Abstract
The irrigation unit has a propelling tube rotatable about a column, with a torsional brake acting between them. Deflectors for interfering with the jet are arranged at the front of the tube. A rapid return deflector is arranged at the end of a lever below the propelling tube, which rises and lowers for reversal of the irrigator motion. The rotatable tube is automatically braked by a unit which is self adjusting according to the water pressure. The swing period of the mobile nose is adjustable, a double acting deflector being contacted by the water jet to move the nose and arrest the swing before collision with the propelling tube. The irrigator can be set to cover a complete circle of ground or just a segment. The unit can operate uniformly from high water pressures. The rotational speed of operation is adjustable.
