Description

Luftkühlvorrichtung für Brennkraftmaschinen Die Erfindung betrifft eine Luftkühlvorrichtung für Brennkraftmaschinen mit durch Stange geführtem Hohlkolben, bei welcher der Hohlkolben am Kühllufteintrittsende des Zylinders gegen einen in seinen Hohlraum eintretenden Verdränger arbeitet, und besteht darin, daß der Umfang des Zylinders hinter der Kolbenlauffläche mit einer symmetrisch angeordneten Mehrzahl von Lufteintrittsöffnungen versehen ist, an die sich schraubenförmige Leitrinnen des Verdrängers anschließen. Hierdurch wird die bei Umkehr des Kolbens eingesaugte kalte Kühlluft sehr wirksam an die heißen Innenwandungen des Zylinders und besonders an die heiße hintere Kolbenfläche geleitet.Air cooling device for internal combustion engines The invention relates to an air cooling device for internal combustion engines with a hollow piston guided through a rod, in which the hollow piston at the cooling air inlet end of the cylinder against an in its cavity entering displacer works, and consists in that the circumference of the cylinder behind the piston running surface with a symmetrically arranged plurality is provided by air inlets to which helical guide channels of the displacer. This causes the sucked in when the piston is reversed cold cooling air very effective on the hot inner walls of the cylinder and especially directed to the hot rear piston surface.

In der Zeichnung zeigen Abb. i und 2 Schnitte durch den abgebrochenen Zylinder in verschiedenen Stellungen des Kolbens.In the drawing, Fig. I and 2 show sections through the broken off Cylinders in different positions of the piston.

In dem Zylinder z wird der Kolben 2 -hin und her geführt. Der Zylinder hat hinter der Kolbenlauffläche die Lufteintrittsöffnungen 3, die svmrnetrisch über den Umfang verteilt sind, und ist durch den nach innen gerichteten trichterförmigen Verdränger 4. abgeschlossen. Der Verdränger d. hat für die Kolbenstange 5 die Abdichtung C. Die äußere Trichterwandung ist mit schraubenförmigen Leitrinnen 7 versehen, die sich an die Lufteintrittsöffnungen 3 anschließen (Abb. 2).In the cylinder z, the piston 2 is guided back and forth. The cylinder has the air inlet openings 3 behind the piston running surface, which are symmetrically over are distributed around the circumference, and is funnel-shaped by the inwardly directed Displacer 4th completed. The displacer d. has the seal for the piston rod 5 C. The outer funnel wall is provided with helical guide channels 7 which connect to the air inlet openings 3 (Fig. 2).
