Abstract

The invention concerns a device for the hydraulic adjustment of the angular position of a shaft (1) relative to a drive pinion (14), said device comprising a plate (2) fixed to the shaft to cooperate with the drive pinion (14) or with a component fixed to the drive pinion. The device comprises at least one ring-segment shaped section (2a) in the plate (2) and a means (4a) arranged on the drive pinion (14) or on said component to cooperate with the shaped section (2a) so as to divide the shaped section into two separate chambers (10, 11). The device further comprises a means for a selective hydraulic pressurization of the chambers (10, 11) for adjusting the relative angular position of the drive pinion (14) and the shaft (1).
