ABSTRACT:
An improved flow control irrigation device automatically stops the flow of water to an area when that area has received a predetermined quantity of water and then redirects the water to another area. The device includes a chamber, a carriage assembly, and a two-step valve which is actuated by the carriage assembly. The two-step valve first reduces the static pressure within the chamber and then fully opens an outlet to direct the flow of water to another area. The device also includes internal fluid dampers to protect the device from damage as the carriage assembly and two-step valve are moved from an irrigating position to a bypass position. The irrigation device also includes a pressure release element which facilitates resetting the device to once again deliver water to an area adjacent to the device.
