Abstract

An automatic water stopper employed by connecting directly to a water supply pipe or to the faucet of a garden water supply pipe to terminate the supply of water automatically when the amount of metered water flowing from the supply pipe reaches a given quantity which has been preset by means of a dial. An impeller for metering the amount of water obtained from the supply pipe, and a ball that closes a valve opening after the prescribed amount of water has been supplied, are arranged at positions close to each other on a straight line lying along the flow path. This permits a reduction in the total length of the flow path from the water inlet toward the water outlet so that the apparatus can be made small in size. In addition, the amount of water to be supplied can be set through a simple operation similar to that employed to operate an ordinary faucet, that is, by turning a single dial that sets the desired water quantity.

Title of invention Automatic water shutoff device

Technical field

The present invention measures the amount of water flowing out of a faucet of a domestic water supply pipe or a water supply pipe directly connected to a water supply pipe, and more particularly, to an automatic water stop device. O Automatic water stop device that automatically stops water supply after reaching a set water volume o

Background technology

Conventionally, as a device for measuring the amount of water flowing out from a water supply pipe and stopping the water supply after a predetermined amount of water has been supplied, Japanese Patent Publication No. 33-10990, Japan The devices disclosed in Japanese Patent Publication No. 33-1090, in which the Japanese Patent Publication No. 35-80035 and the Japanese Patent Publication No. 386938, are known. The rotation of the impeller, which rotates on the water channel due to the water flow flowing from the inlet, is transmitted to the operating needle by reducing the rotation of the impeller, and the operating needle is rotated a predetermined amount from the reference position in advance. The reference position is returned by the rotation of the impeller, and when the operation needle returns to the reference position, the operation needle is set at the top of the cylindrical cam, and the valve is cultivated. And closing the valve at the lower end of the valve rod, which had previously opened the water channel, to supply water in an amount corresponding to the amount of rotation of the operating needle. In order to supply a specified amount of water using this device, the operating needle and the hand must be connected together. It has to be operated separately, the operation of setting the water supply is complicated, and the normal faucet is operated ^ However, the device disclosed in Japanese Patent Publication No. 35-8035 has a problem in that it cannot be easily operated. Then, the rotation of the impeller rotating on the water path is reduced and transmitted to the coaxially co-rotating spiral type hand with the hand (hand) and the hand (hand), so that the reference position can be set in advance. After returning the ZJ dollar and spiral drum to the reference position, and when the hand returns to the reference position, the outer surface of the spiral coil is The valve rod, whose end was abutted by spring force, falls into a step formed on a part of the outer circumference of the spiral force, and the valve at the end of the valve rod closes the flowing water channel. (D) A limited amount of water is supplied in accordance with the amount of rotation of the valve. O A certain amount of power; however, the valve rod disclosed herein The impeller and ^ ZJ ") move along the direction perpendicular to the axis of rotation of the shim, so the space between the impeller and the valve provided at the tip of the valve rod is orthogonal to the plane of rotation of the impeller. A flow path having a length that is within the range of movement of the flow path and the valve is required. The device disclosed in Japanese Patent Publication No. 38-6938 discloses a method for reducing the rotation of an impeller driven by water flow. Both of them are released by the switching mechanism and transmitted to the cam board which rotates together with the head via the own clutch mechanism. When setting the water supply amount, first switch off the impeller force by the switching hand; After a predetermined amount of rotation Ri by the reference position Le, and it has blade grass operates the Ha nd le again Ha When the blades were connected to each other by the clutch machine and the huddle was rotated by the rotation of the impeller and returned to the reference position, -The rear end of the valve rod falls into the step formed in a part of the outer periphery of the force plate by the same operation as the device disclosed in No. 80035, and the water flow path is formed by the valve at the valve end. By closing the valve, water is supplied in an amount corresponding to the amount of rotation of the head j. In the meantime, when setting a predetermined water supply amount, this device must also operate two members, a hand and a switching hand). Therefore, it is troublesome to set the amount of water supply, and the water flow between the impeller and the valve is the same as in the device disclosed in JP-B-35-8035. The problem is that the entire flow path becomes longer by the length of the device, which hinders the miniaturization of the entire device. At this point, if a device that supplies a predetermined amount of water is connected to a domestic water supply pipe, especially a faucet, and used, the same as when operating a normal faucet. The required amount can be easily set by simply operating the hand, and the flow path connecting the valve, which is the water stopping means, to the impeller, which is the measuring means, is short, and the entire device It is the most desirable that the above-mentioned prior arts be considered in view of this point, but both of them are the above-mentioned two points, that is, The two points are that the water supply can be easily set with only one operation and that the flow path in the device is as short as possible to reduce the size of the device. It may be difficult to resolve. The present invention has been made under such circumstances, and the present application It discloses a further improved invention of the invention proposed in Japanese Patent Application No. 55-1333-183 already filed by a person.

