Rod 42 is designed with a predetermined amount of transverse flexibility, i.e. is flexible transversely. For example,rod 42 is made of plastic (polymer material) and is thin enough to flex crosswise. - When installing
valve assembly 1, after adjusting the height (measured along axis A) ofvalve assembly 1 by means ofheight adjusting mechanism 20, to adaptvalve assembly 1, if necessary, to the size of the tank, the user adjusts the amount of water discharged by means of regulatingsystem 5. - To adjust the amount of water discharged, the user releases
coupling 43 and movesgate 38 usingrod 42. -
Coupling 43 is released by simply pullingend 46 ofrod 42 radially (i.e. horizontally, crosswise to axis A) to releaserod 42 fromcatch element 45. The flexible nature ofrod 42 allowsend 46 to flex tofree rod 42 fromcatch element 45. - Once
coupling 43 is released,rod 42 is slidable axially, parallel to axis A, together withgate 38 to movegate 38 into its various operating positions with respect towindow 16, and so adjust the opening ofwindow 16. - Once set the chosen position,
rod 42 is inserted back intocatch element 45, again moving horizontally, crosswise to axis A, to securerod 42 once more to supportingstructure 2. - The positions of
gate 38 are marked by user-visible wording or symbols (indicating, for example, the amount of water discharged in each position). - Adjusting the opening of
window 16 adjusts the water level insidevessel 7, and therefore the operating level offloat 31 housed insidevessel 7, and the amount of water discharged. Regulatingsystem 5 thus provides for adjusting the water level insidevessel 7 and therefore the operating level offloat 31 housed inside it. - Clearly, changes may be made to what is described and illustrated herein without, however, departing from the scope of the invention as defined in the accompanying Claims.
