とを防止することができる。According to the present embodiment, the valve element 163 is
Having a curved surface such that the space B side of the shell is convex (shell,
Since it is formed in the shape of a film) and arranged at the communication port 162, as described above, the communication port 1
62 is opened and closed. Therefore, unlike the invention described in the above-mentioned publication, no float is required, so that even if the communication port 162 is enlarged, it is possible to prevent the steam valve 160 from becoming excessively large.

Since the valve body 163 is opened and closed by the internal water vapor pressure, the valve body 163 is desirably made of a material that is lightweight and has low hygroscopicity.
It is made of a resin (for example, polyphenylene sulfide) having a thickness of about 0.02 g / cm 2 or less per unit area in the opening area of the communication port 162.

2 opens and the differential pressure is 1 × 10 4 Pa (≒ 100 Torr)
The communication port 162 can be reliably closed (sealed) even with the following differential pressure.

円錐テーパ面１６１ａとの接触面圧が高まるので、連通
口１６２をより確実に閉じることができる。As a result, the pressure in the first space A is reduced to the second pressure.
When the pressure is higher than the pressure on the space B side (when a pressure difference that closes the communication port 162 is generated), the shell-shaped depression (shell-shaped projection) 163b is convex toward the second space B side. since curved such that the curved surface 163a is conical tapered surface 161a
Curved to open to the side. Thus, the contact surface pressure between the curved surface 163a and the conical tapered surface 161a is increased, it is possible to close the communicating port 162 more securely.

Therefore, the curved surface 163a
And the contact surface pressure of the conical taper surface 161a decreases.
It can open the communicating port 162 immediately.
