Abstract

A control valve (14) for a device (1) for modifying the control times of gas exchange valves (110, 111) of an internal combustion engine (100) is provided. A check valve is arranged inside an annular groove (44) which is formed on one of the components of the control valve (14) and through which a pressurized medium flows. This reduces the assembly costs.
