A water outlet chamber-type regulating device includes a chamber component having an inlet and an outlet for a fluid to be regulated, and including a member for regulating the flow, the member having a valve component translatingly movable and configured to close a passage cross-section between the inlet and the outlet, and is rigidly fixed to a control shaft. The chamber component includes at least one opening formed in its lateral wall, and the control shaft carries a second closing component, which is integral in translation with the shaft and is positioned on the shaft and has a shape that is configured to regulate the flow of water passing through the opening as a function of the regulation of the flow in the region of the passage cross-section.

Regulating device of the water outlet chamber type

The present invention relates to a multifunctional module for an internal-combustion engine, forming a structural assembly and incorporating the functions of cooling the exhaust gases, regulating the re-injection of the exhaust gases and regulating, at least in part, the circulation flows in the cooling circuit of said engine, said structural assembly being in the form of a constructional and functional unit intended to be fitted to the engine block and incorporating, on the one hand, at least a portion of an exhaust gas recirculation circuit and a heat exchanger for cooling said gases and, on the other hand, at least a portion of the engine cooling circuit, with at least the water-outlet housing, multifunctional module characterised in that the heat exchanger has a tank arranged in the region of an end of the constructional and functional unit and made from a synthetic thermoplastic material.

Multifunctional module for an internal-combustion engine

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.

Intake manifold or distributor for the thermal engine of a vehicle and production process thereof

The present invention has for its object an intake manifold or distributor with several pipes. Intake manifold or distributor ( ), particularly of thermoplastic material, obtained by the assembly of at least two previously produced constituent parts ( and ) and comprising several intake pipes ( ) formed with said manifold or distributor, characterized in that each intake pipe ( ) is at least partially, and preferably totally, constituted by the coaction of at least one wall portion ( ) of at least one of its constituent parts ( ) with the structural insert ( ) mounted in one of said parts ( ) before their mutual assembly, held in position between them after their assembly and forming at least a portion of the wall of the pipe ( ) in question.
