In addition, the spindle 15 has a temperature setting handle 17 as an operating part at the outer end and an adjusting valve body 18 at the inner end, and the adjusting valve body 18 is formed in a cylindrical shape to form a first cylindrical shape. Slidingly inserted into the through hole 9 of the partition 4, the front end face corresponds to the second valve seat 11 and the rear end face corresponds to the first valve seat 14.

Thus, the regulating valve body 18 moves away from the other valve seat (14 or 11) when operating in the direction approaching one valve seat (11) or (114). And the fluid of the first chamber 1, that is, the cold water, is formed between the first valve seat 14 and the rear end face of the control valve body 18 via the inside of the control valve body 18 to form a second partition wall ( 5 flows into the third chamber 3 from the through hole 10, and the fluid of the second chamber 2, that is, the hot water, passes between the second valve seat 11 and the front end face of the control valve body 18. It flows into the third chamber 3 from the through hole 1.

Therefore, the ratio of the hot water and the cold water flowing into the third chamber 3 is a change in the distance between the control valve body 18 and the first and second valve seats 14 and 11 according to the movement of the control valve body 18. Is adjusted accordingly.

That is, the 1st, 2nd valve seat 14 (11) and the control valve body 18 comprise the control valve a.

The third chamber 3 described above is provided with two opening and closing valves of a water metering valve (b) and a manual opening and closing valve (c), and through each of these two opening and closing valves (b) and (c). The same discharge portion 19 is contacted, and the discharge portion 19 is connected with a bath water discharge port 20, and the water metering valve b has a quantity setting cam 21 and a deceleration value array 22. And a water metering function portion b ₁ having a vane 23 and an opening and closing valve portion b ₂ having a valve seat 24 and a valve body 25 corresponding thereto. The valve body 25 of the opening / closing valve part b ₂ is fitted to the inner circumferential surface of the lid 26 closing the opening provided in the main body A so as to face the valve seat 24 with each other in a piston shape. The pressure chamber 27 isolated from the 3rd chamber 3 is formed behind it.

The pressure chamber 27 is always in contact with the primary side of the opening / closing valve portion b ₂ via a small hole 32 provided in the valve body 25, and is provided at the center of the valve body 25. It is also possible to communicate with the secondary side of the opening / closing valve part b ₂ via the if valve d. That is, the valve body 25 of the opening / closing valve part b ₂ and the valve body 25 front side are provided, and the guide 25 has a pressure chamber 27 and a valve part b for opening and closing in the center part 25 '. ₂ ) A valve hole 29 ′ of the relief valve d is installed so as to communicate the secondary side of the valve, and a relief valve body 28 for opening and closing the valve hole 29 ′ is provided with an opening / closing valve portion ( b ₂₎ of the valve body 25 closely hayeoseo the relief valve seat 29 formed on the back surface be biased by a spring 30 to close the ball valve 29 'is baebi in the pressure chamber 27.

The relief valve body 28 has a valve shaft 31 on the front surface thereof, and is formed in an approximately umbrella shape. The valve shaft 31 slides the valve hole 29 'freely to open and close the valve portion ( b ₂ ) is extended to the secondary side and the front end thereof is pressed against the outer circumferential surface of the water quantity setting cam 21 by the spring 30.

When the relief valve d is opened on the main surface of the valve shaft 31, the cold water in the pressure chamber 27 is discharged to the secondary side of the opening / closing valve portion b ₂ through the valve hole 29 ′. When the relief valve d is opened to some extent at the front end protruding to the secondary side while the groove 43 is provided in the axial direction, it is brought into contact with the guide 25 'of the valve valve 25 for opening and closing. A hanging ring 31 'that restricts sliding of the valve shaft 31 is provided.

The groove 43 has the secondary side of the pressure chamber 27 and the opening / closing valve part b ₂ even when the hanging ring 31 'contacts the guide 25' of the opening / closing valve 25. It is formed to reach to the bottom of the hanging ring (31 ') so as to communicate.

The quantity setting cam 21 is provided with a notch 21a on a part of the circular cam centered on the rotation axis, and a curved surface of which the bottom surface of the notch 21a is continuous with the surface of the circular cam 21a. is formed in, and be secured to the cam shaft 33 a rotatably to carol to the secondary side of the movable valve (b ₂₎ for being disposed on the outlet side of the valve portion (b _2), closing the relief valve (d) In this case, the valve shaft 31 of the relief valve body 28 is opposed to the notch 21a.

One end of the cam shaft 33 is interlocked with the handle shaft 36 via teeth 34 and 35 that interlock with each other, and the handle shaft 36 extends outward of the main body A. Install the quantity setting handle 37 at the front end.

