The structural unit, made from portions of two pipes forming part of two circuits in which different fluids, especially gases, circulate, and including a flow regulator, has a first pipe portion extending partly round a second pipe portion, with the two portions sharing a common wall. The unit is made from two assembled components (8, 9), each injection-molded in one piece from thermoplastic material(s) with optional mineral fiber reinforcement, and incorporating a connector (5') for the flow regulator assembly (4). The first component (8) has a surface (10) that forms part of the intermediate wall between it and the second component, which has couplings (6, 6') for adjoining components. The flow regulator has a membrane (16), a spring (17) and a cap (18). |
