対偶関係を設定した回動弁の操作装置。 In a device in which the rotary valve body 1 is inserted into a flow path formed in the main body 2 and is pressed against the body side by the pressing force of the spring 3, a rotary valve body 1 coaxial with the rotary valve body 1 is A spring holder 4 is rotatably provided in the main body 2, and a spring 3 is provided between the spring holder and the rotary valve body 1.
The spring retainer 4 is coupled to a cam portion formed on the main body 2 and is interlocked to rotate integrally with the rotary valve body 1. At both ends of the rotation range of the spring retainer 4, this spring retainer The operating device for the rotary valve is such that the cam pair relationship is set so that the spring 3 is most compressed and is in an uncompressed state or a low compressed state in an intermediate region.