The other end of the camshaft 33 can transmit the rotation of the camshaft 33 in accordance with the rotational operation of the quantity setting handle 37 to the tooth difference 22n to the final tooth 22n of the deceleration value sequence 22. However, on the contrary, the rotation of the final gear 22n transmitted by the decelerating gear train 22 was frictionally contacted so as to be transmitted to the camshaft 33.

That is, the final gear 22n of the reduction gear array 22 is not attached to the cam shaft 33 by the attachment screw 44 inserted into the center of the cam shaft 33 so as to be rotatably attached to the cam shaft 33. (44) Between the head and the gear 22n, the plate spring 46 is clamped by a bush 45 through the bush 45, and a washer 47 is inserted between the gear 22n and the cam shaft 33. The end gear 22n and the camshaft 33 are frictionally interlocked and contact | connected by the press pressure of the said dish-shaped spring 46. As shown in FIG.

That is, the rotation of the camshaft 33 due to the rotation operation of the handle 37 is not transmitted to the washer 47 and the disc spring 46, but the frictional force to the final tooth 22n of the transferee is the decelerating tooth row 22. It is not as powerful as reverse operation, and the washer 47 and the disc spring 46 cannot slip so that rotation can be transmitted to the final gear 22n, on the contrary, it is transmitted by the deceleration tooth row 22. Rotation of the final gear 22n is comprised so that it may transmit to the camshaft 33 through the washer 47 and the disc spring 46. As shown in FIG.

On the other hand, the first gear 22a of the reduction gear array 22 engages with the gear 39 provided in the blade shaft 38, and the blade shaft 38 is located downstream of the cam 21 for quantity setting. Thus, the rotor 33 is axially rotated on the secondary side of the valve portion, and the blade car 33 is attached and fixed thereto.

The vane 23 is provided with a plurality of wing pieces to close the secondary side of the valve portion, and is rotated by flowing water flowing through the secondary side of the valve portion.

Then, the foreign material metering valve b rotates the quantity setting handle 37 to rotate the quantity setting cam 21 in the direction of the arrow in FIG. 1 via the handle shaft 36 and the cam shaft 33. The valve surface 31 of the relief valve body 28 is pushed up by the cap surface 21b to open the relief valve d, and the water of the pressure chamber 27 flows out to the secondary side of the valve portion. As the valve shaft 31 rises again, the valve body 5 of the opening / closing valve part b ₂ is pushed up and closed by the ring-shaped ring 31 'via the cylindrical guide 25'. The valve portion b ₂ is opened, and the mixed water adjusted to the appropriate temperature of the above-described control valve a is flowed from the third chamber 3 to the discharge portion 19.

At this time, the water in the pressure chamber 27 is discharged to the secondary side of the opening and closing valve portion b ₂ by opening the relief valve d, and the pressure chamber 27 is connected to the outside for opening and closing valve portion ( b ₂ ), ie equal to atmospheric pressure.

Therefore, after opening the relief valve d, the valve shaft 31 is pushed up to the cam shaft 21 only by the elasticity of the spring 30, so that the valve shaft 31 moves upwards lightly.

Moreover, the force which presses the valve body 25 of the opening-closing valve part b ₂ to the opening direction of a valve is also removed, and the valve body 25 is the holding ring 31 'of the valve shaft 31. It is smoothly pushed up by the opening and closing valve part (b ₂ ) is opened.

And at the same time as opening of the movable valve (b ₂₎ for passing through the movable valve (b ₂₎ for, by mixing water flowing into the discharge part 19 ikcha 23 rotates, and its rotation speed reduction gear column It slows down via 22 and is transmitted to the cam 21, and the cam 21 automatically continues to rotate.

In addition, since a small amount of mixed water flows into the pressure chamber 27 through the small hole 32, the water flows out of the relief valve d, so that the cam 21 rotates once to release the relief valve body 28. The opening state of the opening / closing valve part (b ₂ ) is continued until the valve shaft 31 of the s) falls into the notch 21a of the cam 21 and the relief valve d is closed.

That is, when the valve shaft 31 of the relief valve body 28 falls into the notch 21a of the cam 21, the relief valve d is applied to the relief valve body 28 by the spring 30. The valve immediately closes due to the pressurizing pressure of the spring, and the valve body 25 of the opening / closing valve part b ₂ is applied to the pressure chamber 27 from the small hole 32 by the shot pressure of the spring 30 described above. As the volume of the pressure chamber 27 increases due to the inflow of the mixed water, it descends gently to close the part close to the valve seat 24.

When the opening / closing valve portion b ₂ is closed and the flow of water on the secondary side of the opening / closing valve portion b ₂ is stopped, the rotation of the blade wheel 23 is naturally stopped, and thus the rotation of the cam 21 is also stopped. .

