摘要： A valve timing adjustment device for promptly switching a rotational phase includes a guide rotary body having a guide passage containing a movable body. The guide passage includes a variable radial dimension relative to a rotational centerline. The guide rotary body rotates relative to a driving rotary body and guides the movable body in the guide passage. A phase change mechanism changes the rotational phase of a driven shaft relative to a drive shaft according to the position of the movable body in the guide passage. The guide passage has a gradually decreasing region and a gradually increasing region. The gradually decreasing region slants toward an axis of the guide rotary body. The gradually increasing region slants relative toward the axis of the guide rotary body. The gradually decreasing region and the gradually increasing region are connected.

摘要： An internal planetary gear mechanism reduces a load applied to tooth surfaces of an external gear and an internal gear, a sliding portion such as a bearing and the like. By setting the amount of eccentricity α of an eccentric part to be larger than a theoretical value, a distance between the center of the external gear and the center of the internal gear is increased to allow the reduction of a loss in the bearing and on the tooth surfaces of the gears, and a mesh zone between the internal gear and the external gear can be reduced to decrease a part at a large pressure angle, thereby reducing a loss generated by a large pressure angle. As a result of reduction in the mesh zone between the external gear and the internal gear, rolling contact of the gears is maintained.

摘要： An effective range of urging force of an assist spring is between a maximum retarded phase and a predetermined phase of a camshaft, a vane rotor and vanes. The predetermined phase is equal to an intermediate locking phase of the camshaft, the rotor and the vanes+10 degree CA. Even when oil pressure supplied to each advancing chamber is reduced at the time of engine stop, the camshaft, the rotor and the vanes can be advanced to or beyond the intermediate phase by the spring. Furthermore, at the time of engine start, the rotor and the vanes are positioned near the intermediate phase, so that reaction force of the spring is very small, allowing easy movement of the rotor with drive torque of the camshaft toward a retard side. Thus, the rotor can be locked at the intermediate phase by a lock pin.
