| titleOfInvention | ALLOY CONTROL PISTON |
| abstract | The invention relates to control elements for light metal piston of internal combustion engines made of a material with a smaller thermal expansion coefficient than that of the piston material, which are cast on the Innenmantelflaeche the bearing Kolbenschaftflaeche (pressure back pressure level) and the control elements in the circumferential direction one or more elongated recesses at the ends slotted and deformed in the inner direction of the piston, have and the outer shape of the piston is formed parabolically multiply, with which the outer shape of the piston is influenced by the control elements so that it is singly or multiply parabolically wedged and hydrodynamically favorable lubricating conditions arise and at the same time occurring traction forces of the control elements are added. According to the invention, this object is achieved by the fact that the recesses in the supporting plane become smaller, through this configuration of the recesses the tasks can be performed; Influence on the outer contour of the piston and absorption of the necessary traction forces, to be fulfilled in combination.
