<p>The multilayer structure (30) having rotational symmetry, comprises a radially inner layer, which is waterproof, able to resist the aggression of the fluid and constituted by a rubber composition, a system for crosslinking by a peroxide comprising a crosslinking co-agent, a reinforcing layer overlying the inner layer made of a textile reinforcement, and a radially outer layer to withstand the external environment of the structure. The gaseous fluid is conveyed in a motor at a temperature and a pressure of greater than 200[deg] C and 1 bar respectively. The multilayer structure (30) having rotational symmetry, comprises a radially inner layer, which is waterproof, able to resist the aggression of the fluid and constituted by a rubber composition, a system for crosslinking by a peroxide comprising a crosslinking co-agent, a reinforcing layer overlying the inner layer made of a textile reinforcement, and a radially outer layer to withstand the external environment of the structure. The gaseous fluid is conveyed in a motor at a temperature and a pressure of greater than 200[deg] C and 1 bar respectively. The rubber composition is made of fluorocarbon elastomer. The composition further comprises a reinforcing filler made of carbon black. The external layer is made of silicone elastomer so that the structure is devoid of intermediate layer for rubber coating for adhering the outer layer to the inner layer. The cross-linking co-agent has a quantity of: 1-3 pce, where pce is parts by weight per 100 parts of elastomer, for a quantity of reinforcing filler of less than 15 pce and for a mass rate (66-69%) of fluoride in each of elastomer; or 1-6 pce for a quantity of reinforcing filler of greater than 15 pce and/or for a mass rate (66-69%) of fluorine in each of the elastomer. The multilayer structure forms: a decoupling flexible connector having an axially central part (34), which is wavy and/or bent and ends axially by connecting two ends (32) to the air intake system, where the connection is able to support all three-dimensional displacements of the turbocompressor; and a bellows having many peaks separated between each other by troughs to form peripheral ripples (36) projecting radially outwards. An independent claim is included for a system for the admission of air in a motor having turbocompressor of an automobile vehicle.</p> |
