Abstract
A camshaft adjuster (4) including a stator (20) and a rotor (22) which is received in the stator (20) and which can be rotated relative to the stator (20) by a pressure chamber (44), a pressure interface (46, 80) for supplying hydraulic liquid to the pressure chamber (44), and an outflow interface (78) for the discharge of the hydraulic liquid from the pressure chamber (44). The camshaft adjuster (4) also has a third interface (82) for filling the pressure chamber (44) with hydraulic liquid from a volume accumulator (47).
