The main role of cam shaft is to transmit the power push rods-rocker arm-engine valves. The cam shaft powered by crankshaft by means of gears.
Now a day all engines valves are operated by cam shaft directly with out any push rods and rocker arms.

Power from main engine shaft is taken by the cam during running conditions. And the cam will transfer this power to the rocker arm because of its point contact. And finally this power will transfer to valve through its stem.

But in some engine the cam is directly operate the valve. There is no rocker arm. A seem is placed between valve stem and cam.
This seem is calibrated.

Nowadays, valves are directly controlled by cam shaft. Rocker arm also needs a push rod to control the valves. That why we don't go for the rocker arm.

In pushrod engine, rocker arm transmits power to the valve. But in some of the engines (OHC, DOHC) camshaft directly transmits power to the valves.

Camshaft helps the the valves to inlet and outlet of combusted air, some may possess pulleys drives and some may possess directly through chain.

Rocker is the link which is placed between cams and the valves. Due to the motion of cams the rocker arm moves then the value gets motion.

This is happening only the engine having overhead valve mechanism, and now most of the modern vehicle having overhead valve mechanism.

Rocker is the one of the main parts of engine neelesh what you know about automobile you are very weak in this section.

But most of the engine the power from camshaft is transmitted through camshaft pulley belt drives to valves.
