<p>A liquid diluting device, wherein a diluent passage (12) for leading special liquid and a washing fluid feed passage (13) independent of the diluent passage (12) are formed in a main body (10), a plurality of jets (19) are fitted to a tubular dial (18), and a water moving passage is formed to communicate two positions wit a pressure difference in the washing fluid feed passage (13) with those jets (19b, 19c) other than the jets (19a) for leading the special liquid, whereby when water flows in the washing fluid feed passage (13), the water is allowed to flow in the water moving passage by the pressure difference in the washing fluid feed passage (13), the jets (19b, 19c) other than the jet (19a) for leading the special liquid is washed out by the water, and a variation in metering and clogging of the jets (19b, 19c) not used for long period can be prevented.</p> |
