It actually only opens at low throttle angles. It opens a path from the pressure side of the blower to the intake side of the blower - essentially a bypass that greatly reduces the power required to turn the assembly. It's a fuel economy saving device that allows the engine to revert to traditional "vacuum mode" when not under load.
