摘要： Disclosed is a valve timing control apparatus capable of avoiding inadvertent realization of a locked state by effectively preventing pulsating pressure of fluid generated in association with torque variation of a cam shaft from having any effect on a fluid passageway used for lock releasing. The apparatus includes a first fluid passageway for feeding/discharging fluid to/from an advanced angle chamber, a second fluid passageway for feeding/discharging fluid to/from a retarded angle chamber, a third fluid passageway for feeding/discharging fluid to/from a locking mechanism capable of locking relative rotation between an inner rotor and an outer rotor, a first switching valve for controlling the feeding/discharging of the fluid to/from the first fluid passageway and the second fluid passageway, a second switching valve for controlling the feeding/discharging of the fluid to/from the third fluid passageway, a pump for feeding fluid to the first switching valve and the second switching valve, and a check valve for inhibiting communication of the fluid from the first switching valve to the second switching valve and allowing communication of the fluid from the second switching valve to the first switching valve.

摘要： A variable valve timing controller for an internal combustion engine includes a hydraulic variable valve timing unit, a lock pin, and a hydraulic control valve. The lock pin is configured to lock the VCT phase at an intermediate lock position. The variable valve timing controller controls a valve drive electric current that is used for actuating the hydraulic control valve. The controller controls the valve drive electric current based on a first control characteristic in the operation of the hydraulic control valve under a first control range. The controller controls the valve drive electric current based on a second control characteristic in the operation of the hydraulic control valve under a second control range. The first control characteristic is different from the second control characteristic.

摘要： A valve timing control apparatus for a valve timing adjusting unit that adjusts valve timing of an engine. The control apparatus learns a reference position. The control apparatus computes an actual phase based on the learned reference position. The control apparatus computes a target phase based on an engine operational state. The control apparatus controls a hydraulic actuator to perform a phase control based on a difference between the target phase and the actual phase. The control apparatus determines whether the lock mechanism is under an abnormal state. When the control apparatus determines that the lock mechanism is under the abnormal state, the control apparatus is prohibited from performing the phase control that uses the reference position.

摘要： A variable valve timing control apparatus for an engine includes a variable valve timing unit, a lock pin, a hydraulic control unit, and a lock control unit. The lock control unit causes the lock pin to lock the camshaft phase at an intermediate lock phase when a lock request is issued. When the lock request is issued, the camshaft phase is shifted in a reference direction to go beyond the intermediate lock phase while the lock pin is urged in a lock direction. When the camshaft phase stops around the intermediate lock phase, the lock control unit changes a control amount of the hydraulic control unit by a certain amount to shift the camshaft phase. The lock control unit determines that the camshaft phase has been locked at the intermediate lock phase when the camshaft phase is not shifted even after the lock control unit changes the control amount.

摘要： During assembly of an improved phaser, a rotor bias spring is captured by a spring retainer that is fitted or formed into the cover, allowing the spring to be installed in a pre-load position and forming a sub-assembly that is then attached to the remaining components. Grounded and active spring tangs are captured in separate slots in the spring retainer. A pocket within the rotor receives the active tang of the bias spring. The pocket has a tapered bottom ramp that lifts the active tang from the slot wall in the retainer and positions the active tang within the pocket in a retarding direction. Lifting the active tang of the bias spring prevents friction between the spring and the retainer slot wall as would occur as the rotor moves in a retarded direction. In advancing, spring rotation stops when the active tang contacts the end of the retainer slot.

摘要： A vane-type camshaft phaser for varying the timing of combustion valves in an internal combustion engine includes a seat formed in the sprocket at the appropriate position of intermediate rotation and a locking pin slidably disposed in a vane of the rotor for engaging the seat to lock the rotor at the intermediate position. A bias spring system disposed on a cover plate urges the rotor toward the locking position from any position retarded of the locking position. A first spring system embodiment comprises a pair of compression spring assemblies. A second spring system embodiment comprises an internal torsion spring. In each embodiment, the phaser may be assembled without having the spring system coupled to the rotor, thereby overcoming a rotor cocking problem inherent in prior art phasers, assuring reliable mounting of an assembled phaser onto an engine camshaft.
