Dual flush toilet valve system

Abstract

A flush regulator for a toilet tank for regulating the outflow therefrom through an outlet, said regulator including a valve without buoyancy, said valve adapted to close said outlet, a connector connected at one end to said valve and a body of buoyancy at another end of said connector above said valve, said valve adapted to close said outlet when the water level in said tank reaches the upper edge of said body of buoyancy and said buoyancy and valve fall to close said outlet wherein said toilet tank includes an overflow pipe wherein said body of buoyancy is connected to the overflow pipe by a plurality of attachment points and wherein the height of the body of buoyancy is varied by attaching the body of buoyancy using one of the plurality of attachment points so as to adjust the height of the body of buoyancy relative to said valve.

What is claimed is: 
     
         1 . A flush regulator for a toilet tank for regulating the outflow therefrom through an outlet, said regulator including a valve without buoyancy, said valve adapted to close said outlet, a connector connected at one end to said valve and a body of buoyancy at another end of said connector above said valve, said valve adapted to close said outlet when the water level in said tank reaches the upper edge of said body of buoyancy and said buoyancy and valve fall to close said outlet wherein said toilet tank includes an overflow pipe wherein said body of buoyancy is connected to the overflow pipe by a plurality of attachment points and wherein the height of the body of buoyancy is varied by attaching the body of buoyancy using one of the plurality of attachment points so as to adjust the height of the body of buoyancy relative to said valve. 
     
     
         2 . The flush regulator as claimed in  claim 1  wherein said body of buoyancy is installed on said connecting rod by a notched assembly between said body of buoyancy and said overflow pipe. 
     
     
         3 . The flush regulator as claimed in  claim 1  wherein said body of buoyancy is installed on said overflow pipe by a screw thread between said body of buoyancy and said overflow pipe. 
     
     
         4 . The flush regulator as claimed in  claim 1  wherein said body of buoyancy is frictionally clamped upon an intermediate socket to install the body of buoyancy at different levels. 
     
     
         5 . A flush regulator for use in a toilet tank for regulating the outflow therefrom through an outlet, said regulator including a valve without buoyancy, said valve adapted to close said outlet, a connector connected at one end to said valve and a body of buoyancy attached above said valve, said valve adapted to close said outlet when the water level in said tank reaches the upper edge of said body of buoyancy and said buoyancy and valve fall to close said outlet; wherein said valve and said body of buoyancy is guided by a guide. 
     
     
         6 . The flush regulator as claimed in  claim 5  wherein said toilet tank includes an overflow pipe to which said body of buoyancy and wherein a location on which said overflow pipe said body of buoyancy is connected is varied by turning said body of buoyancy to engage a plurality of attachment points so as to adjust a distance between said body of buoyancy relative said valve. 
     
     
         7 . The flush regulator as claimed in  claim 5  wherein said guide is clamped into a clip connecting said guide with a water inlet hose, said clip provided with an elastic area so that said guide is held fast at all installed radial positions during further operation of said flush regulator. 
     
     
         8 . The regulator for a toilet tank for regulating the outflow of liquid through an outlet comprising: (a) a valve for opening and closing said outlet; (b) means for locating said valve relative said outlet; (c) moveable buoyancy means disposed for slideable displacement relative said locating means for moving said valve from a closed position to an open position to permit said liquid through said outlet; (d) wherein said locating means is stationary relative said outlet and said buoyancy means slides relative said locating means when said valve is open for outflow of said liquid through said outlet; and (e) wherein said buoyancy means comprises: (i) a member to slideably embrace said locating means; (ii) a buoyancy member selectively moveable relative said slideable member to adjust the level of flush of said liquid; and (f) wherein said locating means comprises: (i) a generally cylindrical body having a hole therethrough; (ii) a retaining member having a bore therethrough for frictionally receiving and retaining said cylindrical body. 
     
     
         9 . The regulator as claimed in  claim 8  wherein retaining member comprises fastening means for fastening said retaining member to said overflow pipe. 
     
     
         10 . The regulator as claimed in  claim 9  wherein said hole in said generally cylindrical body is eccentrically disposed. 
     
     
         11 . The regulator as claimed in  claim 10  wherein said cylindrical body is frictionally rotatable within said bore of said retaining member for adjusting the distance between the centre line of said hole and rod to the centre line of said overflow pipe so as to position said valve over said outlet. 
     
     
         12 . The regulator as claimed in  claim 11  wherein said cylindrical body includes a cylindrical extension having a diameter smaller than said cylindrical body. 
     
     
         13 . The regulator as claimed in  claim 12  wherein said hole through said cylindrical body extends through said extension. 
     
     
         14 . The regulator as claimed in  claim 13  wherein said rod is disposed for slideable movement through said hole and said rod is connected to said valve and said slideable member. 
     
     
         15 . The regulator as claimed in  claim 14  wherein said rod is fastened to said valve by a ball and socket joint. 
     
     
         16 . The regulator as claimed in  claim 15  which is adapted to be retrofitted to any existing toilet and wherein the level of flush is adjusted by moving said buoyancy member relative said slideable member.
