Abstract
A variable valve timing system includes a relative rotation controlling mechanism restricting relative rotation of a housing member and a rotor member at the intermediate lock phase between the most advanced angle phase and the most retarded angle phase. An auxiliary controlling mechanism actuated in response to the operation fluid to be supplied to and discharged from a fluid pressure circuit allows the relative rotation of the housing member and the rotor member under the unlock condition and restricts the rotation of the rotor member to the retarded angle side or to the advanced angle side relative to the housing member at a set phase between the most retarded angle phase or the most advanced angle phase and the intermediate lock phase under the lock condition.
