Sealed connection assembly for connecting vacuum system on wall of structure of brake amplifier of motor vehicle, has cylindrical sealing joint comprising elastic retaining unit cooperating with connection stop integrated to end fitting

摘要

The assembly has a connector (9) comprising an end fitting (91) that cooperates with a hollow cylindrical sealing joint (5) fixed inside a circular connection orifice in a sealed manner. The joint comprises a sealing unit i.e. circumferential flange (74), and an elastic retaining unit (520) cooperating with a connection stop (524) integrated to the end fitting. The joint comprises an inner lip (51) and an outer lip (52) that is arranged adjacent to the inner lip. The inner and outer lips are packed in a wall of a structure (1), where the outer lip comprises a retaining unit. Independent claims are also included for the following: (1) a brake amplifier comprising a low pressure chamber (2) a method for connecting a vacuum system on a brake amplifier by a connection assembly.