Disclosure of the invention

The present invention is a small-sized monolithic structure suitable for being used by being directly connected to a faucet of a domestic water supply pipe or a water pipe, and setting an individual water amount. It discloses an automatic water shutoff device that can set a predetermined water supply amount with a simple operation similar to the operation of a normal faucet called a rotating operation.o This device is basic And a canal with an inflow port and an outflow port, and the inside of which serves as a flow channel, and a water flow from the inflow port to the outflow port with the valve port provided between the inflow port and the outflow port And an impeller that is rotated in one direction by the water flow from the inflow port to the outflow port. The water volume setting is fixed to one end of the rotating shaft, and the water volume setting device moves back and forth in conjunction with the rotation of the water volume setting device. The control rod that opens and closes the valve opening with a boss corresponding to the tip, and a water volume setting ^ The water volume is set by co-rotating coaxially with the rotation axis of the j j. A cam wheel that converts the rotational motion of the shaft into a reciprocating motion of the control rod, a reduction gear group that reduces the tillage of the impeller and transmits it to the cam wheel, a final gear and a gear group of the reduction gear group and ₀ its the beam vehicles Ri force grass by the final tooth car is connecting means and good Ri搆成be coupled to the jar by transmitting only the rotation of the ring, feather is driven Tsu by the water flow棂車Set the water flow in the direction opposite to the direction in which the vehicle will rotate according to the rotation of the vehicle. At the time of setting, the amount of water from the reference position is set.The amount of water corresponding to the amount of rotation of the dial rotates the impeller a predetermined number of times, and after the water is supplied from the outlet, the valve port is The desired amount of water can be supplied by blocking the water and stopping the water supply.Water supply of an arbitrary amount can be performed, and the water supply amount can be set only by turning the water amount setting knob. The rotation axis of the impeller, the control shaft, the water flow setting file, the rotation axis of the impeller, and the rotation axis of the reduction gear group are -parallel, and are in the same plane as the rotation surface of the impeller. Are arranged in series in close proximity to the impeller along the straight line on the flow channel from the inlet to the outlet, which is a water stopping hand and a means for measuring the amount of water. Therefore, the flow path between the wheels can be shortened, so that the entire flow path in the cage can be shortened, and the device can be downsized. In particular, in the case of a device in which the inlet and outlet are connected by a straight vertical water channel, the height of the entire device is shortened, and the Thus, it can be applied to places where there is a sufficient distance between the faucet and the flood line. When this automatic water shutoff device is used as a mixing tap for hot and cold water, the impeller and the port are connected in series along the flow direction, as will be described in detail in a later embodiment. The water inlet and the water inlet required as a mixing tap and the hot water control head attached to each of the inlets can be placed in close proximity to the water outlet. The valve and the impeller can be accommodated in the small space between the two heads J, which is not restricted by the above, and the automatic water stop device is built in. The entire shape of the hot and cold water mixing tap can also be finished in a compact size. Also, in the present invention, the apparatus is mounted on a faucet, and includes a connecting ring screwed to a cane around the inflow port, and a member fixed to the faucet. It discloses mounting means consisting of a fixed ring that is held by itself in rotation to the connecting ring, and the mounting means allows the device to be mounted on the faucet with respect to the faucet. This can be done simply by turning the ring without turning the device.

The present invention also provides a means for preventing the occurrence of a water hammer action at the moment when water supply is stopped, that is, when the valve port is completely closed by a port. In addition, the valve seat has a unique shape that gradually reduces the impact force received, and the port is located at a position where it is not possible to close the valve port at the front end during water supply. At the moment when the water supply stops, it suddenly retreats, and the control rod, which attempts to release the position regulation for the port suddenly, is slowed down. ) A speed control means for increasing the time until the valve completely closes the valve port is disclosed. Ο Further, the present invention provides a means for preventing backflow from the outlet. This is used to introduce air to the hose that is fitted around the outer circumference of the hose connecting pipe that protrudes from the outlet edge. It discloses the structure of a ventilation groove formed in the hose connection pipe and the structure of a porcelain valve formed in the hose connection pipe.

