Internal combustion engine rocker arm arrangement having a readily replaceable plate spring

摘要

A plate spring is formed to have a "spider-like" configuration with pairs of bent "spider leg-like" flexible fingers. The spring is fixed to the top of a rocker arm shaft mounting bracket so that each pair of fingers straddles the rocker arm shaft and biasingly contacts a lateral surface of a rocker arm pivotally mounted on said shaft. The fingers have a length adequate to allow for mass production tolerances while simultaneously biasing the rocker arm uniformly along the rocker arm shaft preventing any unwanted uneven wearing of the shaft or rocker arm. The spring may be replaced simply by removing a single bolt.
