Abstract (en)

[origin: EP2487339A2] The adjuster (1) has a stator (2) and a rotor (3) including a set of radially orientated vanes (5), where the stator and rotor are rotated relative to each other. The vanes of the rotor and stator form working chambers (A, B) that act opposite to each other, where the working chambers are supplied with a hydraulic medium to rotate the rotor relative to the stator. A pressure accumulator (6) stores the medium and includes a control vane (11) i.e. sheet metal plate, where the vanes of the rotor or stator are projected around the control vane. A control spring (19) acts on the control vane.
