When the pressing portion on the inner circumference is pressed, the intake valve opens and the air tank opens. Air is supplied into the dry suit. When exhausting, push the inner pressing part to open the intake valve,
The exhaust valve is opened by pressing the pressing portion on the outer circumference. Then, the air in the dry suit passes through the gap of the exhaust valve and is ejected to the exhaust hole, and the pressure of the air passing through the gap at high speed is lowered (Bernoulli's theorem). The air in the dry suit is forcibly exhausted together with the air in the air tank.

In the No. 9 publication, a natural exhaust valve is used as the exhaust valve, so air in the vicinity of the exhaust valve can be exhausted,
There is a problem that the air accumulated in other parts cannot be exhausted. Therefore, the diver himself moves in the water,
It is necessary to guide the air that has accumulated in other parts to the vicinity of the exhaust valve to exhaust it, and it is difficult for beginners to guide the air that has accumulated in other parts to the vicinity of the exhaust valve, and it is not possible to exhaust it sufficiently. It was That is, there is a problem that the air in the dry suit does not escape well for a beginner, which makes it difficult to dive.

The pressure by the inner surface of the exhaust valve cover 14 is released, and the lower valve 161 and the upper valve 162 both move from the suction gap 104 to the valve body 7.
It is pushed up by the air flow flowing between the middle cylinder 8 and the middle cylinder 8 and flowing into the ventilation hole 93 of the middle cylinder presser 9. The air inside the dry suit is exhausted from the exhaust port 201 of the exhaust cover 20 to the exhaust valve box 1
3 is sucked out to the plurality of exhaust ports 143 of the exhaust valve cover 14 through the plurality of discharge holes 136 in the lower surface 131 of
The air in the dry suit can be exhausted to every corner. When the exhaust is finished, the exhaust operation is stopped by releasing the exhaust button 63.

かに行える。When tightening due to water pressure becomes tight due to the depth of diving, the intake button 53 of the intake valve 1 is pressed against the elasticity of the compression coil spring 33, so that the valve rod 3 descends and the small diameter portion 31. Reaches the insertion hole 48 of the large diameter portion 32. Then, the air in the air tank from the inlet passage 11 of the intake valve 1 is dried from the small diameter portion 31 through the insertion hole 48, the outlet passage 12 of the intake valve 1 and the air supply hole 191 of the intake cover 19 as described above. Air is supplied into the suit. Therefore, the optimum air pressure can be quickly adjusted according to the diving depth.

The air intake button 53 is pressed against the elasticity of the compression coil spring 33 to supply air into the dry suit. Further, during ascent, the air in the dry suit expands as the depth becomes shallower. Therefore, the expanded excess air is exhausted by pressing the exhaust button 63 of the exhaust valve 2 in the same manner as described above.
Since it is exhausted by forced exhaust, the exhaust speed is fast, and it is easy to adjust the levitation while keeping the levitation speed constant.
