Abstract

A hydraulic vane-type camshaft adjuster, having a stator and a rotor arranged therein such that the rotor can rotate during control mode, wherein the rotor and the stator form at least two working chambers and are separated by a vane. A locking pin immobilizes the rotor in a rotationally fixed manner in relation to the stator wherein the locking pin is connected to an active accumulator, which deflects the pin if required. The active accumulator is arranged below a rotation axis on a camshaft. A method is also provided.
