PURPOSE:To make it possible to use an adjusting valve for mixture and division, by forming two valve elements which commonly use one rotary shaft in one valve such that the inner one of valve elements is rotated together with a valve rod while the other outer one thereof is free from rotation of the valve rod within a predetermined angle rage. CONSTITUTION:A valve element 2 which is integrally incorporated with a valve rod 8, is disposed in a valve element 3 to form a double valve element structure. A 90 deg.-sector-like shape stopper 7 is provided to one part of the valve rod 8, being projected therefrom, and then a boss 8 in a shape such as, for example, a semi-circular shape, integrally incorporated with the valve element 3 is arranged in the vicinity of a valve rod hole of the valve element 3. Thus, design is made such that the relationship therebetween is suitably selected so that the valve element 2 is rotated always together with the rotation of the valve rod 8, and therefore, only when the boss 6 is made abut against the stopper 7, the valve element is rotated. |
