<p>An aircraft pneumatic de-icing system distributor valve for controlling the inflation and deflation of pneumatic de-icer boots. Two independent pistons (13) are configured with opposing faces and arranged to move along the same axis causing their respective annulus of holes to become covered from or exposed to a pneumatic supply and thus directing air from a concentric inlet manifold (7) to one or more concentric outlet manifolds (10). A dual jet pump assembly (8) is attached to the valve body and configured so as to receive air from the inlet manifold and evacuate air from the outlet manifolds.</p> |
