Abstract

La présente invention concerne un collecteur d'admission avec lequel, bien que des tubes métalliques soient utilisés comme tubes de ramification du collecteur d’admission et bien qu’un collecteur et une bride soient préparés comme des éléments distincts, on obtient simultanément une précision dimensionnelle, une réduction de coût et une aisance de modification de la conception du collecteur suffisantes. Le collecteur d’admission est constitué de tubes de ramification (11) destinés à former des trajets d’air, une bride (12) permettant de relier une extrémité de chaque tube de ramification (11) à une culasse d’un moteur et un collecteur (13) pour relier les autres extrémités des tubes de ramification (11). Le collecteur (13) et la bride (12) et/ou les tubes de ramification (11), qui sont des tubes métalliques, sont formés d’une seule pièce par moulage d’insert.
