Abstract

The invention relates to rotor body for a variable valve timing system comprising a main body comprising a front side a back side and vanes tips made from a fibrous reinforced polymeric material a central part comprising an (axial) bore hole made of metal and sealing elements made of a non reinforced polymeric material at the vain tips and at the front side and back side. The invention also relates to a variable valve timing system comprising an assembly of a rotor and a stator receiving the rotor on a camshaft wherein the rotor is a rotor body as described above wherein an end part of the camshaft and/or a fixing element is received in the bore hole and the rotor is fixed at the end part of the camshaft with the fixing element.
