Abstract

A camshaft adjuster (4) with a stator (20) that 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). A cover (1564, 156) is located on an axial side of the ring-shaped outer part, and the cover includes a cavity for holding hydraulic fluid from the pressure chambers (44). The segment (52) may also have a cavity (70) for holding a hydraulic fluid from the pressure chambers (44).
