 Valve rotators are used on diesel and gas engines in wide variety of applications. Each time a valve operates, the valve rotator turns the valve slightly.

 Ball & Spring
These work by using a series of spring-loaded ball and ramp assemblies. Again the effect is to rotate the supported Valve Spring.

 Garter Springs
These work by the action of the internal spring on the two main rings. The effect causes a small rotation of ring supporting the Valve Spring.

These are used on large diesel and gas engines. Each time a valve closes, the valve rotator turns the valve slightly, and allows the inlet and exhaust valves to be heated and cooled symmetrically. It also prevents valves sticking due to uneven carbon build-up, or wear on the valve seat.
