Abstract
The present invention relates to a multi-valve damper which divides a section of an airflow duct into at least two airflow sections. The damper has a plug body having a proximal end and a distal end. The plug body is adapted to separate a section of an airflow duct into at least two airflow sections. At least two damper blades may be mounted on the distal end of the plug body, each of the damper blades controlling airflow in a respective airflow section. At least one airflow sensor may be provided in each of the airflow sections for controlling the respective damper blades. An actuator mechanism responsive to the sensors may be provided for opening and closing the damper blades.
Claims42
A multi-valve damper for an airflow duct, comprising:
- a plug body having a proximal end and a distal end, said plug body adapted to extend across a section of an airflow duct to separate said duct section into at least two airflow sections;
- and
- at least two damper blades mounted on said distal end of said plug body, each of said damper blades controlling airflow in a respective airflow section.
A method for controlling airflow in an airflow duct, comprising:
- providing a plug body extending across a section of an airflow duct for separating the duct section into at least two airflow sections;
- providing a damper blade at the end of each of said airflow sections for controlling airflow in each airflow section.
