Abstract: A rocker arm assembly for translating force between an intermediate member in communication with a camshaft of an internal combustion engine and a valve supported in a cylinder head of the engine. The rocker arm assembly includes a tube member and an arm. The tube member has first and second ends, a substantially cylindrical inner surface, and a tapered outer surface. The arm has a body extending between a pad for engaging the valve of the engine, and a socket for engaging the intermediate member of the engine. The body also has a tapered bore disposed between the pad and the socket. The tapered bore of the body of the arm cooperates with the tapered outer surface of the tube member so as to define a lock for constraining the arm to the tube member at a predetermined position between the first end and the second end.

Abstract: A valve gear lubricating device is provided for lubricating a valve gear of an engine including a cam shaft which is rotatable by the engine, and a rocker arm oscillated by a cam disposed on the cam shaft. A slide contact portion is formed on one end of the rocker arm and is slideably contactable with the cam. A hydraulic valve adjuster is mounted on the other end of the rocker arm and is adapted to adjust a valve clearance of the engine. The rocker arm is provided with a mixture passage through which flows a mixture of air and lubricating oil discharged from the hydraulic valve adjuster. A terminal end of the mixture passage opens close to a moving part of the valve gear.

Abstract: An improved rocker arm adjusting nut characterized by an upper collar, a lower flange and an axially elongated body with a substantially cylindrical central section that is provided with knurling, or grooves in the axial direction. The upper collar and knurling deflect oil axially towards the lower flange when used according to its intended purpose with a stamped steel rocker arm, of conventional design. The enlarged mass and surface area of the adjusting nut helps both to dissipate temperature from the pivot ball-rocker arm interface, by conduction, and deflect oil towards the pivot ball-rocker arm interface.

Abstract: A lubricant supply rail is provided for an internal combustion engine to provide an adequate supply of lubricant from the engine lubrication circuit to the bearing surfaces of the rocker arms, the valves and the push rods. The lubricant supply rail of the present invention is configured to provide automatic fluid communication between the cylinder head lubricant outlet port and the lubrication channels contained within the rocker arm support assembly and includes a lubricant supply inlet which communicates directly with the cylinder head and a plurality of transfer bores spaced to communicate directly with each rocker arm support assembly. The lubricant supply rail is preferably formed of nylon or like material and includes a conduit portion sealed at each end by end caps having a configuration which permits effective sealing of the conduit by ultrasonic welding techniques. The conduit portion of the lubricant supply rail has a cross-sectional configuration which permits the rail to be held in sealing engagement with the rocker arm pedestal base. Installation of the lubricant supply rail is accomplished quickly and easily during engine assembly.

Abstract: A valve operating system of an internal combustion engine comprises a rocker arm swingable relative to a rocker arm shaft, and having a first end portion co-operative with an operating cam and a second end portion co-operative with a valve stem. The rocker arm is formed at its central part with a bearing section at which the rocker arm is swingably supported on the rocker arm shaft. The bearing section abuttingly contacts and extends along the outer peripheral surface of the rocker arm shaft. Additionally, the valve operating system is so arranged that engine lubricating oil is supplied under pressure between the rocker arm bearing section and the rocker arm shaft, thereby rendering the valve clearance zero in order to reduce noise generation from the valve operating system.
