A rocker arm is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the valve to open it. One end is raised and lowered by a rotating lobe of the camshaft. While the other end acts on the valve stem. When the camshaft lobe raises the outside of the arm, the inside presses down on the valve stem, opening the valve. When the outside of the arm is permitted to return due to the camshafts rotation, the inside rises, allowing the valve spring to close the valve.
