Inlet and exhaust valve seats become damaged
during the operation and from time to time they
have to be reconditioned by grinding-in. This is
required much more often in the case of the
exhaust valves because they operate at higher
temperatures and because the gases flowing
through may contain particles of carbon matter.
These occasionally get trapped under the valve
seat and cause pitting. The life of an exhaust
valve between reconditioning can be extended if
the thermal loads to which it is subjected can be
evenly distributed around the valve. This is
accomplished by rotating the valves slowly as the
engine is working. The rotator which carries out
this movement indexes the valve round a small
amount every time it is operated by the rocker
gear. In more recent designs, the exhaust valves
are rotated by the vanes fitted to the stem and
driven by the gases expelled from the cylinder.
