Abstract

PURPOSE:To control water feeding period correctly by setting the turning angle of a cam, by connecting a water inlet port to a water supply source and employing such an arrangement that a feed water valve is opened with turning of the cam and water supply is stopped through reverse turning of the cam that is caused when a water turbine disposed in a water turbine chamber is turned for feeding water. CONSTITUTION:When water is supplied from a water inlet port 8 connected to a water supply tap, a pressure-reducing valve 37 and a feed water valve 32 are both closed when a control member 44 is fitted in the groove 30 of a cam 28. However, these valves 32, 37 are opened when the cam 28 is turned by turning a knob 15, so that water is introduced into a water turbine chamber 7 and passed to a hose connecting port formed at a lower part of the chamber 7. By this water flow through the chamber 7, a water turbine 19 in the chamber 7 is caused to turn and a main shaft 14 is also caused to turn reversely to the direction in which it is turned at the time of setting the knob 15. Resultantly, the cam 28 is also turned reversely by a cam pin 31 and returned to its original position. Thereupon, the control member 44 comes again into engagement with the groove 30, so that the valves 32, 37 are both closed. Thus, water supply is stopped automatically.

When the water pressure is applied to the water flow valve ME, the water pressure applied to the water flow valve ME is greatly reduced by the above-mentioned pressure reducing valve we@release, so although the pressure receiving area of the water flow valve body is relatively large, the water pressure applied to the flow water valve body ME is relatively small. You can push it up. By opening the valve groove 54ato, a large amount of water starts to be supplied into the water wheel 117 from the water supply hole 8-b, and water is also supplied to the water tank from the drain hole 9. When starting water supply by rotating the cam as described above, that is, when determining the amount of water and the time, the movement of the cam allows the middle flow water valve to be opened by a relatively small amount. Water volume and time O setting can be easily and smoothly performed using the overhead operation force. In addition, by rotating the cam gourd, you can set the cam 180 angle and synchronize the water supply start timing, allowing you to accurately set the water amount and time. When the water supply from the water supply hole 8 to the water wheel chamber 7 is started by setting the desired angle, the water supplied into the water wheel 117 starts to rotate the water wheel as shown in 3rd HK. In this case, the water wheel is rotated in accordance with the amount of water supplied from the water supply hole 8 into the water wheel chamber 7, and when the amount of water is small, it is rotated at #i transport speed, and when the amount of water is large, it is rotated at #i transport speed.
When k are respectively rotated at continuous speeds. The rotation of this waterwheel crane is reduced by the reduction gear train UK, and the first gear! 2, this first gear! iph is transmitted to the main shaft MK, and the main shaft is returned and rotated at a low speed in the opposite direction from when it was set. By rotating the main shaft 14, the cam is set at a position rotated by the desired angle as shown above! 8#i cam bin 31
It is rotated back by IK. The rotational speed of the return rotation of the cam swamp is maintained at a constant speed when the amount of water supplied to the water turbine chamber 7 is maintained constant, that is, when the water pressure of the water supply is maintained constant. Therefore, if the water pressure of the water supply is maintained constant, the desired time and amount of water can be set accurately by changing the rotation angle of the cam 30. When water is being supplied to the room 7, the water flows through the water supply hole 8 from the tap and reaches the water flow control valve C.
The water is supplied to the water turbine chamber 7 through the control valve body 800 and the control passageway. In this case, when the water pressure of the tap water is relatively high and the flow rate flowing through the water supply hole 8 is large, the flow pressure acting on the control valve body 1) becomes large, as shown in No. 7HK, and the control valve body ω is SS* is moved largely toward the water turbine chamber 7 side, and this acts to reduce the opening degree of the control channel and reduce the flow rate of water supply, and the water pressure of the water supply is relatively low. When the flow rate flowing through the water supply hole 8 is small, as shown in Figs. 3 and 6, the flow pressure acting on the control valve body becomes large and resists the pipe control spring S3. By moving it slightly, the control surface becomes larger and the flow rate of water is increased. Therefore, even if the water pressure is low, the flow rate of the water supply is always controlled at a predetermined amount.
The time and flow rate can be set accurately by setting the rotation angle of the cam 10 without adjusting the water pressure of the water supply, for example, by adjusting the cock 0*m degree or the like. The return rotation of the cam 3 is carried out slowly by the rotation of the cam y When the cam S is rotated and is applied with rolling force O11 in the direction [return] due to the pressing force of the driven member 4, the cam S
The driven member easily fits into the cam groove as it quickly returns and rotates 1), thereby closing the pressure reducing valve W and flowing water 4a, stopping the water supply to the water tank, and at the same time the rotation of the water wheel. will also be suspended. As described above, since the cam swamp performs a rapid action, the timing of stopping the return rotation of the cam swamp and the water supply stop can be synchronized, making it possible to accurately set the time during water flow.

1m at the entrance of the water supply hole [When II opens the water valve and starts water supply, and the waterwheel in the waterwheel chamber is rotated according to the amount of water supplied, the above cam is returned by b) When it is returned to the position, the water flow valve is stopped and the water supply is stopped. Therefore, when maintaining the water pressure of the water supply at a constant level, the rotational speed of the cam, which is returned and rotated by the rotation of the water wheel, must be kept constant. By setting the cam rotation angle O, it is possible to set the time in the positive direction.

る効果がある。A flow control valve is installed in the middle of the water supply hole, and when the flow rate of water in the water supply hole is large, the large flow pressure causes the control valve body of the flow control valve to move against the control spring, causing the water wheel to move. The degree of opening of the control passage is reduced by sliding it largely toward the chamber side, and when the zero flow rate in the water supply hole is small, the control valve element is slid slightly by the small flow pressure to increase the degree of opening of the control passage, and the opening degree of the control passage is increased. Since the flow rate of the water flowing through the water wheel can be kept constant at all times, even if there are pressure fluctuations in the water pressure of the water supply source, the rotational speed of the cam that is rotated by the rotation of the water wheel can be kept constant at all times. This allows the water supply fl

It has the advantage that it can be made simple and manufactured at relatively low cost.
