  • Rotor for Camshaft Phaser and Camshaft Phaser
    Publication number: 20220049633
    Abstract: The present disclosure relates to a rotor for a camshaft phaser. A balance groove is formed inside the end face of one axial side of the rotor and inside the end face of the other axial side of the rotor. A through-hole penetrating through the rotor in an axial direction is formed in the rotor, and the balance grooves at the two sides of the rotor are in communication with each other by the through-hole. The rotor can balance gaps between the rotor and two end covers, so that the amount of engine oil leaking from the gaps of an oil chamber can be maintained at a low level, and the probability of hard contact between the rotor and the end covers is reduced, thus also reducing the wear between the rotor and the end covers.
