ABSTRACT:
An improved trickle irrigation unit includes a selector dial for controlling water flow through a plurality of outlet ports. The trickle unit comprises a valve housing having a water inlet port opening into one side of a pressure chamber, the other side of which is defined by a plurality of recessed flow patterns each leading to a respective one of the outlet ports. A resilient valve flap within the pressure chamber is hydraulically seated over the flow pattern and includes an array of flow passages alignable with selected flow patterns to permit water flow thereinto from the pressure chamber, with the flap deforming into the selected flow patterns for pressure-responsive flow control of water to the associated outlet ports. The valve flap is rotatably carried by the selector dial for movement to different set positions to alter the number of flow patterns aligned with flap flow passages thereby correspondingly altering the number of outlet ports in flow communication with the pressure chamber.
