AMENDED CLAIMS received by the International Bureau on 30 March 2019 (30.03.2019). 1. (Currently amended) A fluid valve assembly comprising: an outlet base dimensioned to be positioned at least partially through a drain in a fluid tank; a float assembly comprising a moveable float including a lower ballast region at a first end of the moveable float, the moveable float configured to form an at least partially fluid-tight seal at the first end when the moveable float is coupled to the outlet base, and to form a flow opening when the moveable float is at least partially decoupled from the outlet base; a housing positioned within the moveable float, the housing enclosing a suction device coupled to a moveable piston; an actuable diaphragm positioned in the outlet base; a compressed air tube or passageway coupled to one side the actuable diaphragm, the actuable diaphragm configured and arranged to be actuated by compressed air to move the moveable piston; and a sliding air gate configured to automatically open to vent air from a built-in buoyancy cup of the moveable float. 2. (Original) The fluid valve assembly of claim 1, wherein as a result of movement of the moveable piston, the suction device comprises a suction cup configured to be deformed against an inner surface of the housing forming a vacuum chamber, 3. (Original) The fluid valve assembly of claim 1, wherein the seal comprises a coupling of a lower lip of the moveable float and an upper lip of the outlet base, 4. (Original) The fluid valve assembly of claim 1 , further comprising a fluid sensor. 5. (Original) The fluid valve assembly of claim 4, further comprising an air tube or passageway coupled to the housing and fluidly coupling the fluid sensor to the housing. 6. (Currently amended) The fluid valve assembly of claim 1 , wherein the lower ballast region is positioned between an inner wal l and an outer wall of the first end. 7. (Original) The fluid valve assembly of claim 1, further comprising an upper ballast region at a second end of the moveable float, the upper ballast positioned between inner and outer walls of the second end. 8. (Original) The fluid valve assembly of claim 6, wherein the lower ballast region is configured to gain fluid to form a weight ballast when the moveable float is decoupled from the outlet base and the flow opening is present with fluid flowing from the fluid tank through the drain. 9. (Currently amended) The fluid valve assembly of claim 1 , wherein the bui lt-in buoyancy cup comprises an inverted cup element built couple or integrated with the float. 10. (Original) The fluid valve assembly of claim 9, wherein the inverted cup element is configured and arranged to generate buoyancy to lift from fluid flowing from the fluid tank when the flow opening is present. 1 1. (Original) The fluid valve assembly of claim 9, wherein the inverted cup element is configured and arranged to be exposed to atmospheric pressure when the float is not yet exposed to buoyant force. 12. (Original) The fluid valve assembly of claim 9, wherein the inverted cup element includes an air vent. 13. (Currently amended) A fluid valve assembly comprising: an outlet base dimensioned to be positioned at least partially through a drain in a fluid tank; a float assembly including a moveable float, the moveable float configured to form an at least partially fluid-tight seal at a first end when the moveable float is coupled to the outlet base, and to form a flow opening when the moveable float is at least partially decoupled from the outlet base; a housing positioned with the moveable float, the housing enclosing a suction device coupled to a moveable piston; and a sl iding air gate configured to automatically open to vent air from a built-in buoyancy cup of the moveable float. 14. (Original) The fluid valve assembly of claim 13, further comprising an actuable diaphragm positioned in the outlet base. 15 , (Original) The fluid valve assembly of claim 13, further comprising a compressed air tube or passageway coupled to one side the actuable diaphragm, the actuable diaphragm configured and arranged to be actuated by compressed air to move the moveable piston. |
