Abstract

A device for varying the control times of gas-exchange valves of an internal combustion engine, which has between the impeller (8) and the drive wheel (2) an additional angle-limiting device (26) with the aid of which the maximum pivoting angle of the impeller, which is limited per se by the lateral surfaces (15, 16) of the bounding walls (13) in the drive wheel (2), can be reduced with respect to the drive wheel (2) to a smaller pivoting angle.
