Abstract:
A device for changing an angle of rotation of a camshaft of an internal combustion engine relative to a driving wheel, comprising:an inner part which is fixedly connected with the rotatable camshaft and having bridges extending substantially radially; and a wheel having a plurality of cells distributed over a periphery of the cell wheel, the plurality of cells being bounded by bridges formed on the cell wheel and each cell being divided by the bridges of the inner part into two pressure spaces, wherein the camshaft is rotatable between two end positions relative to the cell wheel by the application of a pressure medium on or relieving the pressure medium from the two pressure spaces, wherein a change in a rotation position of the camshaft is damped hydraulically by integrated damping agents before one of the two end positions is reached, and wherein a throttle chamber is formed by a recess in a bridge of one of the inner part and the cell wheel and an adjoining projection in a neighboring bridge of the other of the cell wheel and of the inner part.
