1. A method for delivering an air blast, comprising;
a. delivering pressurized air against a movable closure member in an enclosed housing to move the closure member contactingly closingly against an aperture in the housing while permitting the pressurized air to fill the housing; and b. relieving pressure of air against the closure member thereby permitting the closure member to move away from the aperture, resulting in escape of pressurized air from the housing via the aperture.
