Claims

[Scope of utility model registration request]

A rotary valve body that can freely rotate forward and backward within a certain range is housed in a valve chamber in a valve case, and the valve case is provided with an inflow passage communicating with the valve chamber and two outflow passages, and the rotary valve The body is provided with a first passage opening/closing part and a second passage opening/closing part for opening and closing each of the valve chamber side ends of the two outflow passages, and the rotary valve body is at one rotation limit. Sometimes the first flow path opening/closing section is in a fully closed state,
The configuration is such that when the second passage opening/closing part is fully open and the rotary valve body is at the other 9-rotation limit, the opposite state is achieved, and by rotating the rotary valve body between both rotation limits, the first and A two-channel simultaneous flow rate adjustment device configured such that the opening ratio of the second two-channel opening/closing portion gradually increases on one side and gradually decreases on the other.
