摘要： A camshaft phase changing device has a pair of axially-spaced annular front and rear gears disposed and engaged between co-axial drive and driven members. An annular piston is mounted to the annular rear gear by a plurality of piston pins. The piston pins pass through openings of the rear gear toward the front gear. Each of the openings is dimensioned to provide a clearance around the corresponding one of the piston pins and keep the rear gear out of contact with outer surface of the corresponding piston pin.

摘要： A valve timing adjusting system includes mutually parallel axial fluid paths both formed about a fastening bolt which engages with an axial bore formed at the end of a camshaft. One of the axial paths if formed through the fastening bolt and the other axial path is formed between the outer periphery of the fastening bolt and the inner periphery of the axial bore of the camshaft. This avoids necessity of formation of axial fluid path through the camshaft and thus redudes mashing step in production line to lead lower cost.
摘要翻译：气门正时调整系统包括相互平行的轴向流体路径，两者均围绕紧固螺栓形成，紧固螺栓与形成在凸轮轴端部处的轴向孔接合。如果通过紧固螺栓和另一个轴向路径形成的一个轴向路径形成在紧固螺栓的外周和凸轮轴的轴向孔的内周之间。这避免了通过凸轮轴形成轴向流体路径的必要性，从而减少生产线中的糖化步骤以降低成本。

摘要： An intake- and/or exhaust-valve timing control system for an internal combustion engine comprises a timing belt pulley having a driven connection with an engine crankshaft, a camshaft journaled by a bearing member mounted on a cylinder head and receiving torque transmitted from the timing belt pulley, a ring gear mechanism for adjusting a relative phase angle between the timing belt pulley and the camshaft. The valve timing control system includes a first hydraulic circuit provided for drivingly controlling the ring gear mechanism via fluid pressure depending upon the operating state of the engine and a second hydraulic circuit provided for lubricating frictional surfaces between the bearing member and the camshaft. The first and second hydraulic circuits are separated from each other. The valve timing control system includes a directional control valve connected to the first hydraulic circuit for switching the direction of working fluid flowing through the first hydraulic circuit.

摘要： A variable intake- and/or exhaust-valve timing control system for an internal combustion engine comprises a cam sprocket having a driven connection with an engine crankshaft, a camshaft, a ring gear provided between the camshaft and the cam sprocket for adjusting a relative phase angle between the cam sprocket and the camshaft, and a ring gear drive mechanism for drivingly controlling the ring gear via fluid pressure created by an engine oil pump, depending upon the operating state of the engine. The drive mechanism includes a subsidiary oil pump for supplying a fluid pressure greater than a designated pressure level to the ring gear, during low engine speed and high engine load.

摘要： In a valve operating apparatus, torque is transmitted from an eccentric drive cam attached to a drive shaft through a multinodular-link motion-transmission mechanism including a link arm, a rocker arm, and a link rod to a rockable cam to cause an engine valve to open and close. Also provided is a control cam whose geometric center is displaced from a control shaft. By way of eccentric rotary motion of the control cam, a valve lift of the engine valve is variably controlled. Lubricating oil supplied from an oil passage formed in the drive shaft via a first communicating passage formed in the drive cam into a clearance between the link arm and the drive cam, is forcibly fed via a second communicating passage into a pivotally linked portion between the link arm and the rocker arm by oscillatory pumping action created by eccentric rotary motion of the drive cam.
