摘要

The present invention relates to an intake manifold or distributor for a thermal engine constituted by at least two parts (1, 1') assembled together, in particular two parts made from thermoplastic material assembled by vibration welding and comprising an intake or plenum chamber connected, for fluidic communication, to intake pipes opening into the chamber. Intake manifold or distributor for a thermal engine characterised in that it comprises an additional attached piece (4) comprised, on the one hand, of a main body forming a support and fitting plate and, on the other hand, of pipe portions (6, 6') produced in one piece with said body (5) and defining at least the inlet orifices (6, 6') of said pipes (3), said attached piece (4) being positioned and, if applicable, fixed, prior to assembly of said at least two parts (1, 1') forming said manifold or distributor on or in one of these parts.
