Abstract
A rotary nozzle device is described. The device includes plural rotatable hollow links which are mutually passable through, a pump for feeding a pressurized fluid into the hollow links, and at least one fluid injection port in at least one hollow link of the nozzle. Moreover, the fluid is injected from the injection port while the hollow link is rotated by the force of the fluid pressurized by the pump, and the motion of the injection port is set in chaotic state by adjusting a structural characteristic of the nozzle.
