The storage member 4 is pulled out from the container 1 by the cylinder 17 of No. 3, the pressurized object W is put into the storage space 8 of the storage member 4, and the storage member 4 is pulled out from the container 1 by the cylinder 17.
When inserted into the interior, both ends of the storage member 4 and the inner peripheral surface of the container 1 are sealed, and the introduction gap 9 is removed from the supply path 10.
The ultra-high pressure liquid is supplied into the storage space 8 through the storage space 8, and the air vent 11 is closed. Therefore, the pressurized object W can be pressurized by the pressure of the ultra-high pressure liquid in the storage space 8, which is different from the conventional structure. As there is no threaded part, damage to the container 1 can be suppressed, and in this case, by making the outer diameters of the storage members 4 located in both the seal parts 6 and 7 the same diameter or an approximate diameter, it is possible to prevent damage to the container 1 due to hydraulic pressure. It is also possible to cancel out the axial forces in the seal parts 6 and 7, so that the storage member 4 can be moved into the container 1.
In addition, by making the outer diameter of the storage member 4 on the sealing part 6 side slightly larger than that on the sealing part 7 side as in this embodiment, it is possible to reduce the force required to hold the storage member 4 inside the container 1. The member 4 can be inserted smoothly.
