consists of an annular hollow body which is placed on the flange-like end c 'of the piston rod c. The piston head b is also made hollow and rests in a tight fit on the piston ring carrier a. The connection between the two and with the piston rod c is done by common screws d. The cavities e and f of the piston ring carrier a and the piston crown b serve as cooling chambers. The coolant is fed in in a known manner through the hollow piston rod, and it enters the cooling chamber e through a channel g. - The cooling chamber e is in turn connected to the cooling chamber f through a channel 1a, so that the coolant can pass from the piston ring carrier a to the piston head b and can flow away from this through a cavity i of the piston ring carrier and the inner tube j of the piston rod.
