Abstract

Patente de Invenção:<B>"CONDUTO FLEXìVEL"<D>. Um conduto flexível (10) é formado em parte com uma tira helicoidalmente enrolada de metal (11) que fornece resistência à pressão de ruptura. A tira possui um rebordo ou gancho de borda anterior (22) e um gancho de borda posterior (23) que engatam e entrelaçam quando a tira é helicoidalmente enrolada. A seção trasversal da tira possui um perfil em formato de Z assimétrico com uma seção de corpo principal intermediária às bordas de tira. Um vale a montante (26) é formado entre o gancho de borda anterior
