摘要

The actuating device (10) comprises an actuating portion (12), by which a compression ratio of a cylinder of a reciprocating piston engine is variably adjustable corresponding to the actuating device. The actuating portion is formed as synchronized cylinder with a displaceable piston (20) received in a working chamber (22). An independent claim is also included for a method for operation a reciprocating piston engine.
