Abstract

To provide for extended true running of the distributor shaft and prevent wear on relatively movable mechanical components within the distributor, such as a shaft and bearings, a centrifugal spark advance/retard mechanism, or the like, the relatively movable parts are included in the lubricating circuit of the engine, for example by being connected to the pressure lubrication system of the engine or located to be exposed to oil mist in the engine compartment and arising upon operation of the engine, so that the relatively movable parts are constantly lubricated by the engine lubricating system.
