Zusammenfassung:	A directional valve (30) for controlling a hydraulic oil flow from a pressure port (34) via working chambers of a camshaft adjuster (4) to a tank port (58). The directional valve (30) includes an accumulator port (36) for conducting at least a part of the hydraulic oil flowing out of a working chamber into a volume accumulator (54) before said hydraulic oil flows out into the tank port (58), and the accumulator port (36) is connected via a passage (60) to the pressure port (34).
