  • Patent number: 11168590
    Abstract: A sleeve for a cam phaser, wherein the sleeve is arranged between a central valve and a rotor of the cam phaser, wherein the rotor is rotatable relative to a stator of the cam phaser about a rotation axis of the rotor, wherein a vane of the rotor is arranged positionable between two bars of the stator, wherein the vane divides an intermediary space that is formed between the two bars into a first pressure chamber and a second pressure chamber, wherein the rotor is movable by pressures that are provided in the first pressure chamber and in the second pressure chamber, wherein the central valve is configured to provide pressure loading and pressure relief of the first pressure chamber and the second pressure chamber.

  • Patent number: 10781727
    Abstract: A cam phaser for a camshaft, the cam phaser including a stator that is operatively connected with a crankshaft through a drive wheel; a rotor that is connectable torque proof with a camshaft and rotatable relative to the stator, wherein the drive wheel is connected torque proof or integrally configured in one piece with a stator base element or with a stator cover that is connected to and sealed relative to the stator base element, wherein a vane of the rotor is arrangeable between two bars of the stator and an intermediary space that is configured between the two bars is divided by the vane into a first pressure cavity and a second pressure cavity.
