    摘要: Apparatus for adjusting a rotational relation between a camshaft and a timing pulley of an internal combustion engine of a type having a crankshaft for driving the timing pulley and a cylinder head for rotatably supporting the camshaft, includes a housing receiving a double-acting piston for displacement in an axial direction between two axially spaced end positions and defining with the housing two pressure compartments. Secured to the piston is a control bushing which is geared to the timing pulley via a first gearing and operatively connected to the camshaft via a second gearing. A hydraulic regulating unit is fluidly connected to the pressure compartments via fluid-carrying passageways for alternately supplying a pressure fluid to the pressure compartments to effect an axial displacement of the piston and thereby a positional adjustment of the control bushing, with the fluid-carrying passageways including, for movement of the piston into one of the end positions, two axially spaced distribution spaces which are fluidly connected to each other by transition zones arranged in angularly offset disposition.
