<P> The hydraulic lifter , situated between the camshaft and each engine 's valve , is a hollow steel cylinder encasing an internal piston . This piston is held at the outer limit of its travel with a strong spring . The lobed camshaft rhythmically presses against the lifter , which transmits the motion to the engine valve one of two ways : </P>
