Abstract
A flushing arrangement (30) including an opened topped housing (32) surrounding the flush valve (12). An opening (40) is provided in a lower part of the housing (32) with a selectively openable gate (44). The arrangement (30) is configured such that for a low volume flush the gate (44) is closed and only water in the housing (32) or located thereabove will be flushed, and for a high volume flush the gate (44) is open wherein substantially all of the water in the cistern (20) above the lowest part of the opening (40) is flushed.

A toilet flushing arrangement comprising an open topped sleeve locatable in a toilet cistern to surround the flush outlet, with a selectively openable opening provided in a lower part of the sleeve, such that the arrangement provides two flushing modes:
- a low volume flush with the opening closed, wherein substantially only the water within the sleeve plus the volume of any water located above the top of the sleeve, is flushed;
- and
- a high volume flush with the opening open, wherein substantially the volume of the water in the cistern, whether or not in the sleeve, above the lowest part of the opening is flushed,
- a control arrangement being provided with a pivotally moveable handle, such that a first pivotal movement thereof causes a rotation of a cam member that rotates a lever bar resulting in said low volume flush, and further pivotal movement of said handle in the same direction causes said cam to open a closure member covering said selectively openable opening to allow said high volume flush.
A toilet flushing arrangement comprising:
- an open top housing surrounding a flush outlet having a high volume flush opening along the side of said housing;
- a control arrangement rotably connected to a cam assembly having first and second lobes;
- the first lobe rotating a first linkage assembly during a low volume flush and the second lobe rotating a second linkage assembly during a high volume flush, the second linkage assembly being connected to a selectively operable gate covering said high volume flush opening during a low volume flush and is rotated away from the high volume opening during a high volume flush.
A toilet flushing assembly having multi-volume flush capability comprising:
- a housing positioned in a toilet tank surrounding an outlet valve, the housing having a high volume opening near the base thereof;
- a closure member for the high volume opening, the closure when in use being moveable between a closed position blocking flow through the opening and an open position allowing flow through the opening;
- a lever arrangement connectable to a cam assembly connectable to the outlet valve for both a high volume and low volume flush, the cam assembly also being connectable to said closure member to move the closure member to its open position to permit flow through the opening for a high volume flush, such that rotation of the lever arrangement results in a first rotation of said cam assembly producing a low volume flush and further rotation of the lever arrangement to a second rotation of the cam assembly in the same direction producing a high volume flush.
