  • the oil enters through the passage opening 23 into the annular space 33 (arrow 34). A portion of the oil enters through the filter element 17 into its interior (arrows 36) and passes according to the arrow 37 from the filter element 17 unthrottled through the passage opening 18 in the oil control valve 1 (FIG. FIG. 3 ). Another part of the entering into the annular space 33 oil is throttled the camshaft bearings in the oil pressure (calibration element 28) but unrefined fed (arrow 38). Due to the rotation of the camshaft 3, the impurities are centrifugally thrown to the inner wall and taken from the exiting oil flow (arrow 38). The impurities are not harmful to the camshaft 3 or its camshaft bearing, since the camshaft bearings are robust enough, and not need to be protected as the oil control valve 1.
  • a calibration element 27 may be provided with a central calibration or calibration opening in the region of the clear diameter of the filter element 17, so that both the oil control valve 1 and the camshaft bearings purified oil can be supplied.
  • the Aufsplittddling would then no longer in the annular space 33 but within the filter element 17 is arranged.
  • the oil control valve 1 is supplied in accordance with the invention but each unthrottled and purified oil.
  • FIG. 3 can be seen further, the oil control valve 1 supplied and cleaned oil in the inlet area 4 again divided so that a portion of the oil flow to supply the VCT (arrow 39) and the other part (arrow 41) is used to supply the first camshaft bearing 8.
  • the oil control valve 1 is arranged with its space in the region of the camshaft bearing 8 and 9 respectively.
  • the oil control valve 1 with its space outside the camshaft bearing, in particular outside the first camshaft bearing 8 is arranged.
  • the filter element 17 with its shut-off element 32 and the calibration element 28, for example, in the zu FIG. 4 described embodiment in the region of the first camshaft bearing 8 is arranged.
  • splitting of the oil flow entering the camshaft 3 takes place in the region of the first camshaft bearing 8.
  • a splitting in the oil control valve 1 can be omitted.
  • the purified oil passes through the through hole 18 in the oil control valve. 1
  • an improved medium control element 1 or oil control valve is provided with the invention, or with the passage opening 18 in the connection region 2, wherein both the oil control valve 1 and the VCT and the camshaft bearing are supplied via a common oil supply line in the cylinder head with oil ,
  • the passage opening 18, which opens the oil control valve 1 to the hollow camshaft 3, is easy and inexpensive to produce in any diameter.
  • the passage opening itself is calibrated, or by means of Calibratable calibration elements. As a result, a smaller volume flow is effected to the camshaft bearings, wherein the cylinder head oil space advantageously a smaller amount of oil is supplied.
  • oil drain shafts can be made smaller.
  • Another advantage is that the oil flow in the direction of the OCV or VCT, however, is not reduced or throttled. Rather, a larger volume flow is supplied to the OCV or VCT, which has an advantageous effect on the adjustment times.
  • the oil pump can also be designed adapted in their performance, which leads to a lower pressure-conveying capacity and thus lower weight, space required, fuel consumption and costs.
