摘要： A parallel guide portion as an integral structure of a sprocket and a vane, as well as a slant guide portion, are arranged alternately on the same circumference, with circumferential gaps being formed between said guide portion and the parallel guide portion, said guide portion having a shape such that the circumferential gaps become smaller in one axial direction of a cam shaft. Wedge members are disposed in the circumferential gaps respectively and are moved in one axial direction to fill up the circumferential gaps, thereby fixing the phase between the sprocket and the vane into a locked state. The wedge angle of each wedge member is set sufficiently small and, by utilizing varying torques acting on the cam shaft, said members are each moved and locked in one axial direction with a spring. Said members are actuated in an opposite axial direction with oil pressure to release the locked state, thereby permitting a phase angle control. By utilizing a varying torque acting on the cam shaft, the phase of the cam shaft is returned for itself to an intermediate position and is locked without looseness.

摘要： A plurality of advanced angle chamber oil paths communicated to advanced angle hydraulic chambers and a plurality of retarded angle chamber oil paths communicated to retarded angle hydraulic chambers according to a change in rotating angle of a cam shaft are provided. The plurality of advanced angle chamber oil paths and the plurality of retarded angle chamber oil paths, respectively, are switched between communication and cut-off according to a rotating angle of the cam shaft. When torque in the direction of advanced angle acts in an advanced angle mode for phase shifting in the direction of advanced angle, the advanced angle hydraulic chambers are caused to communicate to a hydraulic power source and the retarded angle hydraulic chambers are caused to communicate to a drain. Also, at high speed of an engine, in the advanced angle mode, shut-off valves in the advanced angle chamber oil paths and the retarded angle chamber oil paths are opened so that hydraulic pressure is communicated from the hydraulic power source to the advanced angle chambers at all times in the same manner as in the related art.

摘要： An intake- and/or exhaust-valve timing control system for internal combustion engines in which a ring gear mechanism is provided between a timing pulley and a cam shaft for adjusting the phase angle between the pulley and the cam shaft. A drive mechanism is also provided for driving the ring gear mechanism depending upon the operating state of the engine. The drive mechanism includes a hydraulic circuit having oil supply and exhaust passages, a flow control valve having a spool valve for controlling the amount of working fluid flowing through the hydraulic circuit, a controller for monitoring the operating state of the engine, and an electromagnetic actuator having a plunger rod for actuating the flow control valve in response to the control signal from the controller. The flow control valve and the actuator are integrally mounted in the cylinder head. Therefore, relative friction between the facing ends of the spool valve and the plunger rod is avoided.