The opening time of the opening / closing valve portion b ₂ is approximately equal to the opening time of the relief valve d, and the opening time of the relief valve d, that is, the opening time of the opening / closing valve portion b ₂ . In other words, the amount of discharged water is determined in accordance with the setting of the rotation angle of the cam 21 by the operation of the quantity setting handle 37.

That is, the cam 21 is rotated in the direction of the arrow by the handle operation to set the required angle, and the water flow flowing through the opening / closing valve part b ₂ to the discharge part 19 rotates the blade wheel 23. When the cam 21 is rotated again in the direction of the arrow and rotated once in the initial state, the notch 21a of the cam 21 faces the valve shaft 31 of the relief valve body 28 again. If the rotation angle of the cam 21 rotated by the handle 37 is large, the opening time of the opening / closing valve part b ₂ , that is, the discharge time is short, and if the rotation angle is small, the discharge time is long.

When the opening / closing valve b ₂ is closed and the flow of the mixed water to the discharge portion 19 is stopped, the rotation of the blade wheel 23 is naturally stopped, and thus the rotation of the cam 21 is also stopped.

The manual opening / closing valve (c) described above is used when it is discharged continuously or frequently discharges and stops repeatedly without using the water improvement valve (b). By the rotation operation of the operation handle 41, the axial direction is advanced, the valve seat 42 is approached and doubled to open and close the valve.

In addition, this manual opening / closing valve (c) is not necessary in the hot / cold water mixing faucet provided with the above-mentioned water measuring valve (b). Next, the second embodiment shown in FIGS. 5 to 6 will be described. In this embodiment, the adjusting valve a is not connected to the handle 17 for directly setting the temperature of the adjusting valve a. The handle 17 is in communication with the secondary spindle.

That is, the tubular cover 51 is screwed into the opening 12 of the main body A, and the bus pins 50 are rotatably installed by inserting the cover 51 into the opening 51. The liner 13 attached to the inner circumferential surface of the lid 51 is attached to the top surface of the lid 51 to prevent movement in the axial direction.

In addition, the inner end of the buspin pin 50 is provided with a bleeding blood 52 in the axial direction, and an end portion of the spindle 15 screwed into the liner 13 is inserted in the bleeding blood 52. On the outer circumferential surface of the spindle 15 and the inner circumferential surface of the bus pins 50, splines 53 are engaged with each other.

The liner 13 described above is fitted to the through hole 9 of the first partition wall 4 across the first chamber 1, and the first chamber 1 and the liner 13 in the first chamber cross section. It has a communication hole 54 for communicating.

And the front end of the adjustment valve body 18 slides the opening end freely, and respond | corresponds to the 2nd valve seat 11, The 1st valve seat 14 is installed in the middle part of the liner 13, and is adjusted. It corresponds to the rear end surface of the valve body 18.

In the present embodiment, the first chamber 1 is connected to the cold water supply pipe and the second chamber 2 is connected to the hot water supply pipe in the same manner as in the first embodiment.

In this embodiment, the discharge section has two outlets 56 and 57 for the bath for connecting the bath water discharge port 20 and for the shower for connecting the shower hose 55, and the opening / closing valve is for this bath. And a switching valve (e) for selectively opening and closing the shower.

The switching valve (e) is bath valve (e ₁₎ and consists of a shower valve (e ₂₎ for, respectively, the valve (e _1), the valve seat 58 and 59 of (e ₂₎ the third chamber ( 3, the valve body 60, 61 is provided on the primary side of the valve seat 58, 59, respectively, and the valve seat 60 and 61 correspond to these valve seats. A spring 63 that presses against (58) and (59) is mounted with pressure.

The valve bodies 60 and 61 have protrusions 64 projecting in the relieved state in the valve seats 58 and 59 when the valve is closed in the central surface side which is placed in the seat. In addition, in one of the valve bodies and in the figure, the valve body 60 of the bath valve e ₁ has a hole 65 penetrating through the central portion thereof, that is, the valve body 61 of the shower valve e ₂ . Although the diameter is slightly larger than the hole 65 described above, the bleeding blood 67, which has a ruler portion 66 with a slight diameter at its inlet, is provided on the same axis as the hole 65.

The rod-shaped valve guide 69 holding the head 68 enlarged at the front end is inserted into the hole 65 of the valve body 60 of the bath valve e ₁ freely, and the shower valve e The enlarged head 68 at the front end of the valve guide 69 is slidably inserted into the bleeding blood 67 of the valve body 61 of ₂ ).

