Abstract
A fluid valve is provided including an inner shell and an outer shell. The inner shell includes a sidewall having a first opening and an interior surface defining an inner chamber. The outer shell includes a sidewall having a second opening and an exterior surface defining an outer chamber. The inner shell is positioned within the outer shell and the inner shell is movable relative to the outer chamber between a first position and a second position by a change in fluid conditions of a fluid supplied to the fluid valve. The first opening and the second opening overlap to define a passageway extending from the interior surface of the inner shell to the exterior surface of the outer shell. Relative movement of the inner shell from the first position toward the second position reduces a cross-sectional area of the passageway.
