In a phase change mechanism in which the phase of a driven member (10) relative to a drive member (12) is adjusted by axial displacement of an actuating rod (30) connected to the piston (50) of a hydraulic jack rotatable with the drive and driven members, the cylinder (52) of the hydraulic jack has a double-skinned wall, and the gap (54) between the two skins of the cylinder wall serves as a passage for supplying oil to and from one of the working chambers of the hydraulic jack.
