摘要： A valve timing control device for an internal combustion engine, comprises a drive rotary member rotated by a crankshaft of the engine, a driven rotary member to rotate a camshaft of the engine upon rotation of the drive rotary member; a rotational phase control mechanism having an intermediate rotary member rotated relative to the drive and driven rotary members to cause relative rotation between the drive and driven rotary members and an braking mechanism having a hysteresis brake that generates a braking force to cause the intermediate rotary member to rotate relative to the drive and driven rotary members.

摘要： In a valve timing control system, an intermediate rotator is rotated with respect to a driving plate and a lever shaft to make radial displacement of a ball engaged with a spiral slot of the intermediate rotator along a radial slot. The radial displacement is converted into relative rotation of the driving plate and the lever shaft through a link. A bottomed cylindrical guide member which is rotatably supported by a front end of the link has a base engaged with the spiral slot. The ball engaged with the spiral slot, a retainer for supporting the back of the ball, and a coil spring for biasing the ball through the retainer are accommodated in a hold hole of the guide member. Disengagement of the ball from the spiral slot is prevented by an abutment of an end face of the retainer and a bottom wall of the hold hole.

摘要： A drive rotation member is driven by a crankshaft of the engine, and a driven rotation member is rotatable relative to the drive rotation member and secured to a cam shaft of the engine. An electric motor is arranged to rotate together with the drive rotation member and produces a dynamic power when fed with an electric current through brushes. A hollow control shaft is rotatable relative to the drive rotation member and forces the driven rotation member to rotate relative to the drive rotation member when rotated by the power of the electric motor. A bearing device is arranged between the driven rotation member and the hollow control shaft for smoothing a relative rotation therebetween. The bearing device includes a plurality of rollers. A lubrication oil feeding structure is provided for causing the rollers of the bearing device to be submerged in a lubrication oil at least when the engine is in operation.
