Abstract: A natural ventilator is herein disclosed that is free of moving parts, wind-activated, rain-proof, and free of dust or smog infiltration. It is not only suitable to be a standalone natural ventilator, but is also advantageous to be used as an enhanced exhaust exit in a forced-air ventilation system, for such enclosed spaces or objects as buildings and vehicles needing air relief. The ventilator assembly has rainwater-proof shapes or fixtures that serve to defend the vent system, and the interior space being vented, against rainwater invasion, even if raindrop trajectory becomes highly oblique from vertical as driven by strong winds. It also includes shapes or fixtures to prevent fume condensation from drifting outward and staining the exterior of a building or vehicle, or the like, that is being vented.

Abstract: This invention provides a natural ventilator that is free of moving parts, wind-activated, rain-proof, and not only suitable to be a standalone natural ventilator but also advantageous to be used as an enhanced exhaust exit in a forced-air ventilation system. It can also be used as a suction generator that supplies so-called suction or negative pressure to help stabilize such building components as roof membranes by channeling the low pressure to its underneath to balance the wind uplift above.The ventilator includes a hollow base body to be secured onto an exterior surface of such enclosed objects as a building or vehicle and having a convex upper face, and a hollow raised body being supported and secured on the base body with elongated hollow members and having a convex lower face towards the base body. The elongated hollow members establish conduits that channel the internal spaces of the hollow base and raised bodies. A free space is formed between the convex faces of the base and raised bodies. Each of the said convex faces has an opening, at or near their centers and substantially facing each other. The said convex faces of the base and raised bodies are configured in such a way that the free space between the convex faces is generally narrower near the openings than away from them. This forms a first contracting and then expanding path for airflow to approach from any direction and to pass through the free space between the said convex faces, providing a venturi mechanism. The device thus creates low pressure in the free space near the openings and hence a suction effect therein, which can be readily communicated to any interior space of a building or vehicle needing air relief or suction and to be properly connected with the hollow base body.A series of enhanced rainwater-proof designs are illustrated to exemplify methods of defending the system against rainwater invasion, even if raindrop trajectory becomes highly oblique from vertical as driven by strong winds.

Abstract: This invention provides a natural ventilator that is free of moving parts, wind-activated, rain-proof, and not only suitable to be a standalone natural ventilator but also advantageous to be used as an enhanced exhaust exit in a forced-air ventilation system.The ventilator includes a base plate to be secured onto a substantially vertical exterior surface of such enclosed objects as a building or vehicle, a substantially horizontal tube connected to at least one opening substantially centered on the base plate, and a raised body being supported and secured on the base plate with elongated members and having a convex face towards the opening on the base plate. A free space is formed between the base plate and the convex face of the raised body. The convex face of the raised body is configured in such a way that the free space between the convex face and base plate is generally narrower near the opening on the base plate than away from the opening. This forms a first contracting and then expanding path for airflow to approach from any direction and to pass through the free space along the base plate, providing a venturi mechanism. The device thus creates a low air pressure in the free space near the opening and hence a suction effect therein, and communicates the suction effect to any interior space of a building or vehicle needing air relief or suction, through the substantially horizontal tube and any connecting conduit if needed. Several example designs for the tube illustrate methods to prevent rainwater from infiltrating into the interior space that is being vented and unsightly fume condensation from drifting outwards to the building or vehicle exterior. Such devices, as configured according to the spirit of this invention, provide for a simple suction ventilator that effectively prevents rainwater from infiltrating into the interior, even if raindrop trajectory becomes highly oblique from vertical as driven by strong winds. It also substantially stops unsightly fume condensation from drifting outwards to the building or vehicle exterior.
