Abstract:
An internal combustion engine comprising:at least one combustion cylinder including a combustion chamber having at least two synchronously controlled gas-exchange valves to control an intake and discharge cross-section; a valve control device having a common valve actuator to actuate the at least two synchronously controlled gas-exchange valves; and a coupling arrangement to connect the at least two synchronously controlled gas-exchange valves to the common valve actuator, the at least two synchronously controlled gas-exchange valves including connection sites that are flexibly formed on the coupling arrangement; wherein the common valve actuator includes a double-acting hydraulic working cylinder having an operating piston that is guided in the working cylinder in an axially displaceable manner and a piston rod that is rigidly connected to the operating piston, the piston rod having a rod section that is fastened to the coupling arrangement and includes a swivel bearing with a swiveling axis oriented transversely to a stroke direction of the operating piston, the swivel bearing being configured to guide the rod section out of the working cylinder.
