摘要： A flow control device including first and second flow control members, first and second actuators, and first and second transmission devices wherein both flow control members are adapted for rotation about a common axis. The first flow control member has a wall portion which defines an aperture aligned with the common axis. The second transmission device includes a shaft member which passes through the aperture for rotation therein. A first end of the shaft member is coupled to the second actuator and a second end of the shaft member is coupled to the second flow control member. The first transmission device includes a first rotary body coupled to the first flow control member and rotatable about the common axis and a second rotary body coupled to the first actuator and rotatable about a second axis offset from the common axis. The first and second rotary bodies are engagable by a mechanism such that rotation of the first rotary body causes rotation of the second rotary body. The second actuator selectively rotates the shaft member thereby rotating the second flow control member about the common axis and the first actuator selectively rotates the first and second rotary bodies, thereby rotating the first flow control member about the common axis.
