Document Type and Number:
WIPO Patent Application WO/2023/168566
Kind Code:
A1
Abstract:
The present invention relates to a cam phase regulator assembly. The cam phase regulator assembly comprises a stator, a rotor, and an engine oil control valve, the rotor is rotatably mounted on the radial inner side of the stator, the engine oil control valve comprises a valve core and an elastic piece, and the valve core is mounted on the radial inner side of the rotor in a manner of being movable in the axial direction. The cam phase regulator assembly further comprises a retaining plate mounted at an axial end of the rotor, a hydraulic flow channel leading to the rotor is provided on the retaining plate, and the elastic piece is abutted between the retaining plate and the valve core along the axial direction. The cam phase regulator assembly of the present invention has an improved structure.
