  • Patent number: 9957850
    Abstract: A method of controlling a lock pin of a CVVT (continuous variable valve timing) system is provided. The method includes an oil supply operation of operating a spool of a valve bolt by means of oil drawn into the CVVT system and supplying the oil to the lock pin and a switching valve. The method further includes a switching-valve opening operation of opening the switching valve by means of pressure of the oil supplied in the oil supply operation, and a lock-pin releasing operation of supplying oil to a chamber when the switching valve opens and releasing the lock-pin when there is no difference in oil pressure between an advanced chamber and a retracted chamber.

  • Patent number: 9909464
    Abstract: An intermediate phase adjustment apparatus of intermediate phase continuous variable valve timing includes chambers and a diverter valve balancing oil pressure between the chambers. The chamber includes an advancing chamber and a retarding chamber formed between a rotor and a stator and supplied with oil through an oil channel. The diverter valve balances oil pressure between the chambers by sliding along an oil line through which the oil moves only in one direction between the chambers so that the oil selectively moves from a chamber having higher pressure to a chamber having lower pressure due to a pressure difference.
