Flush tank having flush water adjusting device

Abstract

A flush tank includes a water housing having an outlet port, a device for controlling the inward flow of the water into the housing, a valve received in the housing for selectively engaging with the outlet port, a link coupled to the valve for disengaging the valve from the outlet port by such as a lever, and a float attached to the link for controlling the disengagement of the valve from the outlet port. A stop is adjustably secured to the link for adjusting or limiting the upward movement of the float relative to the link and for adjusting the outward flow of the flush water.

I claim:

         2 . The flush tank according to  claim 1  further comprising means for adjusting said float relative to said link.  
     
     
         3 . The flush tank according to  claim 2 , wherein said adjusting means includes a stop engaged on said link for limiting an upward movement of said float relative to said link.  
     
     
         4 . The flush tank according to  claim 1  further comprising a weight selectively attached to said link.  
     
     
         5 . The flush tank according to  claim 1 , wherein said valve includes a casing provided therein, said flush tank further includes a weight received in said casing of said valve.
