Abstract

Keksinnön kohteena on palon- ja savunrajoitin (10). Palon- ja savunrajoitin käsittää kanavan (11) tai vastaavan ja sen sisäpuolella sulkupellin (12), joka on kierrettävissä palotilanteessa aukiasennosta kanavaa (11) sulkevaan asentoon jousen (17) jousivoiman vaikutuksesta. Palon- ja savunrajoitin käsittää varustukset (100) lämpösulakkeelle (19), jolloin lämpösulakkeen (19) avulla on sulkupelti (12) viritettävissä jousen (17) jousivoimaa vasten aukiasentoon kanavassa (11). Lämpösulake (19) tulee sijaitsemaan sulkupellin (12) ja kanavan (11) tai muun vastaavan runkorakenteen välillä ja jolloin palotilanteessa muuttuu lämpösulakkeen (19) dimensiot siten, että sulkupelti (12) vapautuu kääntymään kanavaa (11) sulkevaan asentoon jousen (17) jousivoiman avulla. Jousen virityspisteen (D) ja sulakkeen keskinäinen positio on vaihdettavissa palon- ja savunrajoittimen (10) poikittaisakselin (Y) samalta puolelta toisiinsa nähden vastakkaisille puolille. FIG. 1The invention relates to a fire and smoke damper (10). The fire and smoke damper comprises a duct (11) or the like and inside it a closing damper (12), which can be rotated from an open position to a position closing the duct (11) under the influence of the spring force of a spring (17). The fire and smoke damper comprises fittings (100) for a thermal fuse (19), whereby the closing damper (12) can be adjusted against the spring force of the spring (17) in the open position in the duct (11) by means of the thermal fuse (19). The thermal fuse (19) will be located between the closing damper (12) and the duct (11) or other similar frame structure and whereby in a fire situation the dimensions of the thermal fuse (19) change such that the closing damper (12) is released to rotate to a position closing the duct (11) under the influence of the spring force of the spring (17). The relative position of the spring setting point (D) and the fuse can be changed from the same side of the transverse axis (Y) of the fire and smoke damper (10) to the opposite sides. FIG. 1
