ABSTRACT:
A device for providing angular adjustment between two drivingly connected shafts utilizes a positioning piston which can be moved axially between a driven sprocket wheel carrier and a flanged shaft connected to a camshaft so as to divide a hollow space formed by sprocket wheel carrier and flanged shaft into two working spaces. The positioning piston is positively connected both to the sprocket wheel carrier and to the flanged shaft via helical toothings. Depending on the position of a control piston arranged in the hollow flanged shaft, pressure oil is channelled out of the engine oil circuit into into one working space or the other and displaces the positioning piston in the axial direction. Via the two helical toothings, this longitudinal displacement of the positioning piston brings about a relative rotation of the camshaft with respect to the driven sprocket wheel carrier. Adjustment in both directions is effected by a hydraulic arrangement alone, without any auxiliary force.
