Abstract:
A fluid flow regulator for regulating flow in tubes of suction or blower systems, havinga regulator body formed by a plurality of body parts with interconnecting first and second body parts which are movable relative to each other from a first position to a second position; and in the first position the plurality of body parts form an inner continuous conduit connectable to a vacuum or blower system to allow substantially only flow through the inner conduit, and in the second position the first and second body parts are relatively positioned to form the inner conduit with a secondary opening feeding thereto allowing fluid to flow into or out of the secondary opening to regulate the flow along the inner conduit;the regulator further including a cage-like guard extending from at least one of the plurality of body parts and substantially surrounding the connection of the first and second body parts and the opening when in at least the second position, the guard having openings sized to prevent finger insertion and sized relative to the size of the secondary opening to readily allow flow of fluid to pass through the opening when in use.
