The Function of Engine Valve Tappet

 

Valve lifters, also known as tappets, play a critical role in the engine's valve train. Their primary function is to transmit the force from the camshaft to the push rod or directly to the valve stem, enabling the push rod or valve to overcome the force of the valve spring and move. Additionally, they bear the lateral forces exerted by the rotating camshaft.

 

Valve tappets are installed in guide holes that are bored into the engine block or cylinder head. They are commonly made from materials such as nickel-chromium alloy cast iron or chilled alloy cast iron, which offer the necessary strength and wear resistance to withstand the high stresses and temperatures present in the engine.

 

These materials are selected for their durability and ability to maintain dimensional stability under the extreme conditions found within an engine, ensuring reliable operation over the engine's lifetime.
