PURPOSE:To adjust easily and securely water-feed hydraulic pressure by operating a float with water in a tank by using water as a medium and connecting and separating a valve and a valve seat. CONSTITUTION:Air pressure in the tank 1 is adjusted to set air pressure through a pump 15. A little amount of high pressure water flowed in from a space between the valve seat 6 and the valve 7, which is suspended on a rocking lever 13 through a joint lever 9, through an inflow pipe 2 and a casing 4 is fed to a water feed pipe 16 from a discharge pipe 3. Basing on the installation of a branching pipe 5 the water in the tank 1 disappears slowly, and simultaneously its air pressure drops slightly, whereby the oscillating lever 13 is brought into the state where its top is up (the valve side is considered to be a top). Accordingly many spaces A develop, and a large amount of high pressure water flowed in through the inflow pipe 2 and the casing 4, is fed to the water feed pipe 16 from the discharge pipe 3. Simultaneously the high pressure water flows back to the tank 1 from the branching pipe 5 of the discharge pipe 3. |
