The rocker arm is the part responsible for transmitting the movement of the camshaft towards the intake and exhaust valves of the engine, a process that occurs through the direct contact of these parts with the tappets and according to the movement of the shaft.
While the rocker arms have direct contact with the tappet at one of its ends, the other end of this component is coupled to the intake and exhaust valves. This means that, when triggered by the camshaft cam, the rocker arm lowers one of its sides, allowing the valve to be opened in order to let the mix of air and fuel to enter the combustion chamber, this movement occurs for both intake and exhaust valves.
