<P>PROBLEM TO BE SOLVED: To provide a carbonated spring generating device capable of efficiently generating a carbonated spring without increasing the water pressure. <P>SOLUTION: The carbonated spring generating device has an air-bubble dissolving path 12 through which water having carbon dioxide bubbles mixed therein flows. The air-bubble dissolving path 12 has at least one constricted section 14 that divides the carbon dioxide bubbles, and a pressure holding section 16 that maintains the water pressure in the output side end of the air-bubble dissolving path 12 at the water pressure of inside the air-bubble dissolving path 12. The effective diameter of the air-bubble dissolving path 12 is stipulated such that the viscous resistance R of the air bubbles at the flow speed v of the water flowing through the air-bubble dissolving path 12 is at least the buoyancy F of the carbon dioxide bubbles when the carbon dioxide bubbles have a maximum diameter D as the effective diameter thereof, and the constricted section 14 has a smaller effective diameter than the air-bubble dissolving path 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
