Abstract (en)
[origin: EP1277922A2] The mechanism to alter the relative rotary angle of a camshaft (5,6), at an internal combustion motor, has a cellular wheel and a vane wheel (14) within it with relative movement. It is operated by pressure chambers using a hydraulic oil. The oil is fed through axial channels into the pressure chambers which, on one side, are between a shaft with a mounting bolt axially from an end side of the camshaft and a control sleeve around the shaft in at least one holder drilling. On the other side they are between the control sleeve and a hub which is coaxial to the drilling. The control sleeve and the stem of the mounting bolt are inserted from the same end side (12).
