DEVICE FOR SEALED CONNECTION BETWEEN TWO CONDUITS

摘要

The invention concerns a device for sealed connection between two conduits (2, 4) at least, comprising a body (6, 8 or 10, 12) housing at least a sealing member consisting of at least a sleeve (14, 16) made of flexible material directly mounted at the end of at least one of the conduits (2, 4) concerned and compressed by the effect of flanging means (2, 4) between them. The invention is characterised in that the flexible material (14, 16) sleeve (14, 16), rubber, silicone or any other polymer is made integral by adhesion resulting from polymerisation or vulcanisation, at the end of at least either one of the conduits (2, 4), said adhesion being obtained by overmoulding said flexible material (14, 16) directly on the previously prepared outer surface of the conduit (2, 4), advantageously the conduit comprises a fold (24) or fitting for anchoring on the conduit (2, 4) the flexible material constituting the sleeve (14, 16), and the sleeve comprises a centring raised part (18, 20) designed to co-operate with a matching raised part (20, 18) provided on a sleeve (16, 14) integral with the other conduit (4, 2). The invention is particularly applicable for cooling (air conditioning), in chemistry, hydraulics, and in motor cars.
