Abstract
A guillotine damper has the framework surrounding a flow path provided with side and bottom guide sections. The blade has U-shaped channel sections extending along the top, bottom and sides thereof with its bottom and side sections dimensioned for sliding engagement with corresponding guide sections. The guide and channel sections are connected to the framework and blade, respectively, in a manner preventing their distortions by thermal expansion forces.
