A liquid dispensing apparatus comprising two vessels (12, 14) each situated to be gravitationally displaceable between a high elevation liquid charging location and a low elevation liquid discharging location. The vessels (12, 14) are interlinked by which the downward movement of the charged vessel causes the return of the discharged vessel to the charging location, and also causes the displacement of the apparatus. The apparatus is an automatic irrigation apparatus in which two reservoirs (12, 14) are mounted on a common base (16), pivotally mounted on a central supporting member (18) enabling the reservoirs to pivot between fluid dispensing and fluid receiving positions. A rotation mechanism (24) is actuated by the pivoting motion, causing the apparatus to rotate about a central supporting member (18). Alternatively the two fluid reservoirs (12, 14) are mounted on a common base and are connected by a suspended cable on pulleys, enabling the reservoirs to move vertically and alternatively between fluid dispensing and fluid receiving position. |
