Hydraulic angle-of-rotation adjustment device for combustion engine cam-shaft, has drive-side rotor and cam shaft-side rotor forming separate adjustment compartments by end-face vanes

摘要

A hydraulic angle-of-rotation adjustment device for a cam-shaft, has a locking element (6) in the form of a ball (7) which operates in conjunction with two rotors (2,3) for locking over its equator zone. The ball (7) can be mounted with minimum play, specifically in a guide boring (8) against the resistance of a helical spring (9).
