ABSTRACT:
An improved vent operator for controlling the position of an edge opening vent in the roof of a recreational vehicle or the like is disclosed. The vent operator is coupled to an electric motor, manual jamb or crank or the like, and comprises a set of reduction gears and drives two sector arms which raise or lower the vent cover. The gear reduction is accomplished by spur gears which have good mechanical properties. The cost of the entire apparatus is minimized by making the gears from pressed metal, the sector arms from stampings and the housing from castings. The result is a reliable vent operator that can be produced economically in commercial quantities.
