Abstract
A vane-type camshaft adjuster () including a rotor () which has radially projecting vanes () and forms vane cells () along with a stator () rotatably accommodating the rotor (), each vane cell () being subdividable by a vane () into two adjustable chambers provided for holding hydraulic fluid; a hydraulic fluid-controlling device () for conducting hydraulic fluid is disposed and/or connected between the chambers () in such a way that a drop in pressure in the chambers () caused or reinforced by camshaft switching moments occurring during operation is used to open the hydraulic fluid-controlling device () such that fluid flows therethrough.
