Openings through the fixed plate and the openings through the sliding plate can each make up about 70% of the active area of each plate. The slide plate can be slid to a position where its webbings divide each fixed plate opening into two orifices for air flow. The air flow can be controlled by selecting the slide position of the webbings from a most restrictive position in which the webbings are in the middle of fixed plate openings, through a range of positions where the orifice on one side of the webbing is larger than the orifice on the other side of the webbing, to a maximally opened position where the webbing on the slide plate overlies the webbing on the fixed plate. | 05-21-2015 |
