Working of Valve Spring

The purpose of the valve spring is to exert a force on the rocker arm in order to maintain contact between the follower and cam at the other end. During the suction stroke, the initial spring force keeps the valve closed against negative pressure inside the cylinder. The total force acting on the spring of the exhaust valve consists of two factors, the initial spring force and force required to lift the valve.
