<p>The device for adjusting the phase position of a shaft, especially a camshaft that can be rotated by a drive shaft, more particularly a crankshaft, by a transmission device with at least one transmission wheel, is configured as a rotary piston machine according to the orbit principle. The inventive device adjusts the rotary position of the transmission wheel in relation to the shaft. The rotary pistol machine includes a stator with inner teeth, an annular rotary piston with outer teeth that engage with the inner teeth of the stator, a driven part that can be rotated by the rotary piston and a valve that can be rotated by the rotary piston and a valve device. In order to control the movement of the rotary piston, the valve device enables rotating partial areas of the working area between the stator and the rotary piston to be joined to a fluid supply device at high or low pressure. The fluid supply device includes a control mechanism, a phase position detector and at least one control valve. It enables a theoretical phase position to be adjusted by actuating the valve in a corresponding manner. Fluidic connection to be adjustment device occurs by two angular rotational connections.</p> |
