Abstract
A disclosed system may add different irrigation timing intervals than those of a master flow irrigation system. Electronic timing systems are not used. Native water pressure flowing internally into the system to move components and otherwise control flow ports is used to control timing. A main fluid intake may accept fluid to pressurize and motivate a diaphragm. The diaphragm houses a ratchet flexure finger which may tangentially engage and rotate a gear spindle which is rotationally coupled to and houses one or multiple cams. A 2-way valve is in contact with one of the cams tangentially and centrically via a valve plunger. The cam(s) have lobe(s) with the peak of the profile being the nose and lower profile base circles. As the cam is rotated, it engages with the valve plunger at the nose or base circle, thus opening and closing the 2-way valve and allowing or stopping flow.
