摘要： An improved control device for intake and/or exhaust valves of an internal combustion engine includes a small circumference portion defined in a drive shaft at a location corresponding to that of an annular member which is eccentrically displaced for changing a rotational phase of the cams. According to this a degree of displacement of the annular member may be increased and control the cams, and thereby the engine valves, may be enhanced. Further, the cam lobe of each cam is formed such that side portions thereof are asymmetrical with respect to a center line of the cam for favorably affecting valve opening and closing timings. In addition, an improved lubricating arrangement for enhancing smooth operation and improved engine performance.

A rocker arm is supported by a hydraulic lash adjuster or a rocker shaft for pivotal motion and has a sub-rocker shaft and a pin. The rocker arm is drivingly engages the low lift cam lobe. A free cam follower is supported by the sub-rocker shaft and drivingly engages the high lift cam lobe. A latch lever supported by the pin has a latch position wherein one end portion of the latch lever is in locking engagement with the free cam follower and a latch release position wherein the one end portion of the latch lever is out of engagement with the free cam follower. A hydraulic piston received in bore is in driving engagement with the opposite end portion of the latch lever to urge the latch lever against a latch lever release spring towards the latch position thereof. Hydraulic fluid communication between the bore and a hydraulic fluid passage of the cylinder head structure is established through the hydraulic lash adjuster or the rocker shaft.

摘要： A control device controls intake and exhaust valves of an internal combustion engine. The device comprises a first flange provided by a cam shaft of the engine, which flange has a first radially extending elongate slit. A second flange faces the first flange with a certain clearance therebetween and is secured to a drive shaft to rotate therewith. The second flange has a second radially extending elongate slit. An annular member is disposed within the clearance and rotatable about an axis of the drive shaft. First and second pins are rotatably held by opposed sides of the annular member respectively. These pins are positioned at diametrically opposed positions with respect to a center of the annular member and slidably engaged with the first and second elongate slits respectively. A drive mechanism is employed for pivoting the annular member about a pivot axis eccentric to the axis of the drive shaft in accordance with an operating condition of the engine.

摘要： A valve timing control system includes of a cylindrical sprocket driven through a timing chain by a crankshaft of the engine. An arm is fixed to one end section of the camshaft and located inside the sprocket in a manner to extend generally diametrically. First and second plungers are slidably disposed respectively in first and second cylindrical bores formed in the sprocket. A hydraulic pressure chamber is defined between the bottom portion of each plunger and the bottom wall of the cylindrical bore so as to be supplied with a hydraulic pressure from a hydraulic pressure source. Each plunger is projectable toward the arm upon supply of the hydraulic pressure to the corresponding hydraulic pressure chamber thereby to cause the arm to rotate relative to the sprocket. Projections of the first and second plungers induce the rotational movements of the arm in opposite directions relative to the sprocket, respectively. The rotational movements of the arm cause the camshaft to undergo relative rotation which advances or retards the valve timing of the intake and/or exhaust valves.
