Abstract: A functional module integrates a distributor with a plenum and several pipes that form a common attachment and connection plate, a fuel rail, and a holding part for ensuring the locking in position of the fuel rail. The functional module (1) is characterized in that it consists of an interlocked and nested arrangement that includes the distributor (2), the fuel rail (7), and the holding part (9), with the fuel rail (7) being held between the holding part (9) and the distributor (2), and in that the holding part (9) and the distributor form by cooperation a longitudinal receiving housing with the possibility of locking the fuel rail (7) whose introduction opening is defined between an arrangement of feet (10) of the holding part (9) and the plate (5) of the pipes (4).

Abstract: A distributor incorporates a heat exchanger mounted in the interior space of the distributor while being made integral with the wall of the body of the distributor by at least one side flange. The distributor is characterized in that its two constituent parts (5 and 5?) are joined by welding opposing joining edges (6 and 6?), the edges (6, 6?) being connected physically to one another in an airtight manner along a contact area (7) in the form of a peripheral continuous band, surrounding the outer periphery of the flange (4), and mechanically connected, in a localized and discontinuous way, to the flange (4) by engagement at through openings (8) and/or at deformed or radius-chamfered areas of the latter. A process of manufacturing the distributor is also described.
