Abstract
Abstract A distributor for a spark ignition internal combustion engine is driven via a drive spindle 3 which is held via a resilient bush 4 in a drilling in the end of a camshaft 1 of the engine which operates the usual valve gear. Advance and retard are performed electronically. The resilient bush protects the drive spindle 3 and rotor from vibrations of the camshaft.