The valve guide 69 is connected to the spindle 70 at the rear end thereof, and the spindle 70 is screwed into a cover 71 for closing an opening provided in the body A. It extends outside of A) and has a handle 72 at its outer end.

The opening and closing valve (e) closes two valves (e ₁ ) and (e ₂ ) for a normal bath and a shower, but when the handle 72 is rotated in a clockwise direction, for example, the spindle 70 moves forward to provide a bath valve ( It presses the valve body 60 of e ₁₎ hayeoseo and opens the valve ₍₁ e) as shown in Fig fifth.

Therefore, the mixed water in the third chamber 3 flows to the bath outlet 56 and is discharged from the bath water outlet 20 connected to the outlet 50.

At this time, the spring 63 is compressed by the forward movement of the valve body 60 so that the valve body 61 of the shower valve e ₂ is pressed into the valve seat, so that the valve e ₂ is reliably. It is closed.

When the handle 72 is rotated in the counterclockwise direction in this state, the spindle 70 retreats so that the enlarged head 68 at the front end of the valve guide 69 moves the valve body of the shower valve e ₂ . The shower valve e ₂ is opened by hanging on the hanging portion 66 of the urine bleeding 67 of 61 and moving the valve body 61 in the direction in which the valve is opened.

Accordingly, the mixed water in the third chamber 3 flows to the shower outlet 57 and is supplied to the shower from the sour hose 55 connected to the shower outlet 57.

At this time, as the spring 63 is compressed in accordance with the movement of the valve body 61, the valve body 60 of the bath valve e ₁ is pressed against the valve seat 58 so that the valve e ₁ is surely closed.

Next, FIG. 7 shows another embodiment of the part of the control valve a, in which the opening 12 is provided in the third chamber 3, and the spindle 15 closes the opening 12. As shown in FIG. The screw 51 was inserted into the main body A, and the penetrating hole 10 of the second partition 5 was inserted across the third chamber 3 in a sorry state.

The spindle 15 is provided with a hole 80 which communicates with the inside of the adjustment valve body 18 by penetrating it radially through the portion crossing the third chamber 3. Therefore, the fluid of the first chamber 1 is discharged in the adjusting valve body 18 and via the hole 80 of the spindle 15 between the adjusting valve body 18 and the first valve seat 14. The fluid of the second chamber 2 flows in between the main surface of the through hole 10 and the spindle 15 via the second valve seat 11 and the adjusting valve body 18. Flows into the third chamber (3).

In FIG. 8, the other embodiment of the adjustment valve (a) part is shown similarly to FIG. 7, The 1st valve seat 14 is attached to the 1st partition 4 of the 1st chamber 1 side, and the 2nd valve is shown. Since the seat 11 is formed in the wall of the 2nd space 5 of the 3rd chamber 3 side, detailed description is abbreviate | omitted.

In addition, hot water may be introduced into one of the first and second chambers 1 and 2, and cold water may be introduced into the other.

In the four embodiments shown in the drawing, all of the control valve body 18 and the spindle 15 are integrally formed, but these can be formed separately, and the structure of the opening / closing valve is arbitrary.

In addition, the opening / closing valve (b) (c) (e) and the discharge part 19 can also be provided separately from the main body A. FIG.

The present invention is configured as described above, and one of the fluids in the first chamber and the second chamber flows into the outer surface of the valve body of the control valve, and the other fluid flows directly into the mixing chamber through the inside of the control valve. Since there is only one opening and closing valve downstream, the flow path from the control valve to the opening and closing valve is shortened linearly so that it does not become a resistance of the flow of hot and cold water.Therefore, there is no pressure drop between the hot and cold water, so both flow smoothly. The mixing ratio of the cold water and the hot water adjusted as is also very convenient to use because it can match the mixing ratio of the hot water and cold water of the mixed water discharged.

In addition, the adjusting valve body has a cylindrical shape, and the fluid in the first chamber is the third chamber, which is a mixing chamber, via the interior of the adjusting valve body through the gap between the adjusting valve body and the first valve seat, and the fluid in the second chamber is the adjusting valve body. Since it is allowed to flow into the mixing chamber through the gap between the first valve seat and the first valve seat, it is only necessary to match the cylindrical control valve body to the first and second valve seats, and the structure is extremely small, and the first and second chambers The third chamber is installed adjacently, so that the hot water chamber, the cold water chamber and the mixing chamber are installed adjacent to each other, thereby simplifying the structure of the main body and miniaturizing the whole faucet for mixing hot and cold water. The processing is simple and the price is cheap.

In addition, since the third chamber for mixing the introduced hot water or cold water is contacted to the discharge unit via a valve for opening and closing, the valve can be opened with a constant mixing ratio, so that the desired purpose can be achieved.
