Abstract

A camshaft adjuster (1) having a stator (3) and a rotor (5) located in the stator (3), having vanes (7) that are each located in a chamber (9) formed between the stator (3) and the rotor (5), each of the vanes (7) dividing its respective chamber (9) into two partial chambers, and pressurized oil being adapted to be supplied to each of the partial chambers and conducted out from each of the partial chambers via oil channels (21), so that through the pressurized oil a torque can be exerted on the rotor (5) by which the rotor (5) can be rotated, so that a camshaft adjustment can be set thereby. The rotor (5) is constructed from a metallic base frame (15) that has, axially adjacent, a casing (17) made of plastic in which at least one of the oil channels (21) is formed.
