Definitions

• This invention is related to the dual flush system designed for the toilet reservoir, capable of two different flush volumes as an adjustable small volume and a constant large volume.
• a dual flush system is disclosed in the published American patent application US2004/0083542, in prior art.
• the upward motion of the overflow tube is provided by means of a cam mechanism pushing overflow tube upward by pulling a wire connected to a group of buttons.
• the overflow tube and the button group function together such that the overflow tube cannot perform its function without this special button group.
• the system contains too many mechanical parts, and it is deduced that their production costs are high due to their structural complexities.
• the pool floater used for small volume flush pulls the adjustment rod upward, and forces the movable member, which has protrusions to engage the hooks on the overflow pipe and which is connected to the adjustment rod, to rotate towards the overflow pipe, as long as the reservoir is full of water.
• the moveable member is disengaged from the overflow tube and overflow tube with its gasket is seated in to the discharge hole.
• the mentioned system can be connected to the various lifting mechanisms.
• the object of this invention is, to produce a dual flush system; that is easy to assemble, durable, allowing the user to flush the entire or a predetermined volume of water inside the reservoir; and that can be connected to various lifting mechanisms.

• the large volume hook (93) forms an inclined surface that extends out from the overflow tube guiding rail (92) at a point with an angle and a certain length.
• the small volume hook (94) also forms an inclined surface that extends out from the overflow tube guiding rail (92) at the mentioned point with an angle and a certain length.
• the small volume hook (94) is shorter; the bottom part of the large volume hook (93) is placed lower than the bottom part of the small volume hook (94).
• the overflow tube guiding rails (92) on the overflow tube (4) are placed in the flush body upper hole channels (84) so that overflow tube (4) is movable only in vertical direction.
• flush valve base (1 ) is placed to the discharge channel of the toilet reservoir, together with the flush valve base sealing gasket (2) on it.

Consequently, the small volume pool floater (12) is attached to the small volume adjustment rod (11 ) via its small volume pool floater threaded surface (77).
• the large volume floater contact surface (43) and the small volume floater contact surface (53) on the large volume floater (9) and the small volume floater (10), respectively, are positioned to lean on the overflow tube (4), and their positions are achieved by hinge points of large volume floater pins (40), and small volume floater pins (50) being pivoted on the floater holes (87) of the flush body (3), and by the air being captured inside the large volume floater inner space (46), and small volume floater inner space (56) by the water inside the reservoir during refill.
• the overflow tube (4) When the overflow tube (4) is completely lifted upward, the large volume floater hooks (45) are engaged to the surface below the large volume hook (93) by contacting of the large volume floater hooks (45) with the large volume hook (93) on the overflow tube (4), the overflow tube (4) is hung on the large volume floater (9) in this position.
• the lifting force of water causing the large volume floater (9) to rotate and lean to the overflow tube (4) begins to decrease, and by the weight of the overflow tube (4) the large volume floater (9) is pushed downward and disengaged from the overflow tube (4) by rotating outwards.
• the volume of the flushed water is the large volume in between the highest water level in the reservoir and the bottom level of the large volume floater (9).
• the overflow tube (4) is lifted upward a shorter distance.
• the small volume floater hooks (55) are engaged to the surface below small volume hook (94) by contacting the small volume floater hooks (55) with small volume hook (94) on the overflow tube (4), the overflow tube (4) is hung on the small volume floater (10) in this position, and at that instant flushing initiates.
• the weight of the small volume pool floater (12) with full of water is transmitted to the adjustment rod (11 ), and to the small volume floater (10).
• the lifting force of water causing the small volume floater (10) to rotate and lean on the overflow tube (4) begins to decrease, and by the weight of the overflow tube (4) together with the weight of the small volume pool floater (12) with full of water, the small volume floater (10) is pushed downward and disengaged from the overflow tube (4) by rotating outwards.
• the volume of the flushed water is the small volume in between the highest water level in the reservoir and the bottom level of the small volume pool floater (12) or slightly its lower level.
• the position of the small volume pool floater (12) can be changed upward or downward by means of the threaded surfaces on the small volume adjustment rod (11 ) and small volume pool floater (12).
