摘要： A valve timing controller includes a guide rotation member provided with a guide groove, a bearing rotation member radially supporting the guide rotation member, and a plurality of movable bodies sliding in the guide groove in accordance with a rotation of the guide rotation member. A plurality of link mechanisms connects the bearing rotation member with each one of movable bodies respectively, and rotates the bearing rotation member in accordance with a movement of the movable bodies. The valve timing of at least one of the intake valve and the exhaust valve is adjusted in accordance with a rotation of the bearing rotation body. A clearance gap is provided between the guide rotation member and the bearing rotation member in order to permit a relative radial movement of the guide rotation member with respect to the bearing rotation member.

摘要： The variable valve timing controller controls the valve timing of the intake valve. The variable valve timing controller has a phase adjusting mechanism which includes a first rotating member, a second rotating member, a first arm, and a second arm. The first rotating member rotates in synchronism with a driving shaft and the second rotating member rotates in synchronism with a driven shaft. The first arm is pivoted on the first rotating member and the second arm is pivoted on the second rotating member and the first arm. The phase adjusting mechanism varies the rotational phase of the driven shaft relative to the driving shaft with converting the a movement of the first arm and the second arm into the rotational movement of the first rotating member and the second rotating member.

摘要： Upon transmission of a first torque from a first brake portion to a first eccentric shaft, the first eccentric shaft rotates in a retarding direction relative to a rotating member. This causes a first planetary gear to rotate in an advancing direction together with a first output shaft and a driven shaft. Upon transmission of a second torque from a second brake portion to a second eccentric shaft, the second eccentric shaft rotates in a retarding direction relative to the rotating member. This causes a second planetary gear to rotate in the advancing direction together with a second output shaft and the first eccentric shaft, relative to the rotating member, while maintaining rotation in the advancing direction relative to the second eccentric shaft and causes the first planetary gear to rotate in the retarding direction together with the first output shaft and the driven shaft relative to the rotating member.

摘要： A stopper piston is fitted into a fitting hole when a vane rotor is located at an approximately intermediate position between a most retard position and a most advance position with respect to a shoe housing. When the stopper piston is fitted into the fitting hole, a relative rotation of the vane rotor with respect to the shoe housing is restrained. When the stopper piston rotates to an advance side with respect to the shoe housing over the intermediate position at which the stopper piston is fitted into the fitting hole, a damper chamber communicates with an advance oil pressure chamber through a through hole, an oil passage and a recess space. When the vane rotor rotates to a retard side including the intermediate position, the damper chamber is sealed hermetically, and therefore the moving speed of the stopper piston toward the fitting hole decreases.

摘要： A variable valve timing device includes a control valve for switching fluid communication among ports. The control valve includes a sleeve, a spool, a movable member, and resilient members. A first resilient member pushes the spool in both of the regions. A second resilient member acts on the spool via the movable member engaged with the spool in an advancing region. In a lock region, the movable member rests on the sleeve to enable the spool to move freely from the second resilient member. As a result, force acting on the spool can be restricted in the lock region. The movable member is supported from a radial inside by the spool and is radially distanced from the sleeve. As a result, it is possible to reduce a sliding resistance acting on the movable member.

摘要： An advancing check valve is placed in an advancing connection passage of a spool to enable a flow of hydraulic fluid in a first direction from a retarding port side toward an advancing port side upon placement of the spool in an advancing position and to limit a flow of hydraulic fluid in a second direction from the advancing port side toward the retarding port side upon placement of the spool in the advancing position. A retarding check valve is placed in a retarding connection passage of the spool to enable a flow of hydraulic fluid in the second direction upon placement of the spool in a retarding position and to limit a flow of hydraulic fluid in the first direction upon placement of the spool in the retarding position.

摘要： In the case where an intake valve has its phase in a first region between a most retarded angle and CA(1), the rotational speed of relative rotation between an output shaft of an electric motor and a sprocket is reduced at a reduction gear ratio R(1) to change the phase of the intake valve. In the case where the intake valve has its phase in a second region between CA(2) and a most advanced angle, the rotational speed of relative rotation is reduced at a reduction gear ratio R(2) to change the phase of the intake valve. As long as the rotational direction of relative rotation is the same, the phase of the intake valve is changed in the same direction for both of the first region between the most retarded angle and CA(1) and the second region between CA(2) and the most advanced angle.

摘要： A valve timing adjusting device sets an amount of phase shift of a driven shaft with respect to a drive shaft. A first hole in a first rotor forms a first track extending in order to vary its radial distance from a rotation center line. The first hole makes contact with a control member passing through the first track, on the two sides of the first hole toward which the first hole (the first rotor) rotates. A second hole in a second rotor forms a second track that extends. The second hole makes contact with the control member that passes through the second track. The first track and the second track slant toward each other in the rotation direction of the first and second rotor.

摘要： The variable valve timing controller controls the valve timing of the intake valve. The variable valve timing controller has a shaft, the stator fixed on the engine and generating the magnetic field around the shaft and rotational phase converter converting the torque applied to the shaft. When the valve timing is in the most delayed timing, the engine can be started. The rotational phase of this timing is called the feasible phase. When the stator stops generating the magnetic field, the load torque arise on the shaft. The rotational phase converter varies the rotational phase into the feasible phase with receiving the load torque from the shaft.

摘要： In a valve timing control device, when a camshaft is retained relative to a timing pulley, a hydraulic piston is applied with a force which moves it in a direction toward an advancing-side hydraulic chamber (i.e., in the direction to vary a valve timing to a delaying side) owing to reaction of the driving torque of the camshaft. This force causes fluid to leak out of the advancing-side hydraulic chamber, and the hydraulic piston is liable to move toward this hydraulic chamber. However, fluid of an amount corresponding to an amount of this leakage is supplied to the advancing-side hydraulic chamber by way of a control valve. Also, discharge of fluid from a delaying-side hydraulic chamber via the control valve is stopped. Thus, the movement of the hydraulic piston toward the advancing-side hydraulic chamber when the hydraulic piston is retained at a desired position is prevented. Therefore, the hydraulic piston can be stably retained at the desired position, and a desired valve timing can be maintained.
