摘要： A valve timing control apparatus is adapted to an exhaust valve side of an internal combustion engine. A vane member is arranged to rotate with a camshaft relative to a timing sprocket member. The vane member is rotated at low speed engine operation dominantly by a camshaft-torque actuation mechanism and at high speed engine operation dominantly by a hydraulic actuation mechanism. The camshaft-torque actuation mechanism is actuated by an alternating torque of the camshaft, whereas the hydraulic actuation mechanism is actuated by a fluid pump. The vane member includes a first vane arranged to operate in the camshaft-torque actuation mechanism and a second vane arranged to operate in the hydraulic actuation mechanism. The first vane has a shorter radial length and a smaller pressure-receiving area than the second vane.

摘要： A variable valve timing control apparatus employs a five-blade vane member fixedly connected to a camshaft end and rotatably disposed in a phase-converter housing formed integral with a sprocket driven by an engine crankshaft. Five phase-retard chambers and five phase-advance chambers are defined by five blades of the vane member and the housing, for creating a phase change of the vane member relative to the housing. A circumferential width of each of a first pair of blades, located on both sides of a first blade having a maximum circumferential width, is dimensioned to be less than a circumferential width of each of a second pair of blades, circumferentially spaced apart from the first blade rather than the first pair. The circumferential width of each of the second pair of blades is dimensioned to be less than the maximum circumferential width of the first blade.
