A device for the variable setting of the control times of gas exchange valves of an internal combustion engine, having an inner rotor (3) and an outer rotor (4), with one of the components being rotationally fixedly connected to the camshaft (2) and the other component being drive-connected to a crankshaft, the outer rotor (4) being rotatably mounted on the inner rotor (3) and, at least one hydraulic chamber (7), which is delimited by side walls (5, 6) and the inner rotor (3), is formed on the outer rotor (4), the inner rotor (3) comprises a hub part (3b) and at least one vane (3a), with a vane (3a) of the inner rotor (3) extending into each hydraulic chamber (7) and dividing the latter into two pressure chambers (10, 11) which act counter to one another. A groove (8) is formed on a face, which faces toward the other component, of the inner rotor (3) or of the outer rotor (4), in which groove (8) is arranged a sealing strip (9), and with a spring element (13) being arranged between a groove base (12) of the groove (8) and the sealing strip (9), which spring element (13) forces the sealing strip (9) in the direction of an opposing face of the other component with the spring element (13) simultaneously being designed as a sealing element.
