Abstract: In a composite, liquid-cooled piston, the upper part consists of ferrous material and is joined by conventional means to the lower part. A ring is provided on the underside of the upper part which bears on the corresponding surface of the lower part and constitutes a radially inner boundary of a cooling passage which is disposed on the upper part and open to the interfacial plane. To improve the cooling action in the hottest regions of the upper part and to achieve a more uniform distribution of temperature in the ring carrying over of the upper part of piston, the upper portion of the wall defining the cooling passage is coated with a material having a high thermal conductivity.

Abstract: A composite piston for internal combustion engines has an interior cooling chamber and an outer cooling passage. An annular rib protrudes from the inside surface of the upper part and that surface of the lower part which faces that annular rib. An annular flange is clamped between said rib and said surface of the lower part. A tongue which protrudes into the cooling passage is provided on that edge of said flange which faces the cooling passage. In order to minimize the temperature of that surface of the cooling passage which is near the combustion chamber and to maintain at least adjacent to the uppermost ring groove a temperature which is sufficient to prevent a wet corrosion of the piston and of the piston rings, the tongue defines a relatively narrow annular gap with that surface of the cooling passage which is near the combustion chamber so that the coolant oil is throttled as it flows through that gap.

Abstract: In a cooled composite piston having a cooling passage adjacent to the interface and a method of making same, the upper part consists of forged steel and is formed on its underside with ribs bearing on mating surfaces of the lower part. To improve the resistance to thermal and mechanical stresses, the upper part has been welded by means of charge carrier rays to the lower part, which consists of cast ferrous material.
