Rotor for a camshaft phaser, and camshaft phaser

Abstract

A rotor for a camshaft phaser includes a hub part having an oil supply passage, at least one vane radially disposed on the hub part, as well as oil channels extending through the hub part and fluidically connected to the oil supply passage. The manufacture of the rotor is considerably simplified because the rotor is made up of a main body and at least one cover element arranged on an end face of the main body. The oil channels are axially closed by the cover element.
