Valve Spring Retainer Lock

Valve spring retainer locks, also known as valve keepers or valve locks, are small metal components used in internal combustion engines. They are designed to secure the valve spring retainers in place, preventing them from coming loose during engine operation.

Valve spring retainers are responsible for holding the valve springs in position, ensuring proper valve operation and maintaining valve-to-seat contact. The valve spring retainer locks are inserted into the valve stem groove and hold the valve spring retainer in place, preventing it from moving or rotating.

These locks are typically made of hardened steel or other durable materials to withstand the high pressures and temperatures within the engine. They come in various shapes and designs, depending on the specific engine and valve configuration.

Valve spring retainer locks are crucial components in the valve train system of an engine, as they help maintain proper valve timing and prevent valve float, which can lead to engine damage or failure.
