Title: Rotary jet irrigation equipment - has head incorporating jet driven by maltese cross mechanism to increase water coverage
IPC: B05B3/04
Filed: 1979-05-30
Abstract: The irrigation system has a jet head rotated at a given speed to ensure adequate coverage, but not too fast to reduce the efficiency of the jet. The rate of flow of the jet is varied regularly for each amount of rotary movement of the jet.
