野生水仙花摘要：An improved variable volume air controller for u in conjunction with a conditioned air distribution system is disclod which compris an insulated lined housing having an inlet, an outlet, and a control asmbly operative to vary the volume of air flowing therethrough. An air flow diffur is also provided being positioned in overlying relationship to the inlet opening which operates to substantially improve air flow distribution over the cross ctional area of the housing whereby the control asmbly may operate to provide improved relatively noi-free modulation of air flow. Additionally, a stop asmbly is provided which cooperates with a portion of the control asmbly to limit movement thereof beyond a true full open position as well as to inhibit air flow induced vibration thereof when the control asmbly is in a full open position.
