Patent ID: 7647905

Claim:
A device for the variable setting of the control times of gas exchange valves of an internal combustion engine, having an inner rotor arid an outer rotor, with one of the components being rotationally fixedly connected to a camshaft and the other component being drive-connected to a crankshaft, with the outer rotor being rotably mounted on the inner rotor and at least one hydraulic chamber, which is delimited by side walls and the inner rotor, being formed on the outer rotor, with the inner rotor having a hub part and at least one vane, with a vane of the inner rotor extending into each hydraulic chamber and dividing the latter into two pressure chambers which act counter to one another, with a groove being formed on a face, which faces towards the other component of the inner rotor or of the outer rotor, in which groove is arranged a sealing strip, and with metal spring element at least partially coated with or encased by a coating material being arranged between a groove base of the groove and the scaling strip, which spring element forces the sealing strip in the direction of an opposing face of the other component, wherein the spring element is simultaneously designed as a sealing element and at least largely prevents a flow of hydraulic fluid from the one side face of the sealing strip via the groove base to the other side face of the sealing strip.
