ABSTRACT:
A self-propelled irrigation apparatus has a main pressurized irrigation liquid distribution pipe with its inner end pivotally supported at a central supply pipe and a plurality of radially extending distribution pipe sections which have swinging connections with each other, a mobile support at the outer end of a section, a liquid reaction spray motor for driving each mobile support, a diaphragm-operated "on-off" motor control valve connecting the motor to the distribution pipe, and a pilot valve selectively connecting a pressure control chamber at one side of the control valve diaphragm with either the pressurized irrigation liquid in the pipe or with a pressure relief opening in response to predetermined relative swinging movement of the pipe sections. The apparatus also has one or more controllable irrigation sprinkler units connected to the distribution pipe by a separate diaphragm operated "on-off" sprinkler control valve at a location spaced from the reaction motor, and the sprinkler control valve has a similar pressure control chamber connected to the same pilot valve for simultaneous "on" or "off" control of the reaction motor and sprinkler unit.
