ACTUATING DEVICE FOR VARIABLY ADJUSTING A COMPRESSION RATIO OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to an actuating device (10) for variably adjusting at least one compression ratio of an internal combustion engine, in particular of a reciprocating-piston internal combustion engine, having at least one motor (16) for variably adjusting the compression ratio and having at least one brake device (36) for holding the set compression ratio, said motor and brake device being assigned at least one common component (20) or the like by means of which the compression ratio can be adjusted and held, wherein the brake device (36) and the motor (16) are integrated into at least one common housing part (22) of the actuating device (10).
