Abstract:
1. A fluid flow regulator comprising: a first conduit providing a flow passage therethrough from an inlet to an outlet, the first conduit having an aperture therein between the inlet and the outlet; a second conduit extending from the aperture and providing a bypass flow passage thereto; a valve operable within the bypass flow passage and outside the flow passage for movement between a closed position and an open position, wherein fluid flow from the bypass flow passage to the flow passage through the aperture is ceased when the valve is in the closed position, and wherein the valve is hinged to a wall of the second conduit upstream the aperture; a spring carried entirely within the bypass passage, the spring applying a biasing force to the valve so as to bias the valve toward the closed position, wherein the biasing force is applied to the valve at a location offset from an axis of rotation thereof; and an adjustment member carried by the second conduit and operable with the spring, the adjustment member operably moveable toward and away from the valve for modifying the biasing force thereon.
