Claim Text:
1. A device for altering a compression ratio of a reciprocating internal combustion engine, comprising: a crankshaft drive with a crankshaft with at least one crankpin mounted rotatably on both ends thereof; a piston arranged in a cylinder of the reciprocating internal combustion engine; a connecting rod having a functional connection with said crankpin and said piston in a manner allowing conversion a rotational movement of the crankshaft into a bidirectional, translational movement of the piston with a defined stroke height; a rotating eccentric with outer teeth arranged between the crankpin and a connecting rod eye of the connecting rod such that rotation of the rotating eccentric alters the stroke height of the piston; a first gear with outer teeth arranged to rotate the rotating eccentric, the outer teeth of the first gear meshing with outer teeth of the rotating eccentric; a second gear, said first gear being connected in a torque-proof manner axially to the second gear via a shaft arranged parallel to the crankshaft; and a third gear rotatable by a control element, said second gear being arranged on and intermeshing with the third gear, wherein the shaft is arranged parallel and radially distanced from the crankshaft.
