    Patent number: 5896836
    Abstract: A valve control device for an internal combustion piston engine adjusts positions of rotation of a camshaft relative to a crankshaft. This device comprises a hydraulic cylinder (1) comprising a piston (2) and at least one first feed duct (4). Between the cylinder (1) and a hydraulic pump (8), there is disposed a hydraulic valve arrangement (6) by which a hydraulic connection can be established between the first feed duct (4) and a first outlet duct. To assure a reliable prevention of rattling noises during the starting operation, it is proposed that the first outlet duct (10) open into a fluid reservoir (7) below the level of liquid therein.
