Roland, you are correct, when the engine is cold the valve allows the air flow to come from the hose that connects to the exhaust manifold. When the engine warms up, it closes that path way off and allows cool air in to the engine. This process allows the engine to warm up faster and prevents icing in the intake manifold.
