The present invention relates to a system and a process for assembling a tube in a connecting element, and a housing for a braking assistance servomotor, in a device for controlling braking including such a system. The system for assembling a tube ( ) with a female connecting element ( ) comprising a longitudinal bore ( ) provided with a transversal shoulder ( ), system in which a hollow end portion ( ) of the tube is inserted in the said bore in abutment against its shoulder, is characterized by the fact that the longitudinal wall of the said end portion comprises a zone ( ) deformed by compression between the said shoulder and the remainder of the tube and deformed transversally within the internal wall of the bore to provide mechanical connection and tightness between the tube and the connecting element.

System and process for assembling a tube in a connecting element, and servomotor housing including such a system

A brake booster (,) comprising a housing (,); a diaphragm (,) mounted within the housing to define front and rear chambers (,) within the housing; and a cylindrical component (,) mounted within the housing and having an end (,) which passes through a sealing aperture (,) during installation within the housing to make a seal with the cylindrical component; wherein the cylindrical component has a plurality of fingers (,) extending away the said end, the fingers being circumferentially spaced apart around the end, and the outer surface (,) of each finger being chamfered such that the free ends (,) of each finger lie on a circle having an outer diameter (D,) which is less than the inner diameter (D,) of the sealing aperture prior to installation. Easier installation of the cylindrical component during booster assembly, especially where blind installation is required.
