Abstract: A drive rotation member is rotated about a given axis by a crankshaft of the engine, and a driven rotation member is rotated about the given axis together with a camshaft of the engine. A relative rotation angle control mechanism is arranged through which the drive and driven rotation members are coaxially connected. The relative rotation angle control mechanism has a movable control member which, when applied with an operation force from an actuation device, varies a relative rotation angle between the drive and driven rotation members. The actuation device comprises a first electromagnetic brake which applies an operation force to the movable control member to cause a rotation of the driven rotation member to be shifted in one of advancing and retarding directions with respect to a rotation of the drive rotation member, and a second electromagnetic brake which applies an operation force to the movable control member to cause the rotation of the driven rotation member to be shifted in the other of the advancing and retarding directions with respect to the rotation of the drive rotation member.

Abstract: A relative rotation angle control mechanism of a valve timing control device comprises a radial guide provided by one of drive and driven rotation members which are rotatable about a given axis. A movable control member is guided by the radial guide in a manner to move in a radial direction with respect to the given axis. A link links the movable control member to a given portion of the other of the drive and driven members. The given portion is positioned away from the given axis in a radial direction. An intermediate rotation member is rotatable about the given axis relative to both the drive and driven rotation members. A spiral guide is provided by the intermediate rotation member to guide the movement of the movable control member, so that rotation of the intermediate rotation member relative to the radial guide induces a radial movement of the movable control member. A sliding resistance reducing structure is further arranged between the movable control member and the intermediate rotation member to reduce a sliding resistance produced when the movable control member is moved.

The rotary member has a pair of radially extending portions, on which a pair of gears are rotatably supported. The sprocket has an internal toothed circumference which is engageable with the gears to cause the gears to rotate in accordance with rotation of the sprocket for causing relative angular displacement of the rotary member to the sprocket. The valve timing control system further includes a pair of stopper pins for regulating relative angular displacement of the intermediate rotary member to the sprocket within a predetermined maximum range, and a clutch mechanism for restricting rotation of the gears. The clutch mechanism is controlled in accordance with a current engine running condition to be associated with the stopper pins for restricting relative angular displacement of the rotary member to the sprocket.
