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.
A flow control device comprising first and second flow control members, first and second actuators, and first and second transmission devices, both flow control members being adapted for rotation about a common axis, the first flow control member having a wall portion defining an aperture aligned with said common axis, the second transmission device comprising a shaft member passing through the aperture for rotation therein, a first end of the shaft member being coupled to the second actuator and a second end of the shaft member being coupled to the second flow control member, the first transmission device having a first rotary body coupled to the first flow control member and rotatable about said common axis and a second rotary body coupled to the first actuator and rotatable about a second rotation axis offset from said common axis, said first and said second rotary bodies being mutually engageable by an engagement mechanism extending therebetween such that a rotation of the second rotary body causes a rotation of the first rotary body, wherein the second actuator selectively rotates the shaft member freely within the aperture of the first control member thereby rotating the second flow control member about said common axis and wherein the first actuator selectively rotates the second and first rotary bodies thereby rotating the first flow control member freely about said shaft member and said common axis.
A flow control device comprising first and second flow control members, first and second actuators, and first and second transmission devices, both flow control members being adapted for rotation about a common axis, the first flow control member having a wall portion defining an aperture aligned with said common axis, the second transmission device comprising a shaft member passing through the aperture for rotation therein, a first end of the shaft member being coupled to the second actuator and a second end of the shaft member being coupled to the second flow control member, the first transmission device having a first rotary body mounted coaxially with said common axis and coupled to the first flow control member, the first rotary body having a first toothed sector, and a second rotary body coupled to the first actuator with a rotation axis offset from said common axis, the second rotary body having a second toothed sector, said first and said second toothed sectors being mutually engageable such that a rotation of the second rotary body causes a rotation of the first rotary body, wherein the second actuator selectively rotates the shaft member freely within the aperture of the first control member thereby rotating the second flow control member about said common axis and wherein the first actuator selectively rotates the second and first rotary bodies thereby rotating the first flow control member freely about said shaft member and said common axis.
