 und Welle dar, wobei der Kolben im inneren Totpunkt steht. Fig. 4 stellt einen Querschnitt durch einen Stern- oder Fächermotor dar. 



   Nach Fig. 1 und 2 ist   a   ein Kolben ; von seiner zylindrischen Wandung sind nur die Teile b   s@@hen gelassen,   die zur Aufnahme des   Geradführungsdruckes   dienen, während die weg-   ges@nnittenen   Teile durch die weiter innen liegenden   Seitenwände'c ersetzt sind. Diese Seiten-     wänL-e und nahe   dem Kolbenboden d durch einen Zwischenboden e verbunden. Auf diese Weise entsteht ein Kanal, der die Kühlluft dem Kolbenboden entlang führt. Am Zylinderende sind für den   Luftein-und   austritt zwei Abschlussstücke f und g angebracht, welche die Abdichtung 
 EMI2.1 
 aufrecht, die der Länge der Seitenwand c gleichkommt. 



   In Fig. 3 sind an den innen liegenden Wänden c des Kolbens a   Wandverlängerungen   h angebracht, wodurch die Abdichtung auf einer grösseren Hubstrecke gesichert wird. Fig. 3 lässt erkennen, dass durch die Kühleinrichtung weder die Baulänge des Zylinders eine   Verlängerung   erfährt, noch die Unterbringung der   Gegengewichte i behindeit wird.   



   Fig. 4 zeigt, dass selbst bei einer vielzylindrigen Sternmaschine von gedrängter Bauart die   Führungswände   c und h eine Länge erhalten, welche die Abdichtung während des ganzen Kolbenhubes gewährleistet.

 and shaft, with the piston at inner dead center. Fig. 4 shows a cross section through a star or fan motor.



   According to Figures 1 and 2, a is a piston; of its cylindrical wall only those parts are left which serve to absorb the straight line pressure, while the cut-away parts are replaced by the side walls located further inside. These side walls are connected by an intermediate base e near the piston head d. This creates a channel that guides the cooling air along the piston crown. At the end of the cylinder, two end pieces f and g are attached for the air inlet and outlet, which form the seal

 upright, equal to the length of the side wall c.



   In Fig. 3 wall extensions h are attached to the inner walls c of the piston a, whereby the seal is secured over a larger stroke distance. 3 shows that the cooling device neither extends the overall length of the cylinder nor does it hinder the accommodation of the counterweights i.



   Fig. 4 shows that even in a multi-cylinder star machine of compact design, the guide walls c and h are given a length which ensures the seal during the entire piston stroke.

PATENT. ANSPRÜCHE : Kolbenkilbieinrichtung mit Luftstrom für Verbrennungskraftmaschinen, dadurch gekennzeichnet, dass die unbelasteten Teile der Kolbenwandung ersetzt sind durch weiter innen liegende Wände mit einem sie verbindenden Zwischenboden nahe am Kolbenende, um mit der Zylinderwand und dem Kolbenboden einen Luftkanal zu bilden, dessen Mündungsquerschnitte durch feststehende, längs der hineingerückten Kolbenwandteile dichtende Abschlussstücke abgedeckt sind. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT. CLAIMS: Piston cylinder bending device with air flow for internal combustion engines, characterized in that the unloaded parts of the piston wall are replaced by walls lying further inside with an intermediate base connecting them close to the piston end in order to form an air duct with the cylinder wall and the piston base, the opening cross-sections of which are replaced by fixed, along the inserted piston wall parts sealing end pieces are covered. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
