PCT No. PCT/DE93/01005 Sec. 371 Date Jul. 5, 1994 Sec. 102(e) Date Jul. 5, 1994 PCT Filed Oct. 22, 1993 PCT Pub. No. WO94/10429 PCT Pub. Date May 11, 1994.The device for the relative rotation of the shaft of an internal combustion engine with respect to the drive wheel, which is rotatably arranged on the shaft, has a hydrostatic pump whose housing is torsionally securely connected to the camshaft. Within the drive wheel and the pump, there is an electromagnetically actuable control valve which controls the pressure medium connections between the pumps and the setting device (rotary piston control), i.e. it subject the pressure spaces to pressure or relieves them, so that the camshaft is correspondingly rotated relative to the drive wheel. The electromagnet of the control valve is actuated by means of a control unit influenced by sensors. The pressure medium supply to the setting device takes place via a hole in the camshaft. A very compact adjusting device for the camshaft is achieved in this way. |
