Abstract

Disposición de conducción de un fluido, del tipo que comprende una parte central en forma general sensiblemente cilíndrica rodeada a distancia por una envolvente (5) con pared interior sensiblemente cilíndrica, caracterizada porque la parte central está constituida por dos piezas (1, 10) sensiblemente semicilíndricas, en contacto la una con la otra y con la pared interior a lo largo de sus bordes longitudinales (2) opuestos diametralmente, teniendo cada una, unos alerones radiales (3 subíndice 1 a 3 subíndice 5) que estén dispuestos al tresbolillo, cuyos bordes tocan la pared interior y que se extienden solamente por una fracción del arco comprendido entre los bordes longitudinales.
