Kolben-Zylinder-Baueinheit

摘要

In a piston-cylinder assembly with a shaftless piston (1), the aim is to improve the lateral guidance of the connecting rod, to reduce edge wear and the seizing tendency in the event of fault during the combustion process. Consequently, the piston (1) has at least one supporting ring (9) form-fittingly on the bosses (3) which guides in the cylinder the piston (1) along with the piston head.
