Abstract: An apparatus is presented for autonomously controlling fluid flow in a subterranean well, the fluid having a density which changes over time. An embodiment of the apparatus has a vortex chamber, a vortex outlet, and first and second inlets into the vortex chamber. Flow into the inlets is directed by a fluid control system which has a control passageway for directing fluid flow as it exits a primary passageway. A movable fluid diverter positioned in the control passageway moves in response to change in fluid density to restrict fluid flow through the control passageway. When fluid flow through the control passageway is unrestricted, fluid from the control passageway directs fluid exiting the primary passageway toward a selected vortex inlet. When flow through the control passageway is unrestricted, flow from the primary passageway is directed into the other vortex inlet.

Abstract: Vacuum release systems that allow rapid, uninterrupted flow of a liquid through a first opening in a container when the container is inverted are disclosed. The vacuum release systems include a hole punch and can be secured to the outer surface of the container. When the liquid-filled container is inverted, pressure is applied to the hole punch to form a second opening in the side of the container. The second opening releases the vacuum by allowing air to flow into the container, which, in turn, allows rapid, uninterrupted flow of the liquid through the first opening in the container.

Abstract: A fuel cutoff valve comprises a casing having a primary valve chamber and a secondary valve chamber, a primary valve mechanism housed in the primary valve chamber, and a secondary valve mechanism housed in the secondary valve chamber. The casing has a first communication path that connects the inside of the fuel tank and the primary valve chamber, and a second communication path that connects the primary valve chamber and the secondary valve chamber, due to the differential pressure between the tank internal pressure and the primary valve chamber, by the fuel in the fuel tank flowing into the primary valve chamber through the first communication path, a connection conduit is closed by the primary valve mechanism. When the fuel level inside the fuel tank reaches a second fuel level, the second communication path is closed by the rising of the secondary valve mechanism.
