Abstract
An exhaust duct connector takes the form of a Y-shaped passage. Both of the branches of the Y are adapted to receive ends of upstream exhaust ducts and a leg of the Y is adapted to receive one end of a downstream exhaust duct. A substantially plate-like partition is positioned at the junction of the Y parallel to the single leg. The partition includes a plurality of holes through which exhaust can pass. The partition may include an outer partition member having a plurality of holes and an inner partition having numerous extremely small holes covered by the outer partition member. The partition may contact the adjacent inside wall of the Y-shaped passage, or be spaced from the adjacent inside wall of the Y-shaped passage. The partition may take the form of an airfoil.
