Do you need adapter in order to inflate air

It depends on the type of pump that you use. Many small hand pumps, or air compressors will need an adapter. I have a bicycle pump that does both types of tubes without the need for an adapter .

How do these adaptors trigger the air release in the Schraeder tire inflator? Does it rely on the Presta valve stem?

When I screw the Presta adapters onto the valve stem, it begins to release air. You have to turn the adapter counterclockwise a couple of times so air from the pump will flow in.
