ABSTRACT:
There is disclosed an irrigation device of the type comprising a hose which is adapted to be connected at one end to a water supply point and at the other end to a spraying device, a drum which is rotatable to coil the hose during an irrigation process and a turbine to be connected to the water supply point and attached to said one end of the hose and adapted to actuate the drum to coil up the hose at a speed dependent upon the pressure of water passing from the supply point to the hose. Known irrigation devices of this type have suffered from the drawback that it is difficult to maintain the turbine speed within a narrow desired range therefor. The irrigation device of the invention is additionally provided with a bypass pipe equipped with a flow control valve bypassing the turbine and associated means for controlling the speed at which the hose is being coiled onto the drum.
