A control device for hydraulic media with a control valve, in particular, a proportional valve that has a sleeve housing provided with radial openings, wherein at least one pressurized flow feed line, at least one control line, and at least one return line are connected to the openings, and the opening for the pressurized flow feed line is connected to a ring-shaped groove, with a control slide that has control edges and is supported in the sleeve housing so that it can move in the axial direction and is actuated by an electromagnetically constructed control unit, advantageously for controlling a phase adjustment device for the variable adjustment of the control times of gas exchange valves of a reciprocating piston internal combustion engine. A non-return valve is installed in the pressurized flow feed line or in the ring-shaped groove that is arranged in the sleeve housing.
