Abstract

A rocker arm for a type III valve train assembly for an internal combustion engine includes: a roller follower for following a cam in use; a roller axle about which the roller follower rotates in use; a biasing means holder, the biasing means holder being connected to the roller axle for sliding movement relative to the roller axle over a fixed distance, the biasing means holder contacting a reaction component in use; and a biasing means arranged to bias the biasing means holder away from the roller axle. The rocker arm is arranged such that, in use, sliding movement of the biasing means holder relative to the roller axle when the biasing means holder contacts the reaction component when a lift profile of the cam engages the roller follower causes the biasing means to compress and thereby to urge the roller follower into contact with the cam.
