Abstract: An internal combustion engine piston is fitted with bushes between its piston pin and the cross bore in the piston. The diameters of the piston pin and the piston cross bore are dimensioned independently of each other to meet the requirements imposed upon them, which allows the piston pin to be dimensioned only to such size as is required to withstand the bending stress imposed by the connecting rod, thus permitting the size of the piston pin and the reciprocating mass to be reduced in relation to conventional practice.

Abstract: A piston incorporating a thermal barrier is produced by first making an annular piston ring carrier insert from steel. The insert comprises an annular body to the upper and lower radially-inner edges of which are secured the upper and lower edges of an annular element which is channel shaped in radial cross-section and the channel in which faces radially outward. The element is soldered or welded to the insert body so that an enclosed annular space is defined between the element and body. The insert thus formed is then heated in molten aluminium to "alfinize" its external surface. The treated insert is subsequently placed in a piston mold and the piston is molded about it from aluminium.

Abstract: In a machine housing with a relatively thin-walled structural member which at least partially encloses a space containing at least a small quantity of liquid and in which vibrations are produced mechanically, pneumatically and/or hydraulically, at least one element is provided between facing wall portions of the member and/or between a wall portion of the member and a facing wall portion of an adjacent part of the housing for preventing the occurrence of unacceptably loud noise resulting from the vibrations, the element extending between the wall portions while leaving open a gap accessible to the liquid.

Abstract: A component subjected to zonally differential thermal stress for engines, machinery or other devices, in particular a component for combustion engines. In these components, in order to arrange more favourably the stress variation as a function of temperature in the thermally highly stressed parts or regions, so that the adjoining colder regions do not reduce or hinder its expansion, in the material of the component, for example a piston of a combustion engine, in the neighbourhood of the zones of higher thermal loading, at least one closed hollow chamber is provided which is completely filled with a substance which has a higher coefficient of thermal expansion than that of the material of the component surrouding the chamber.

Abstract: Piston for combustion engines consisting of an upper part forming the piston crown and a lower part forming the piston body. These two piston parts abut via annular contact surfaces in the piston axial direction and are coupled together via a gudgeon pin or a gudgeon pin bushing. In order to arrange such an unscrewed piston in such manner that its upper part need not be constructed to be rigid and heavy as in an articulated piston with pendulum shaft and that the construction of cooling channels between the upper and lower parts is possible without excessive expenditure and the constructional height of the piston can be small, the contact surfaces are mutually prestressed in the direction of the piston axis in that the gudgeon pin bore in the one piston part is arranged to be offset relative to the gudgeon pin bore in the other piston part in the unstressed condition in the direction of the piston axis. In this connection, the offset can amount to 0.5 to 10 parts per thousand of the piston diameter. By this offset according to the invention a substantially rigid inter-engaged and frictionally inter-locking coupling between the two piston parts is ensured.
