NOZZLE FOR JETTING SELF-VIBRATORY FLUID STREAM EXHIBITING HIGH CLEANING EFFICIENCY BY VARYING THE SHAPE OF OUTPUT PORT.

摘要

The nozzle for jetting self-vibratory fluid stream, comprises a main nozzle for forming a jet stream, side walls for producing eddies on the right and left sides of the jet stream while preventing the stream from sticking to it. It also has claw-like portions contiguous to the side walls for dividing and dispersing the jet stream, so as to adapt the jet stream to curve to cause salf-vibration by alternately generated eddies in the right or left space between the side wall and the jet stream and pressure difference caused by absorptive effect arising from wake, and to disperse the jet stream with the claw-like portions for spraying the fluid around widely, is very useful as a jet nozzle for the water spraying device and cleaning machine.
