Abstract: A device for hydraulic control of gas exchange valves of a reciprocating internal combustion engine which has slave cylinders, in operative connection with one or more gas exchange valves and, master actuators, in operative connection with at least one cam provided with a basic and cam profile of a camshaft that is rotatatly driven by the engine and can be hydraulically connected to the slave cylinders. The device also has a control device controlled by an actuating member, the device controlling the volume of hydraulic liquid fed to the slave cylinders, and at least one feed line, via which low pressure liquid from a pressure source can be fed to the device by means of at least one non-return valve. The actuators have displaceable vanes, a component carrying the vanes, and cells limited by walls. The vanes are in operative connection with the basic and cam profile of the cam.
