摘要： A piston for an internal combustion engine has a lower piston part and an upper piston part disposed on the lower piston part. The upper piston part has a top land that runs around its circumference, and a ring belt that runs around its circumference. At least the upper piston part consists of a sintered material.

摘要： The invention relates to a camshaft made of cast steel having an inner cavity with a cylindrical inner shape, especially a profiled cylindrical inner shape produced rationally according to a lost-foam casting method known per se. A steel camshaft thus produced exhibits a long service life and can withstand extremely high hertzian surface pressures on its bearing surfaces without any damages.

摘要： A cylindrical bushing sleeve or another cast part, in particular a ring carrier for pistons, has a rough surface so that the surrounding cast material can cling to the cast part as required. The rough surface is created by producing the cast part with the aid of a lost mold provided with a particulate layer.

摘要： The invention relates to a sintered metal rotor of a rotary piston pump, comprising a pot-shaped base (1) and a journal element centrally projecting from the bottom of said base (1). Said journal element comprises a base section and an adjoining connecting claw section (2) for a coupling element to be joined thereto. The rotor is characterized in that the connecting claw section (2) is configured in the form of two prominent single webs (3). Said single webs (3) are located at a diametrical distance to each other in the periphery of the cylindrical base section in one area each that is limited, in terms of its periphery, to not more than 100°. and radially to not more than 25% of the diameter of the cylindrical base section. The two connecting claw single webs (3) are pressure-sintered by means of single pressure rams that are designed for the cross-sectional areas thereof and that are actuated separately from the sinter pressure rams required to produce the rotor.
