top

111a and 111b are formed. In addition, a partition wall 113 supporting the transfer cylinder 120, which will be described later, is formed in an inner lower region of the storage tank 110, and the partition wall 113 smoothly mixes water on both sides of the partition wall 113 to cool to an appropriate temperature. The partition hole 113-1 is formed.

Second, the transfer cylinder 120 is accommodated inside the storage tank 110, and checks the transfer cylinder body 121, the upper and

discharge ports

111a and 111b of the storage tank 110 and communicate with holes formed in the upper and lower sidewalls of the transfer cylinder body 121, respectively. That is, as shown in Figure 3, the upper discharge pipe 122a is in communication with the upper side wall of the transfer cylinder body 121, the lower discharge pipe 122b is in communication with the lower side wall of the transfer cylinder body 121, The water inside the transfer cylinder body 121 is discharged to the outside at a high pressure and large capacity through the

discharge pipes

122a and 122b and the

discharge ports

111a and 111b.

The piston 123 strokes in the upward or downward direction along the inner wall of the transfer cylinder body 121 between the upper and

lower discharge pipes

122a and 122b to direct water inside the transfer cylinder body 121 to the upper discharge pipe 122a or It discharges through the lower discharge pipe 122b.

That is, in detail, during the upward stroke of the piston 123, pressure is applied to the water contained in the upper end region inside the transfer cylinder body 121 to discharge the discharge port 111a through the upper discharge pipe 122a and the piston 123. At the lower stroke, the pressure is applied to the water contained in the lower end region inside the transfer cylinder main body 121 to discharge the discharge port 111b through the lower discharge pipe 122b.

The upper check valve 124a is opened at the lower stroke of the piston 123, and at the upper stroke of the piston 123, the upper end of the transfer cylinder body 121 is sealed to smoothly water through the upper discharge pipe 122a.
