LUBRICATING OIL SUPPLY RAIL

摘要

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.