Further, one of the features disclosed in the present invention is that friction is provided as a connecting means for connecting the reduction gear group and the power train so that the latter transmits only the rotation of the alligator from the former. By adopting a knurled construction using a clutch, the water volume setting can be reversed.

, It can also be rotated in the direction of misalignment, and it may be easy to overturn the water amount setting tire I when setting the water supply amount, or to easily change the set amount. Then, set the amount of water to be cultivated together with the vehicle. When the water flow setting file is rotated in one direction from the reference position, the impeller tries to rotate by receiving the power. When the water volume setting ear is set at a position that is rotated in one direction from the reference position by adopting a stopping means that stops the rotation of the cam wheel, it is related to the rotation of the impeller. The car is set for water flow! When the water stops at the same time and the water is intermittently supplied from the outlet and is rotated from the reference position in the opposite direction, the water volume is set at the position where the water flow is set. With the rotation of the vehicle, the vehicle and the water volume setting are decelerated and the reference position is decelerated and the water volume setting is performed, and a limited amount of water is supplied according to the rotation amount of the water volume. Ο In other words, the water flow setting is the same as that of a normal faucet, and the two functions of continuous water supply and limited water supply can be selected by changing the rotation direction at the time of setting. It has the following characteristics.

The present invention is further provided with additional means having various useful features as described below. Ο First, the water amount setting is related to the operation of the vehicle and the control rod. Immediately after setting the water supply position together with the vehicle, the impeller starts to decelerate and rotate by a predetermined angle with respect to the rotation transmitted by the impeller, and When the wheel and the control rod correspond to the position where the position restriction is released, the By adopting a means for the vehicle to rotate the cam vehicle ahead of the above-mentioned predetermined angle earlier than the rotation speed at which the rotation is driven very slowly, the water supply When the motor stops, the control rod is quickly driven by the cam wheel to close the valve port with a ball in a short time, and the rotation of the impeller is reduced. Although the vehicle is transmitted to the motor vehicle and the vehicle rotates very slowly, the water stopping operation can be completed quickly. Yes o

Also, as for the friction clutch related to the steel structure, the internal gear is the clutch wheel that is combined with the final gear of the reduction gear group. The axis of the clutch plate that is in E-contact with one surface of the gear, that is, the rotation axis of the cam wheel and water volume setting dial, and the rotation axis of the final gear can be brought close to each other, and the rotation transmission In addition to reducing the space occupied by the entire transmission mechanism, which contributes to the miniaturization of the entire device, a large contact area can be secured between the clutch plate and the internal gear, and friction friction can be reduced. Large transmission force can be applied to the latch. O In addition, what is different from this friction clutch is that the rear end of the control rod is used during continuous water supply. A spring means for contacting one side of the vehicle with E to regulate the cultivation of the vehicle is used together with this friction clutch. As a result, the impeller, which is rotated and driven during continuous water supply, receives a certain amount of force and prevents the power wheel and water volume setting from rotating. O Disclosed is a configuration in which an intermittent water supply operation can be achieved with the same water volume setting ^

Also, as a means to stop the cultivation of the car during continuous water supply

, ο: .ί? ι In addition to the combination of the above-mentioned friction clutch and spring means, the rotation transmission between the impeller and the reduction gear group is performed by magnetic coupling, and the continuous water supply is set to a sufficient water amount. It discloses a mechanism that employs a latch mechanism that stops the rotation of the reduction gear group by hooking on the gears of the deceleration gear group when rotated. According to the above, continuous water supply operation can be achieved with the same water flow setting as in the above-mentioned case where limited water supply is performed.

Further, in the present invention, a chamber in which the impeller and the plow are arranged and a chamber in which the reduction gear group is housed are related to the magnetic coupling between the impeller and the reduction gear group. A structure is disclosed that prevents water from flowing from the inlet to the outlet from accumulating near the reduction gear group and adversely affecting the operation of the reduction gear group.

