Beschreibung
Zusammenfassung:	A valve timing control device for an internal combustion engine. The valve timing control device includes a rotor (10) connected to a camshaft (64) and having a plurality of vanes(14). A stator (40) is engaged with the rotor (10), and includes a plurality of webs (46). Pressure chambers (60,62) are provided between each of the webs and vanes. A centering slot (54, resp. 34) is provided on the stator (40) and/or the rotor (10). A pressure medium control valve (28) is disposed in one of the vanes (14) of the rotor, and is configured to not only selectively lock and unlock the position of the rotor relative to the stator, but is also configured such that pressure medium in the pressure chambers is ventable through the centering slot and thereafter through the pressure medium control valve.
