Abstract

Condotto flessibile antivibrante in cui un manicotto metallico ondulato conformato a soffietto in modo da risultare elasticamente deformabile è rivestito esternamente da una calza in maglia metallica e termina all'interno di due testate tubolari rigide accoppiate solidali per deformazione plastica con rispettive estremità del manicotto, a pizzicare corrispondenti estremità della calza esterna; la sezione trasversale del condotto è appiattita, per esempio presentando forma ovale o ellittica; tra rispettive ondulazioni del manicotto a soffietto è presente un passo maggiore in corrispondenza di tratti del manicotto prossimi alle testate, in modo da determinare una maggiore rigidità di tali tratti, e l'altezza delle ondulazioni in corrispondenza dell'asse maggiore della sezione (ovvero di quell'asse di simmetria della sezione trasversale del manicotto in cui questa presenta l'ingombro massimo) essendo differente dall'altezza delle medesime ondulazioni in corrispondenza dell'asse minore delle sezione (ovvero di quell'asse di simmetria della sezione trasversale del manicotto in cui questa presenta l'ingombro minore).(Figure 2 e 3)
