Tappets are important components in the valve train of an internal combustion engine and transmit the movement of the camshaft to the valves. They ensure that the intake and exhaust valves open and close at the correct time, thus precisely controlling the gas exchange in the engine.

Depending on the engine design, mechanical or hydraulic tappets are used. Hydraulic tappets, also called hydro tappets, automatically compensate for valve clearance and ensure smooth engine operation. They are supplied with oil via the engine's oil circuit, which automatically compensates for play in the valve train. Mechanical tappets are frequently used in high-performance engines and require precise valve clearance adjustment.

Tappets are subjected to high mechanical stresses because they are in continuous contact with the camshaft. Wear can lead to rattling noises in the engine, rough running, or loss of power. High-quality materials and precise manufacturing are therefore crucial for a long service life and reliable valve train function.
