OIL GALLERY FOR CONTINUOUSLY VARIABLE VALVE TIMING APPARATUS OF A CYLINDER HEAD

摘要

An oil gallery for continuous variable valve timing apparatus of a cylinder head comprises to discharge easily the bubble reaching the CVVT journal through an oil supply path through a thin gap which is formed by a CVVT journal. An oil gallery for continuous variable valve timing apparatus of a cylinder head comprises an oil supply path(120) which is connected to a CVVT(Continuously Variable Valve Timing) journal(140) from a groove(110) for OCV in which an OCV(Oil Control Valve) is inserted; and an oil supply path(130) which is connected to the CVVT journal from the groove for OCV. An oil chamber(200) having an inclined loop is formed in one or more oil supply paths of the oil supply paths.
