Abstract: An HVAC (heating, ventilating and air conditioning) damper includes a series of pivotal damper blades that are opened by an air pressure differential across opposite sides of the damper. In some embodiments, a fan discharging against the damper blades provides the necessary air pressure to open the damper. To control how far the damper opens, an actuator moves a variable position abutment that obstructs the damper blades to limit how far they can pivot in the open direction. The position of the abutment is infinitely adjustable to provide the damper with infinite adjustment over a range of open positions. In some embodiments, the abutment applies a unidirectional torque to the damper blades regardless of whether the damper is opening or closing.

Abstract: A conductor feedthrough is provided for allowing an electrical conductor, cable, wire, etc., to be passed through a wall of a pressurized vessel (e.g., a compressor vessel forming part of a refrigeration or air conditioning system) while maintaining a hermetic seal within the vessel and providing resistance to mechanical stress imparted on the conductor. The feedthrough comprises a first casting formed on a portion of a conductor, a fitting engageable with the first casting and inserted into an aperture in a vessel wall, and a second casting formed on an end of the first casting. The fitting is engaged with the first casting in such a manner as to prevent relative rotational movement between the first casting and the fitting. The feedthrough maintains a hermetic seal within the vessel and locks the conductor in place to provide resistance to mechanical stress and/or torque applied to the conductor.
