Abstract
A piston arrangement including a hollow piston, a piston pin extending within the piston, an intermediate abutment within the piston supporting the pin between its ends, and a transmission member, e.g., a connecting rod, engaging the pin on each side of the intermediate abutment. The intermediate abutment may be supported by the circumferential wall of the piston, or by the piston head, and may be formed as one piece with the piston. The transmission member may have a forked end for engaging the piston pin, the intermediate abutment being between the arms of the fork. The piston pin may be two separate aligned pins each having an end located within the intermediate abutment. The piston, intermediate abutment, piston pin, and transmission member may all be formed of a ceramic material.
