を常に等しくするものである。BACKGROUND ART Conventionally, as this type of automatic pressure regulating valve, there has been one shown in FIG. (For example, JP-A-56-
90175 Publication) In FIG. 2, a cylinder 2 is attached to the main body 1, a hot water side valve seat 3 and a water side valve seat 4 are formed at the open end of the cylinder 2, and a disk-shaped hot water side valve body 5 is formed. A valve body 8 having a valve stem 7 on the water side valve body 6 corresponds to the hot water side valve seat 3 and the water side valve seat 4 from the outside of the cylinder 2, respectively, and the valve stem 7 extends into the cylinder 2 and is connected to the cylinder 2. A screw 10 is secured to a disk-shaped pressure receiving member 9 slidably inserted into the hot water side valve body 5 and the pressure receiving member 9.
The space between them is a hot water chamber 11, and the space between the water side valve body 6 and the pressure receiving member 9 is a water chamber 12. When one valve body (5 or 6) approaches the corresponding valve seat (3 or 4) due to the sliding of the pressure receiving member 9 due to a change in the pressure balance between the water chamber 11 and the water chamber 12, the other valve body (5 or 6) moves away from the corresponding valve seat (3 or 4) to always equalize the supply pressures of hot water and water.

題点を有していた。Problems to be Solved by the Invention However, in the above-described configuration, dust and dirt may be present in the small gap between the cylinder 2 and the pressure-receiving member 9 that slides.
There is a possibility that scale etc. may adhere to it, and the pressure regulating function may deteriorate significantly. Also,
Width of the pressure receiving part 9 can be made large to allow for guidance, since rattling tends to occur in the radial direction with the pressure receiving member 9 as a fulcrum, and the rattling prevents smooth sliding and easily deteriorates the function. Even if
This increases the contact area with the cylinder 2, which not only increases the sliding frictional resistance, but also increases the weight of the sliding parts including the valve body 9, making it easier to prevent slight pressure imbalances. There have been problems in that the response cannot be responded to, and the temperature of the mixed water discharged from the hot water mixing device behind the automatic pressure regulating valve fluctuates.

Next, due to fluctuations in the pressure balance, when one valve body approaches its corresponding valve seat, the other valve body moves away from its corresponding valve seat, resulting in an inversely proportional opening and closing operation. The pressure is always equalized by the blades installed on the shaft.
By rotating the hot water side valve body, water side valve body, and piston, the cylinder is released, and sliding resistance is extremely reduced, improving pressure regulation performance and forcibly eliminating scale adhesion and dirt clogging. This provides stable pressure regulation function.

The two valve bodies 15, 17 and the piston 20 are rotated within the cylinder 16 by the vanes 22, 23 provided in the cylinder 16, thereby causing a self-aligning action, and the two valve bodies 15, 17 and The piston 20 becomes free, so the sliding resistance is extremely small, and the pressure regulating function is significantly improved. At the same time, the valve bodies 15, 17 and the piston 2
0 floats inside the cylinder 16, creating uniform gaps around the circumference. Therefore, leakage of hot water from the piston 20 is reduced, and dirt is less likely to get caught compared to the case where the piston 20 slides on one side even with the same clearance. In addition, scale adhesion and dirt clogging on the sliding surfaces are forcibly removed, and the blades 22 and 23 are attached to the shaft 21.
Since it also serves as a guide means 24 to eliminate vibration, a stable pressure regulating function can be obtained.
