Kolben fuer Rotationskolbenmaschinen

摘要

The rotor of a rotary internal combustion engine has a lobed light metal body and a steel sleeve in a central axial bore of the body. The bearing which supports the rotor on an eccentric is mounted in the sleeve and protected against the heat absorbed from the burning fuel by the rotor body by a sealed annular chamber between radially opposite walls of the body and the sleeve.
