Rocker Vs Lifter at Joanne Angelo blog

Rocker Vs Lifter. Sohc are higher performance and lighter (and so typically have a higher rev range) than underhead cams with lifters. The rocker arms open and close the engine’s valves when the camshaft rotates to work the lifters, which act on a number of pushrods. Roller cams, roller lifters and roller rockers each provide value to a performance engine builder. Lifters bridge the camshaft lobes and the rocker arms, ensuring precise timing and smooth operation of the engine’s intake and exhaust. The basic function of a valve lifter is pretty simple. Whereas the use of hydraulic lifters and/or adjust­able rocker arms allow some leeway regarding length, pushrod length is especially critical when using solid lifters and/or nonadjustable. Valve lash is the gap between the tip of the valve and the rocker arm when the lifter is positioned on the base circle of the camshaft. It sits on the camshaft and transfers the motions of the cam lobe up through the pushrods and rockers to open and close the valves. Such a configuration is an ohc (overhead cam) configuration.
