Air Injection Control Valve: Description and Operation

Pneumatic Switch-over Valve

A pneumatic switchover valve is fitted between the air pump and exhaust valve. It is closed when the secondary air system is inactive and thereby
prevents the induction of additional air as a result of flow conditions.
