Disclosed is an air intake manifold including a heat exchanger built into its body and including at least two ducts for supplying and removing heat-exchange liquid, the ducts extending through the wall of the body of the manifold with a liquid-tight seal and an airtight seal, which are distinct and mutually offset along the longitudinal axis of the relevant duct being created on each of the ducts. The unit creating the liquid tight seal is arranged between the relevant duct and a circulation pipe connected to the free end of the duct. The unit creating the airtight seal is positioned between the relevant duct and the body of the distributor. A leakage path associated with the liquid-tight seal is created between the latter and the airtight seal.

Intake manifold with in-built heat exchanger

Disclosed is an intake distributor for an internal combustion engine that includes an integrated heat exchanger. This exchanger includes a support plate that ensures its rigid mounting in the distributor and peripheral seal that form an essentially continuous circumferential airtight barrier between the exchanger and the distributor, peripherally dividing the interstitial volume into two. The subdivision plane of the interstitial volume is perpendicular in relation to the plane of the support plate, and the peripheral seal consist of two complementary components that are connected to one another and made integral with the exchanger.

Intake distributor with an integrated heat exchanger

The present invention relates to a valve device for regulating a fluid, particularly a gaseous fluid, in a conduit portion, comprising a valve body fixed to a support spindle extending transversely into said portion and mounted with the ability to rotate therein, said conduit portion comprising, on either side of said spindle, opposing internal steps forming two bearing surface portions for corresponding edge parts of said valve body, in the closure position thereof, each step extending substantially over approximately half of the internal circumference of the conduit portion in the region of the mounting position of the support spindle. Device characterised in that the opposing edge parts of the plate-shaped valve body comprise deformable sealing means for operation thereof in the closure position of said valve body, in the form of two flexible lips extending from said edge parts asymmetrically on either side of said valve body and at an inclination to the plane of the valve body, a first toward the exterior and the second toward the interior.
