ABSTRACT:
A piston for medium-speed internal combustion engines having a ring groove for receiving a compression piston ring. The upper and lower flanks of the ring groove when the engine is cold deviate from a plane-parallel position in relation to the adjoining upper and lower flanks respectively of the ring to such an extent that under the mechanical and thermal loading of the combustion gases in operation of the engine under rated load they are deformed into a position plane-parallel with the flanks of the ring.
