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.

- floater holes (87) lying next to each other and on the same level, which are just above the flush body lower protrusion (85).
- Another pair of floater holes (87) on the flush body (3) lies on the same axes with the first pair of floater holes (87).
- Overflow tube (4) shown in figure 9 comprises the following mechanical details; hook attachment holes (91 ), overflow tube guiding rail (92), large volume hook (93), large volume hook (94), and ring-gasket seating surface (95).
- the overflow tube (4) shown in figure 9 has a shape of cylindrical hollow tube, which is open at the top and the bottom, containing two hook attachment holes (91 ) for hanging the flush lift arm (5) at the upper side, and also, containing the ring-gasket seating surface (95) made by a diameter reduction where the two retaining rings (14) and the flush gasket (15) in between the rings (14) which are mounted at the lower side.
- On the overflow tube there are two overflow tube guiding rails (92) which are placed mutually and lying from top to bottom.
- the large volume hook (93) and the small volume hook (94) lie next to each other.
- 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.
- the flush valve base support (8) of which the upper part is leaned to a fixed point in the reservoir, is connected to the flush valve base (1 ).
- the flange (16) is placed just above the flush valve base (1 ), and it is also is located in at the inner side of the flush body lower protrusion (85).
- the flush body (3) besides, is attached to the hook-attachment parts on the flush valve base (1 ) via its flush body hooks (81 ).
- the hooks on the flush lift arm (5) are attached to the hook attachment holes (91 ) on the overflow tube (4). Due to the fact that the overflow tube guiding rails (92) on the overflow tube (4) are guided in the flush body upper hole channels (84), the overflow tube (4) is guided in the flush body upper hole (83). On the ring-gasket seating surface (95) of the overflow tube (4), two retaining rings (14) and in between the flush gasket (15) are mounted on top of each other. In case of the overflow tube (4) being not pulled upward, the flush gasket (15) closes the hole in the middle of the flush valve base (1 ), and prevents the water flow from the reservoir to the toilet.
- the overflow tube (4) extends downwards throughout hole in the middle of the flange (16). Since large volume floater pins (40) and small volume floater pins (50) are attached to the floater holes (87), which are on the flush body (3), the large volume floater (9) and the small volume floater (10) are positioned inside the flush body (3). Also, the overflow tube (4) is in between the large volume floater (9) and the small volume floater (10).
- the small volume adjustment rod (11 ) is also placed inside the flush body (3); via its bearing protrusion to flush body (62), it leans on the surface just below the adjustment rod attachment hole (86) when the reservoir is full; and at the same time via the small volume floater attachment protrusions (65) at its bottom part, it is attached to the adjustment rod attachment hooks of the small volume floater (58); via its small volume floater attachment surface (64), it is placed on the adjustment rod attachment surface of the small volume floater (57). 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).
- the dual flush system (A) can also be used in various reservoirs with liquid contents.
