A guillotine damper has the framework (11) surrounding a flow path provided with side and bottom guide sections (22,23). The blade (32) has U-shaped channel (36) extending along the top, bottom (22) and sides (23) thereof with its bottom and side sections dimensioned for sliding engagement with corresponding guide sections. The guide and channel sections (26,36) are connected to the framework (11) and blade (32), respectively, in a manner preventing their distortions by thermal expansion forces. |