The control rod 40, which moves back and forth with the rotation of the cam wheel 41 and the power wheel 41 to control the position of the wheel 11, and the rotation of the cam wheel 41 The water amount is set so that the cam wheel 41 can be rotated at an arbitrary angle by being arranged coaxially with the drive shaft 31 and rotating it. O

Fig. 1 to Fig. 4 show that a straight water channel is formed between the inlet 2 at the upper end of the cake 1 and the outlet 3 at the lower end of the cake 1. The figure shows an example in which the pole 11 and the impeller 20 are arranged in series along the water channel. O The water tap faucet 6 4 is connected to the inlet 2. Therefore, a double pipe 65 composed of an inner pipe 60 and an outer pipe 61 surrounding the inner pipe 60 is formed on the periphery of the inlet 2, and a step provided in the inner pipe 60. A link-shaped pad 67 formed of an elastic body such as a rubber is mounted on the part 16 via a washer 17. A fixed ring 63 having an inner diameter substantially equal to the inner diameter of the inner tube 60 is fixed to a periphery of the tip of the faucet 64 by a screw 57, and is connected to the fixed ring 63. The ring 62 is rotated freely, and Ring 6 2 o The fixed ring 6 3 below Tan椽that it males were found provided Flip portion ₅ 8 is screwed with the female I Flip unit 6 6 the outer tube 61 the inner wall to the outer peripheral Wataru connexion outside flange all around It is concluded when 6 8 is formed

CM? IO An inner flange 69 is formed on the upper edge of the ring 62 over the entire circumference, and the inner ring 69 is locked to the outer flange 68 so that the connecting ring 62 can rotate. O Protrusions 56 protrude from appropriate places on the outer periphery of the upper edge of the connecting ring 62 so that the connecting ring 62 can be easily turned when it is turned by hand. Therefore, in order to attach the automatic water blocking device to the faucet 64, first insert the faucet 64 into the stationary ring 63, and then tighten the screw 57 to secure the stationary ring 63. Is fixed to the faucet 64, and then the connecting ring 62 is rotated while holding the protrusions 56 of the connecting ring 62 while supporting the cake 1 by hand so that the cake 5 does not co-rotate. With the screwing of the outer tube 61 and the connecting ring 62, the cake 1 moves upward and the tip of the faucet 64 comes in E-contact with the packing 67, and the water supply Connect pipe 6 4 to inlet 2 Even if the water pressure is considerably high, there is no possibility of water leaking from the connecting part ', and the inside of the pad 67 and the faucet 6 This is the one that makes sure to make E-contact without rotating relative to each other, so that the tip of the tap 67 and the tip of the faucet 64 rub against each other. There is no answer. In this way, when the outer tube 61 and the connecting ring 62 are screwed together and the fixed ring 63 comes into contact with the inner tube 60, the overtightening of the connecting ring 62 can be prevented. Ο In the figure, reference numeral 59 denotes a synthetic resin cover fitted to the stationary ring 63, and the projections 47 are inserted into holes 46 provided in the stationary ring 63. As a result, it is attached to the fixed ring 63, and the lower end edge of the cap 59 presses the connecting ring 62 to prevent the connecting ring 62 from rattling. in filtration come and one O?

The water channel is separated by a partition plate 4, and the upper part of the channel is

The water shutoff chamber 15 containing 11 is also a weighing chamber 27 containing the lower impeller 20. Position of 11 is controlled by the control rod 40 whose tip moves back and forth in the water stop chamber 15, and the control rod 40 moves forward and projects into the water stop chamber 15. At this time, when the port 11 is pushed out at a position where the valve port 10 provided on the partition plate 4 cannot be closed, the control rod 40 is retracted. Is Po! The above-mentioned position restriction on the spring 11 is released, and the water 11 moves to a position to close the valve port 10 by the water E. The periphery of the valve port 10 has a minimum inner diameter substantially equal to that of the valve port 10: A flat link-shaped valve seat 14 formed of an elastic body such as j is attached. As shown in Fig. 10, this valve seat 14 is gradually opened as it goes outward on the lower surface, and has a wrapper-shaped notch 12 whose diameter increases and has a A thin band 13 is formed over the entire circumference of the opening 18 around the opening 18, and the bore j 11 closes the opening 18 of the valve seat 14 to open the opening 1. When closing 0, if the water pressure is low, only the thin-walled belt 13 will open, and if the water pressure increases, the inner circumference of the valve seat 14 will also bend, and the water E will increase further. The notch 1 2 on the lower surface of the valve seat 14 comes into close contact with the partition plate 4

