The disk 50 is coupled to the second shaft 30 to open and close the instantaneous index passages 43 and 44 while being lifted, and may be fixed to the second shaft 30, but the second shaft 30 may be fixed. When the second shaft 30 is pressed more than the first shaft 20 (that is, the user is surely pressed by the second button) by being caught by the nut 32a at the lower end and the step 33 at the upper part thereof. Only when (37) is pressed.

The pressure discharge passage 47 is formed through a gap between the first shaft 20 and the opening / closing member 40 and a gap between the second shaft 30 and the disk 50, and the water channel 11 and the pressure chamber. It is a passage which communicates 15 with each other, and discharges the water filled in the pressure chamber 15 to the water channel 11, and is comprised so that it may open and close by the pressure switching member 60. As shown in FIG.

The pressure opening and closing member 60 is a ring body which is coupled to the lower end of the first shaft 20 to open and close the pressure discharge passage 47, and is elevated and integrated with the first shaft 20 so that the opening and closing member 40 is first. Before the elevating by the shaft 20, the pressure discharge passage 47 is first opened and closed.

The water-saving valve according to the above configuration, when the user presses the first button 27 and the second button 37 at the same time, the channel 11 until the opening and closing member 40 is caught by the upper snap ring 24 Is maintained in a closed state, but the pressure opening and closing member 60 of the lower end of the first shaft 20 is lowered integrally with the first shaft 20 to open the pressure discharge path 47 to fill the pressure chamber 15. The lost water is discharged to the water channel 11 through the pressure discharge path 47. Subsequently, when the opening / closing member 40 is caught by the snap ring 24, the water channel 11 starts to discharge water while being lowered integrally with the first shaft 20.

As such, when the first button 27 and the second button 37 are released while the water channel 11 is open, the first shaft 20 may be driven by the elastic force of the spring 28 as shown in FIG. 2. As it rises, the pressure discharging passage 47 is closed by the pressure opening / closing member 60 coupled to the shaft, and the water in the channel 11 through the pressure inflow passages 45 and 46 of the opening / closing member 40 is closed. The opening and closing member 40 is raised while being slowly filled and filled into the pressure chamber 15. In this pressure water inflow process, the water in the water channel 11 introduced through the pores 45 is completely filled in the pressure chamber 15 so that the opening / closing member 40 is in close contact with the sheet portion 12 of the water channel 11. Since it continues for a predetermined time until closing 11), during this time, the channel 11 is opened so that a predetermined amount of water can be discharged and used.

Meanwhile, in the process of simultaneously discharging water by simultaneously pressing the first button 27 and the second button 37, when only the second button 37 is pressed again, the bottom of the opening / closing member 40 is lowered. The disk 50, which is in close contact with the instantaneous index passages 43 and 44, is caught by the locking jaw 33 of the second shaft 30 and descends to open the instantaneous index passages 43 and 44. As such, when the instantaneous index passages 43 and 44 are opened, water in the channel 11 flows into the pressure chamber 15 in large quantities through the instantaneous index passages 43 and 44 having a plurality of through holes 44. The opening and closing member 40 is quickly raised to close the waterway 11 and stop the discharge of water.

Therefore, this instantaneous exponential process, when the user wants to use a small amount of water simply press the second button 37 once again the waterway 11 is quickly closed, there is an advantage that can save water .

On the other hand, Figure 4 is a cross-sectional view showing another embodiment of the present invention. Referring to this, in this modified example, a predetermined support plate 70 is installed on the inner circumferential surface of the opening / closing member 40 or the pressure chamber 15, and the disk 50 is provided between the support plate 70 and the disk 50. It is configured by installing a spring 75 which is further supported upward. Therefore, this modified example is that when the second button 37 is pressed again to release the force for pressing the second button 37 when opening the instantaneous index passages 43 and 44, the disc 50 will be Since the instantaneous index passages 43 and 44 are quickly closed due to the elastic force of the spring 75, the water in the channel 11 in a large amount is pressurized while the user presses the second button 37. ), It is possible to conveniently adjust the discharge time of the water.

As described above, according to the present invention, the water supplied through the tap water can be discharged in a predetermined amount, and when necessary, the water can be quickly discharged, thereby increasing the water saving effect and being conveniently used.
