A seal ring 25 is held in an annular groove provided on the inner peripheral surface of the through hole 21a. A pilot passage 26 communicating with the water discharge passage 13 is formed so as to be continuous with the through hole 21a.

  The control shaft 3 shown in FIGS. 3, 4, and 5 is in a state where water does not flow from the back pressure chamber 24 b to the pilot flow path 26 when the seal portion 30 a contacts the seal ring 25. At this time, water flows into the back pressure chamber 24b through the small hole 23, the water pressure in the back pressure chamber 24b increases, and the main valve 20 comes into contact with the valve seat 51d to be in a water stop state. When the control shaft 3 is raised in the axial direction so that the recess 30b or the tapered surface 30c faces the seal ring 25, water flows from the back pressure chamber 24b to the pilot flow path 26, and the water pressure in the back pressure chamber 24b decreases. Then, the main valve 20 moves away from the valve seat 51d, and water flows from the inflow passage 51c to the water discharge passage 13.

In the temperature adjustment unit 4, the control shaft 3 and the rotation unit 41 are rotated by rotating the temperature adjustment operation unit 40, and the temperature adjustment valve unit 42 is moved in the axial direction. As the temperature control valve 42 moves in the axial direction, the upper end surface 42a of the temperature control valve 42 is moved closer to or away from the water side valve seat 14a and the lower end surface 42b is moved closer to or away from the hot water side valve seat 14b. The temperature adjustment unit 4 mixes water and hot water flowing in from the water side inlet 11a and the hot water side inlet 12a when the temperature adjustment valve part 42 approaches or separates from the water side valve seat 14a and the hot water side valve seat 14b. Change the ratio and adjust the water discharge temperature.

  The flow rate adjustment unit 5 moves the control shaft 3 in the axial direction by rotating the flow adjustment operation unit 53. The flow regulating valve unit 52 is moved using the pilot flow generated by the back pressure chamber 24 b communicating with the pilot flow path 26 according to the movement position of the control shaft 3. The flow rate adjusting unit 5 adjusts the discharged water flow rate flowing through the water discharge path 13 when the opening degree of the flow control valve unit 52 is determined corresponding to the movement position of the control shaft 3. The flow adjustment valve unit 52 does not need to be directly operated manually by the flow adjustment operation unit 53 and is moved using a pilot flow, so that the operation load on the flow adjustment operation unit 53 can be reduced.

  The water stop portion 6 presses the water stop button 60 by a push operation and pushes the control shaft 3 in the axial direction toward the water discharge passage 13, whereby the back pressure chamber 24 b of the flow control valve portion 52 communicates with the pilot flow path 26. Make sure that the water stops. The water stop part 6 holds the water stop button 60 in the water discharge position or the water stop position by the cam part 61.

  The channel switching unit 7 rotates the channel switching operation unit 70 integrally with the switching valve unit 71 at the lower part of the housing 10, thereby switching the position of the water outlet 13 a provided in the switching valve unit 71.

Since the switching valve unit 71 is provided on the downstream side of the temperature control valve unit 42 and the flow control valve unit 52, water and hot water are agitated in the water discharge channel 13, and water having a temperature closer to the temperature expected by the temperature adjustment. Can be discharged from the water outlet 13a.

  The valve device 100 can be miniaturized by having functions of temperature adjustment by the temperature adjustment unit 4, flow rate adjustment by the flow rate adjustment unit 5, and flow path switching by the flow path switching unit 7. Moreover, the valve apparatus 100 can perform the water stoppage by push operation by providing the water stop part 6. FIG.

  The water discharge passage 13 is provided so as to extend downward in the axial direction from the position where the temperature adjustment valve portion 42 and the flow adjustment valve portion 52 are provided. Since the switching valve portion 71 is provided at the lower end portion of the water discharge passage 13 and does not overlap the temperature adjustment valve portion 42 and the flow adjustment valve portion 52 in the radial direction, the temperature adjustment valve portion 42 and the flow adjustment valve portion.