14 4 It is possible to cope with a wide range of changes in water pressure due to the natural deformation of the body, and even if the water E suddenly rises, the valve for the port 11 Since the repulsion force of the seat 14 gradually changes over a wide range from a small state to a large state, the port 11 collides with the valve seat 14. Four

It can absorb the impact force of the water and prevent water hammer. The thin band 13 formed in the opening 18 of the valve seat 14 may be formed by notching the lower surface of the opening 18 as shown in FIG. 10 (a). Also, as shown in Fig. 2 (b), the opening 18 may be formed by providing a 蘀 19 over the entire upper surface 7C of the peripheral edge. When the water passing through the water flows backwards, a washer 17 is installed to prevent the water from flowing out of the metering chamber 27 through the valve opening 10. An impeller that is loosely fitted to a rotating shaft 22 that is fixed to a position that is slightly offset to the side just below 0 and that is arranged parallel to the control rod 40. Is rotated in one direction by the reduction gear group 21 and is transmitted to the cam wheel 4 1 via the friction clutch 50 to rotate the cam wheel 4 1. Reduction gear group 2 1 is the rotation of impeller 20 Two gears 28 and 29 having different numbers of teeth are coaxially and integrally stacked on the rotating shaft 2.2 and the rotating shaft 23 arranged in parallel with the rotating shaft 22. A plurality of wheel shaft gears 36 formed together are loosely fitted, and the large and small gears 28, 29 of the wheel shaft gear 36 loosely fitted to the two rotating shafts 22, 23 are joined alternately. The toothed wheel 37, which is coaxially and integrally connected with the impeller 20 at one end of the impeller 20, is the first wheel 3 of the reduction gear group 21. 8, the tillage of the impeller 20 is gradually reduced by the reduction gear group 21, and the power wheel 41 is transmitted to the side.o The rotating shafts 2 2, 2 3 are at one end. Strength;

And the other end is supported by a support 扳 79, and a partition wall 98 is provided between the impeller 20 and the reduction gear group 21.

It is partitioned from the weighing chamber 27. The friction clutch 50 co-rotates with the clutch grass 51 which is combined with the final gear 24 of the reduction gear group 21 and the water amount setting 30 and the clutch wheel 51. It is composed of a clutch plate 52 that comes into E-contact with the clutch wheel 52 by a spring force, and a disc spring 53 that biases the clutch plate 52 with a spring. The latch plate 52 and the disc spring 53 are set coaxially on the 30 rotating shaft 31. The clutch wheel 51 is mounted on the rotating shaft 31. When the rotation plate 31 is loosely fitted to the rotation itself, it is prevented from falling off, and the clutch plate 52 is fixed to the rotating shaft 31 and is clamped by the disc spring 53. O The friction clutch 50 is in contact with one surface of the latch wheel 51 and has such a configuration. Therefore, the friction clutch 50 is connected to the clutch wheel 51 via the reduction gear group 21. 5 1 to be transmitted to impeller 2 0 Rolling is performed only when the rotating shaft 31 is forcibly stopped from rotating by the means described later, and the friction between the clutch wheel 51 and the clutch plate 52 is caused by friction. As a result, the rotation is transmitted to the rotation shaft 31 as it is, and the rotation shaft 31 stops its rotation. The frictional force acting between the latching wheel 51 and the clutch 裉 52 exceeds the maximum static frictional force, that is, the maximum transmission force), and the frictional force between the latching wheel 51 and the clutch 552 increases. The rotation of the impeller 20 is not transmitted to the rotating shaft 31 because the clutch plate 52 is slipped with the clutch plate 52 so that the rotating shaft 31 can be stopped. Therefore, when the rotation of the blade 20 is transmitted to the rotating shaft 31 via the friction clutch 50, the cam wheel 4 mounted on the rotating shaft 31 is required. Rotate 1 o mo Car 41 is shown in Figure 7. 6

