Abstract
A stator (20) for a camshaft adjuster (4). The stator (20) has an outer part (50) for concentrically holding a rotor (22) with vanes (34) arranged around the rotor (22) and a segment (52) projecting from the 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).
