PCT No. PCT/EP97/03943 Sec. 371 Date May 10, 1999 Sec. 102(e) Date May 10, 1999 PCT Filed Jul. 22, 1997 PCT Pub. No. WO98/07966 PCT Pub. Date Feb. 26, 1998A system for angular adjustment of a shaft relative to a driving gear, preferably of a camshaft of an internal combustion engine, includes a hydraulically controllable angular adjustment device rotating with the shaft and having hydraulic supply ducts in a non-rotatably fitted end cap and oil distribution ducts, associated with the supply ducts, in the angular adjustment device. The end cap is provided in its inner circumferential region facing the direction of adjustment with at least one recess shaped to receive an oil distribution ring. The oil distribution ring is shaped so as to be connectable non-rotatably to the end ring and to be movable transverse to the common axial direction, and the internal diameter of the recess is greater than the external diameter of the oil distribution ring. Through the movability of the oil distribution ring relative to the end cap, deviations between the position of the camshaft, which determines the position of the oil distribution ring, and the position of the end cap can be compensated for during assembly of the system. Furthermore, in order to form two separate oil supply ducts it can be provided that the internal circumference of the end cap and the external circumference of the oil distribution ring are stepped.
