a chamber inlet configured to permit air outside the housing to enter the housing;
a flow path defined between the chamber inlet and the chamber outlet;
a restrictor member positioned in the flow path, the restrictor member being moveable between a closed position, where a flow of air along the flow path is restricted, and an open position, where the flow of air along the flow path is less restricted;
a vane in fluid communication with the flow path, the vane being operatively connected to the restrictor member and configured to reciprocate between a first position and a second position in response to a flow of air along the flow path; and,
a one-way valve associated with one of the chamber inlet or the chamber outlet, the one-way valve being configured to close one of the chamber inlet or the chamber outlet until a threshold pressure is obtained;
