A valve regulating device intended to regulate the circulation of a fluid in the region of an opening, said device consisting of a pivoting valve body, of an annular support body integrating two opposing bearings mounting said valve body in a rotational manner, and of a control pin, wherein said valve body may be displaced in rotation between a totally open position and a closed position, in which it rests against the annular seat provided by the support body; the support body is provided with a seal with a first extending functional segment and a second extending functional segment having protruding lateral extensions, for example in the form of ribs, on the face of the support body that bears against the edge of the opening, said extensions also being interconnected by intermediate joining portions, which also extend in a protruding manner over the bodies of the two opposing bearings so as to provide a continuous peripheral seal around the opening when the regulating device is mounted on said opening.

Valve regulating device and intake manifold comprising at least one such device

The present invention relates to an intake manifold or distributor for a thermal engine constituted by at least two parts () 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 characterized in that it comprises an additional attached piece () comprised, on the one hand, of a main body forming a support and fitting plate and, on the other hand, of pipe portions () produced in one piece with said body () and defining at least the inlet orifices () of said pipes (), said attached piece () being positioned and, if applicable, fixed, prior to assembly of said at least two parts () forming said manifold or distributor on or in one of these parts.
