Valve Seat Retainer

A valve seat retainer is a component used in internal combustion engines to secure the valve seat in the cylinder head. It is typically made of metal and is designed to hold the valve seat in place during the engine's operation.

The valve seat retainer is installed on top of the valve seat, which is a machined recess in the cylinder head where the valve sits. It helps to ensure proper alignment and stability of the valve seat, preventing it from moving or becoming dislodged during the engine's operation.

Valve seat retainers are commonly used in engines with overhead camshafts, where the camshaft is located above the cylinder head. In these engines, the valve seat retainer is positioned between the valve seat and the camshaft, providing support and stability to the valve seat.

Overall, valve seat retainers play a crucial role in maintaining the integrity and performance of the engine's valve system. They help to ensure proper sealing and combustion, as well as prevent any potential damage or failure of the valve seat.
