Device for hydraulically adjusting the angle of rotation of a shaft in relation to a driving wheel

摘要

A device for changing the angle of rotation of a camshaft of an internal combustion engine relative to a driving wheel. The device includes an inner part, which is provided with bridges or wings, and is disposed rotationally movable in a cell wheel. The driven cell wheel has several bridges, which are distributed over the periphery and divided by bridges or wings of the inner part into in each case two pressure spaces. The change in the angular position is caused by applying pressure on or relieving pressure from the two pressure spaces. As an end position is approached, the adjusting movement is damped hydraulically by integrated damping means. These damping means are formed by the interaction of the mutually approaching bridges of the inner part and of the cell wheel.
