Abstract
An arrangement for relative angle of rotation adjustment of a camshaft of an internal-combustion engine has an interior part non-rotatably connected with the camshaft and having at least approximately radially extending webs or blades. A driven cell wheel has several cells distributed along the circumference and bounded by webs. The cells are divided by the webs or blades into pressure spaces. Sealing bodies are arranged in recesses provided on faces of the webs or blades. For sealing off the pressure spaces by a hydraulic action, the sealing bodies are pressed against an interior wall of the cell wheel. The sealing bodies are constructed as rollers which, provided with an installation play, are received in the recesses. During operation of the adjusting unit, the rollers, for sealing purposes, form line contacts with the interior wall of the cell wheel and with the lateral walls of the recesses.