In this manner, the control rod 40 is formed in a disk shape having a cam surface 44 having a V-shaped groove on a part of the periphery, and the rear end of the control rod 40 on the circumference including the V-shaped depression. I also show der to弹接, one of the inclined surfaces of the V-蓐and stop the water surface 4 8, the continuous passing of the water surface ⁴ 9 a portion of flat surface違読the other inclined surface or the inclined surface of this If you are, of stopping the water surface 4 continuously passed Kiriryoudori water 4 5 and to have ₀ or a flat surface of the rest of successive 8 water 4 9 such to the inclined surface central portion及beauty Limited through water 4 5 Water stop surface 4 8

O The control rod 40 is provided with a spring 42 fixed at one end to a flange 39 provided at the center in the longitudinal direction. It is biased by a spring and moves back and forth with the rotation of the camshaft 41, and the position is regulated by 0 at the tip to regulate the position of 0. The water volume is set at 0 (zero). 0 is fixed to the rotating shaft 31 and rotates together with the rotating shaft 31, and a cam surface

Limited water flow scale with predetermined water volume displayed corresponding to 4 4 3 2,

A mark 33 indicating the water stop position and a scale 34 indicating the continuous water flow are sequentially shown. On the other hand, as shown in FIG. 7, the cam vehicle 4.1 has a substantially DZ-shaped engaging portion provided on the rotating shaft 31 in a substantially 3Z4 circular engaging hole 76 provided in the center thereof. The rotation shaft 31 and the rotation of the cam 41 are provided with a play at a predetermined angle a between the rotation shaft 31 and the rotation of the cam wheel 41. The play at this angle a is set to be equal to or greater than the rotation angle between the front and rear ends of the water stop surface 48 of the cam surface 44, or more.o A limited amount of water supply, that is, water supply is provided. If you want to automatically stop the water supply when the specified amount of water has been reached since the start, first set the water flow rate ^ 30

\ ¾? ATlO Set the water scale 32 to the mark 9 on the box 1 so that the desired water volume is obtained. O At this time, see Fig. 9 (a), (b) and (c). Thus, the linear portion of one of the engaging holes 76 and the linear portion of the engaging portion 35 of the rotating shaft 31 are engaged with each other, so that the water wheel 41 is set together with the water amount dial 30. Although rotating, the reduction ratio of the reduction gear group 21 is tens of thousands or more, which is very large, and is large enough to transmit rotation from the final gear 24 to the impeller 20. In order to take the power, the clutch wheel 51 and the clutch plate 52 and the force; the water amount is set by slitting. O In other words, when setting the limited flow scale 3 2 to the mark 9 of the bank 1 in order to supply the limited amount of water, the friction clutch Impeller 20 does not rotate due to the action of 50 Since the water volume is set at the same time as the fan 30 and the cam wheel 41 only rotate and are rotating in the opposite direction, it is possible to adjust the scale 32 to the desired water volume. It is easy, for example, if you set the water flow rate (i.e.) and turn 30 too far, or if you change the set value for a limited amount of water, you can easily adjust the set value. In this way, when the scale 32 is to be supplied with a limited amount of water in accordance with the desired amount of water, the impeller 20 is rotated by the water flow, and the rotation is decelerated. Set the amount of water and the amount of water ^ 1) and rotate 30 and. At this time, as shown in Fig. 8 (b), the rear end of the control rod 40 is in contact with the limited water flow surface 45 of the cam wheel 41, and as the impeller 20 rotates. As shown in FIG. 9 (d), when the rotating shaft 31 rotates, the drum wheel 41 does not rotate at first, and the engaging hole 7-6 of the cam wheel 4 1 and the rotating shaft 3 1 do not rotate.

