Embodiment 1
[0096] In Comparative Example 1, the O-ring supporting the control valve body was made of hexafluoropropylene-vinylidene fluoride copolymer (FKM) (hardness 70°, rebound rate 14%). Noise generation was investigated under the same conditions as in Comparative Example 1. The results are shown in Table 1.
Embodiment 2
[0098] Noise generation was examined under the same conditions as in Example 1 except that the compression ratio of the O-ring 10 in Example 1 was set to 3.3%. The results are shown in Table 1.
Embodiment 3
[0100] Such as Figure 6 As shown, the arrangement of the O-ring 10 in Example 1 was changed from the intermediate point P to the side of the hot water inlet A (in the area F), and the noise was investigated under the same conditions as in Example 1. produce. The results are shown in Table 1.
