A stator (20) for a camshaft adjuster (4). The stator (20) has a ring-shaped outer part (50) for the concentric holding of a rotor (22) with vanes (34) that project in the axial direction and are arranged on the periphery around the rotor (22) and a segment (52) that projects inward in the radial direction from the ring-shaped outer part (50) for engaging between two vanes (34) of the rotor (22), in order to form, together with the two vanes (22), pressure chambers (44) of the camshaft adjuster (4). Here, the segment (52) has a cavity (70) for holding a hydraulic fluid from the pressure chambers (44).
A stator for a camshaft adjuster comprising a ring-shaped outer part for concentric holding of a rotor with vanes that project in an axial direction and are arranged on a periphery around the rotor, a segment that projects inward in a radial direction from the ring-shaped outer part for engaging between two of the vanes of the rotor, in order to form, together with the two vanes, pressure chambers of the camshaft adjuster, and a cavity that is opened to one of the pressure chamber by a non-return valve.
A camshaft adjuster for adjusting a phase position of a camshaft relative to a crankshaft in an internal combustion engine, comprising a paired number of volume-changing advanced and retarded pressure chambers for adjusting a phase position via a rotor with vanes that project in an axial direction and are arranged on a periphery around the rotor mounted in a stator, the stator having a ring-shaped outer part, segments that project inward in a radial direction from the ring-shaped outer part that each engage between pairs of the vanes of the rotor, in order to form, together with the vanes, the advanced and retarded pressure chambers, and a volume accumulator with an accumulator connection for storing hydraulic fluid from the pressure chambers and a tank connection for discharging the hydraulic fluid to a tank, wherein a number of the pressure chambers that is smaller than a total number of all pressure chambers are each connected by an additional channel having a non-return valve oriented toward each of the pressure chambers to the volume accumulator.
