  Air-cooled piston for two-stroke engines operated with liquid fuel.
 EMI1.1
 of the working piston and the piston pin of internal combustion engines. It is known that the crankcase a! s Use a charge pump for the combustion mixture and use the weakly compressed mixture on its way from the crankcase to the working cylinder to cool the piston.



   For the machines for which the subject of the invention is intended, only the
 EMI1.2
 
In order to force the air on its way from the Kurhel housing to the working cylinder to effectively cool the inner piston walls and the piston pin, the piston pi no septum is built into the piston, which sits below the air outlet channel and almost reaches the connecting rod head, so that the air is forced to travel a long way in the hollow piston chamber.



   It can be seen from the drawing that the piston 1 with the air outlet opening 3

 Flushing around the rod head 2, after the air outlet opening 3, but from here through a bypass channel to the Arheitiizrlinder 5. The partition 4 not only cools the connecting rod head with the associated piston pin and the piston in general, but also preheats the working air to a certain extent brought about.
