  • Variable camshaft phaser with magnetic locking cover bushing
    Patent number: 10954828
    Abstract: A variable camshaft phaser is provided having a stator attached to a driving part, and a rotor located within the stator and attached to a driven part. First and second cover plates are located on respective first and second axial sides of the stator. Inwardly directed vanes of the stator, the rotor, and the first and second cover plates define at least one chamber. Radially outwardly directed vanes of the rotor divide the at least one chamber into an advance side working chamber and a retard side working chamber. A locking pin bore is located in the rotor, and a locking pin is located in the locking pin bore. One of the first and second cover plates includes a locking pin receiving opening. A magnetic part is located in the locking pin receiving opening to remove metallic particles and contaminants from the flow of pressurized hydraulic fluid.
