Introduction
The rocker assembly is an indirect valve actuating
system consisting of rocker arms and a shaft.
The rocker arm is an oscillating lever that conveys
radial movement from the cam lobe into linear
movement at the poppet valve to open it. One end is
raised and lowered by a rotating lobe of the camshaft
via a tappet and push rod while the other end acts
on the bridge piece which is connected to the valve
stem.
