Claims

[Scope of utility model registration request]

A valve box is provided with a chamber having a spherical inner wall surface, and two or more inlet portions and two or more outlet portions each communicating between the chamber and the outside, the outer surface of which is connected to the chamber. A valve body having a spherical valve part formed in a matching spherical shape coaxially disposed on a rotating shaft is housed so that the spherical valve part is disposed inside the chamber, and A pressure guiding valve, wherein a pressure guiding path is formed in the valve portion to selectively communicate or close the introduction portion and the outlet portion depending on the rotational position of the valve body.