In this case, the rotation is started later, and some cause is caused until the engagement portion 35 reaches the engagement hole 76, for example, the engagement hole 76 and the rotating shaft. If the cam wheel 41 rotates due to the frictional force acting between it and the arc surface of 31, one end of the control rod 40 is provided on the limited water flow surface 45 of the cam surface 44. Abuts the concave portion 54 to brake the rotation of the cam wheel 41, and the linear portion of the engaging portion 35 of the rotating shaft 31 contacts one linear portion of the engaging hole 76. The rotation of the power wheel 4 1 is stopped until the rotation of the power wheel 4 1 is completed, and after the rotating shaft 31 is rotated to a predetermined position, the cam wheel 4 1 is co-rotated with the rotating shaft 3 1. One end of 40 is pushed out of the recess 54 and advances to the inclined water stop surface 48, where the spring 42 presses the water along the slope of the water stop surface 48. The control rod 40 slips, and Fig. 9 (e) and As shown in the figure (ί), the cam wheel 41 is moved within the play angle a between the engaging portion 35 of the rotating shaft 31 and the engaging hole 7.6 of the cam wheel 41. The control rod 40 turns back suddenly and the control rod 40 retreats rapidly, and as shown in Fig. 8 (a), the control rod 40 closes the valve port 10 to stop water supply. On the other hand, continuous water supply can be performed by setting the water flow rate and turning 30 in the water stop position and rotating it in the opposite direction to the case of limited water supply. That is, when the water amount setting wire Jb 30 is rotated in a continuous water supply, as shown in FIG. 8 (e), the control rod 40 whose rear end abuts on the continuous water flow surface 49 is formed. Moves forward to open the valve port 10 and start water supply o In this state, the impeller 20 rotates by the water flow and receives the power from the cam wheel 4 1 Tries to rotate the control rod 40 further forward, but the control rod 40 is biased rearward.

,: The rear end pushes the continuous water flow surface 49 to make the car 41 tilled in the opposite direction, so that the forces of the two balance and the car 41 stops. o In other words, the angle of inclination of the continuous water flow surface 49 is set so that the forces acting in the two opposite directions are balanced. Then, the impeller 20 which rotates by receiving the water flow 20 X. The reciprocating wheel 41 has a friction clutch 50 force to be transmitted to the arm; As a result, only the impeller 20 and the reduction gear group 21 continue to rotate under the water supply without being transmitted to the mowers, so that the area of the continuous water surface 49 during continuous water supply is desired. The amount by which the tip of the control rod 40 protrudes into the water stop chamber 15 can be continuously adjusted, and the amount by which the valve port 10 is closed by the port 11 becomes variable. As a result, during continuous water supply, the amount of water supply per unit time can be adjusted in the same way as ordinary water supply. Recess 5 5 is the amount of water set in the water supply position of the medium amount of water to have you at the time of continuous water supply ^ I §) 3 0 of click operation Ru Der also to I row ₀ here in the amount of water set ^ I A) When the water is continuously cultivated, the rear end of the control rod 40 comes into contact with the flat part of the power surface 44, and the impeller 20 rotates as the impeller 20 rotates. Since the camshaft 41 will rotate, the water amount is set to prevent this from happening. The stopper 77 provided on the inner peripheral surface of the screw 30 is screwed 9 7 It is locked by the lid 96 that protrudes from the lid 96 that is attached to the cank 1, and the rotation of the cam wheel 41 is set to the water flow rate. Both stops are stopped. O In addition, this stopper 77 and the stopper 78 are used to set the amount of water. Till the water supply In this case, the water flow is set and the water is stopped at the predetermined rotation amount, and the maximum set water amount at the time of limited water supply can be determined. When setting 30) is operated, the continuous water supply does not accidentally shift to the limit water supply, and vice versa. It is a projection to reduce the contact area between the cam wheel 41 and the lid 96 so that it can rotate smoothly on one side.o In the above embodiment, the water is stopped from the limited water supply state. When shifting to the state, the control rod 40 retreats rapidly, but when the retraction speed is too fast, the control rod 40! 11 may suddenly block the valve port 10 and cause a water hammer, and in order to prevent this, it is necessary to slow down the retreat speed of the control rod 40. There is shown an example in which the ^^^ :! pot 43 is employed as the speed control means of the control rod 40, and the ^^^: L port 43 has oil-like interior. A control rod 40 is fixed to a piston 101 which is filled with a liquid having viscoelasticity and moves back and forth in the ^^^ pot 43, and is attached to the piston 101. A pore 100 communicating the front and the back is provided, and when the piston 101 moves, the liquid in the pump pot 43 passes through the pore 100 through the pore 100. Moves toward the opposite side of 101, and due to its viscous resistance, piston

The movement speed of 101 is reduced, and as a result, the movement speed of the control rod 40 linked with the piston 101 is also reduced, thereby preventing water hammer. In the figure, 80 is a hose connection pipe,

It is designed to be screwed into the outlet 3 of the link 1 three times. It becomes a tube-shaped hose connection pipe.
