<P>PROBLEM TO BE SOLVED: To provide an air mixing jet type flow fitting and a check valve with outstanding durability and provided in an air mixing jet mechanism which have very small intake resistance and allow a large amount of outside air to be sucked thereby to enable an air-mixed jet containing large amount of air to be formed, and to cause no vibration nor noise. <P>SOLUTION: In this air mixing jet type flow fitting in a water passage formed between a discharge part and a water supply part, provided with the air mixing jet mechanism, a structure is employed in a ventilation path so that the ventilation path is opened by the pressure of pressurized water supplied to an injection nozzle and that the ventilation path is closed when the pressure of the pressurized water supplied to the injection nozzle decreases and/or the air mixing part side pressure increases. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
