The hot and cold mixing faucet 2 is exposed from the wall surface,
The temperature of the hot water is adjusted to an appropriate temperature by operating the temperature adjustment handle 18. By operating the flow rate adjusting handle 19, the discharge flow rate from the water discharge section can be adjusted. The pressure regulating valve 4 and the branch fitting 5 are embedded in a concave portion provided on the wall surface, and only the push button portions of the push button valves 9, 10, and 13 are exposed.

When it is desired to discharge water from the fixed shower fitting 8 while the push button valves 9, 10, 13 and the pressure regulating valve 4 are closed, when the push button 91 of the first push button valve 9 is pressed, the first push button valve 9 is opened. The valve body 92 opens, and the open state is held by the thrust lock mechanism. When the first push button valve 9 is opened, the pressure on the secondary side is reduced, so that the pressure in the pressure chamber 41 of the pressure regulating valve 4 is decreased, the pressure regulating valve body 42 is opened, and the hot water mixed by the hot and cold water mixing faucet 2 is supplied. The water is discharged as a shower from the fixed shower fitting 8 through the pipe 3, the pressure regulating valve 4, the branch fitting 5, the first branch portion 6, and the first connecting pipe 7.

To stop the water discharge from the fixed shower fitting 8, when the push button 91 of the first push button valve 9 is pressed again, the valve body 92 of the first push button valve 9 closes, and the closed state is set by the thrust lock mechanism. Will be retained. When the first push button valve 9 is closed, the secondary side pressure increases, so that the pressure in the pressure chamber 41 of the pressure regulating valve 4 rises and the pressure regulating valve body 42
Is closed, and the shower discharge from the fixed shower fitting 8 is stopped.

FIG. 2 shows the details of the first push button valve 9. An on-off valve 94 is incorporated in the first valve body 93. The on-off valve 94 is provided between a valve hole 97 surrounded by a valve seat 96 provided in a partition wall 95 formed inside the first valve body 93 and a communication hole 98 formed downstream thereof and communicating with a fixed shower fitting side.

By pressing the push button 91 in this manner, the valve body 92 is seated on the valve seat 96 as shown in FIG. 9A and the valve body 92 is closed as shown in FIG. The valve can be switched to a valve-open state separated from the seat 96.

The spring constant of the coil spring 104 for urging the valve body 92 toward the valve seat 96 is determined by the on-off valve 94
Immediately after it is closed, it contracts due to a pressure increase due to the generation of a water hammer on the upstream side. Thus, when the pressure rises on the upstream side after closing the on-off valve 94, the valve body 92 separates from the valve seat 96 and communicates with the flow path toward the fixed shower fitting as shown in FIG. It is possible to make the water supply leak and release the rise in pressure to the atmosphere. That is, in this example, the opening / closing valve 94 provided with the opening / closing means has a pressure buffering function, and the opening / closing means and the pressure buffering means are integrally formed. The second push button valve 13 and the third push button valve 17 have the same structure.

The packing 43 provided around the valve hole 42 has an inner diameter capable of stopping water as a seal when the sliding portion 51 is inserted.

When the open / close valve 94 such as the first push button valve 9 is opened and the mixed water is supplied from the hot / water mixer tap, the mixed water passes through the valve hole 42 in the pressure regulating valve 4 and passes through the branch fitting 4.
Side, and the flow velocity before and after the restriction of the valve hole 42 increases, and the pressure around the tip of the cone 50 of the control valve body 45 decreases. For this reason, the internal pressure of the pressure chamber 49 communicating with the communication path 48 also decreases, and the control valve body 45 is held at the position shown in the figure by the urging force of the spring 47, and the mixed water is supplied from the valve hole 42 to the branch fitting 4 side. Is continued.

When the on-off valve 94 such as the first push button valve 9 is closed, the internal pressure of the flow passage on the branch fitting side rises. At this time, since the flow of the mixed water in the pressure regulating valve 4 also stops, the vicinity of the valve hole 42 also becomes equal to the internal pressure of the branch fitting 4, and the pressure rise after valve closing is increased by the communication path 48 of the control valve body 45 through the pressure chamber. 4
9 as well. Therefore, the internal pressure of the pressure chamber 49 rises, causing the spring 26 to contract, whereby the control valve body 45 moves to the valve hole 42 side, the sliding part 51 comes into contact with the packing 43, and the flow path is shut off. You.
