FIELD OF THE INVENTION [0001] 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. BACKGROUND OF THE INVENTION [0002] The decreasing natural resources have resulted in the need to reduce the amount of water used in the closets. Among the methods of fulfilling this need in reservoirs; interruptible flush systems, closets that can function with less than 6 lt of water, and the systems called as dual flushing systems that can perform washing with two different volumes, are used. The opportunity to wash with two different volumes in dual flush systems has made water conservation possible by performing smaller volume washing without using the entire volume of water in the reservoir in case the closet is filled with urine or easily removable pieces such as dust or paper. [0003] A dual flush system is disclosed in the published American patent application US2004/0083542, in prior art. In this system, 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. In this system, the overflow tube and the button group function together such that the overflow tube cannot perform its function without this special button group. Also, the system contains too many mechanical parts, and it is deduced that their production costs are high due to their structural complexities. [0004] In US2004/0083542, 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. In this mechanism, when the water is flushed from reservoir, by means of the weights of the adjustment rod and pool floater, and the force exerted on the moveable member by the overflow tube, the moveable member is disengaged from the overflow tube and overflow tube with its gasket is seated in to the discharge hole. [0005] Main difference of the system disclosed in this application with US2004/0083542, besides the used parts being geometrically in different forms, is that the small volume flush mechanism works in a different way than the one in US2004/0083542. In the system, which is the subject matter invention, the part that pulls down the small volume mechanism and causes the disengagement from the overflow tube is the small volume pool floater that is permanently filled with water. The weight of the pool floater, filled with full of water, helps this system functioning as a more reliable manner. [0006] Additionally, the mentioned system can be connected to the various lifting mechanisms. OBJECT OF THE INVENTION [0007] 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. DETAILED DESCRIPTION OF THE INVENTION [0008] The mentioned system is indicated in the attached figures and the explanation is here below; [0009] FIG. 1.
