ABSTRACT:
The present invention is a new type of an electromechanical actuator that combines two rotary outputs from a solitary electrical input into a single molded housing. The actuator comprises an input assembly responsive to an external electrical control source. Preferably, the control source provides a control signal for each valve door to be controlled. The actuator also comprises a first geartrain assembly responsive to the input control assembly and a second geartrain assembly responsive to the input control assembly. The first geartrain assembly includes a first motor responsive to the input control assembly. A first output gear is operably connected to the first motor and a first rotatable output coupler is connected to the first output gear. The second geartrain assembly includes a second motor responsive to the input control assembly. A second output gear is connected to the second motor and a second rotatable output coupler is connected to the second output gear. Preferably, the rotatable outputs are co-axially and concentrically mounted. Methods of rotating output couplers to open and close valve doors are also disclosed.
