Length-adjustable connecting rod having stop surfaces

A length-adjustable connecting rod for a reciprocating piston engine, the connecting rod comprising:

• a first connecting rod part;
• a second connecting rod part, wherein the second connecting rod part has a section with a guide cylinder on its end facing the first connecting rod part,
• wherein the first connecting rod part has a guide shank corresponding in form to the guide cylinder on its end facing the second connecting rod part,
• wherein the guide shank of the first connecting rod part is at least partly accommodated by the guide cylinder in a functional state of use of the connecting rod and is movable relative to the guide cylinder for adjusting an effective length of the connecting rod,
• wherein the first connecting rod part comprises a first stop surface and the second connecting rod part comprises a second stop surface,
• wherein the first stop surface lying against the second stop surface restricts a relative movement between the first connecting rod part and the second connecting rod part in a first direction, and
• wherein the connecting rod is designed such that when the first stop surface lies against the second stop surface, at least a portion of a compressive force acting on the connecting rod along a longitudinal axis of the connecting rod is transferred past the guide shank via the first stop surface and the second stop surface from the first connecting rod part into the second connecting rod part and/or from the connecting rod part into the first connecting rod part.
