ABSTRACT:
A fluid control apparatus is for controlling water supply to a potted plant and has a main valve responsive to weight of the potted plant. The apparatus comprises a main body to support the load of the plant, a valve body adapted to be suspended from a support, and a resilient member cooperating with the main body and valve body to be responsive to load of the plant acting on the main body. A delivery conduit receives water under relatively low pressure and flow of the water is controlled by the main valve. The main valve has a first valve portion, e.g. a valve seat on the valve body, and a second valve portion, e.g. a poppet valve. A valve adjuster, a critical valve area, and water pressure determine actuation of the main valve. Preferably, the main valve closes when load acting on the apparatus is a pre-determined load reflecting weight of the fully watered plant, and as the plant becomes lighter, opening of the valve is delayed to ensure delivery of a relatively large amount of water.
