Abstract:
A lubricant supply rail (2) for providing an adequate supply of lubricant from the lubrication circuit of an IC engine to bearing surfaces of the rocker arms, valves (8 and 10) and push rods, is configurated to provide automatic fluid communication between the cylinder head lubricant outlet port (26) and lubrication channels contained within the rocker arm support assemblies (6) and includes a lubricant supply inlet which communicates directly with the cylinder head (4) and a plurality of transfer bores (54) spaced to communicate directly with each rocker arm support assembly (6). The lubricant supply rail (2) is formed of nylon and includes a conduit portion sealed at each end by caps configured to seal the conduit by ultrasonic welding. The conduit portion has a cross-sectional configuration which permits the rail (2) to be held in sealing engagement with the rocker arm pedestal base <18).
