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

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.
