ABSTRACT:
To avoid the necessity of piston rings in a piston-cylinder set, it is prsed that the cylinder liner be surrounded by a band consisting of a fiber composite whose thermal expansion in a radial direction is less than that of the cylinder liner, the impediment to expansion presented by the band varying over the length of the cylinder housing; that the piston be constructed with a cap consisting of a piston head facing the combustion chamber and an essentially cylindrical piston skirt adjacent to the cylinder bearing surface, and a force-transmitting core that contains the bearing for the piston pin and the spherical pressure pad; that a force-transmitting connection rotationally symmetrical to the piston's longitudinal axis be provided above the spherical pressure pad; that the cap be connected at the lower edge of the piston skirt to the force-transmitting core, but otherwise no contact be provided between cap and force-transmitting core except in the area of the force-transmitting connection; and that both cylinder liner and cap be fabricated from ceramic material.
