Process for forming an hydraulic connection on a hollow body 10, for example a master cylinder, by fitting an interconnecting piece 24 onto a tubular protuberance 16 projecting outwards from the wall of the body 10. The protuberance has at least one thin-walled part which, when the interconnecting piece 24 has been fitted over the protuberance 16, is flanged outwards against an internal bearing surface 38 of the interconnecting piece 24.

Process for forming an hydraulic connection

The invention relates to a fluid reservoir with two compartments, more particularly for supplying hydraulic fluid to tandem master cylinders, this reservoir more specifically comprising two complementary, superjacent parts connected with adhesive, by thermowelding or by any other equivalent method, a central partition attached to the said parts and running across the longitudinal axis of the reservoir to divide the reservoir interior into two compartments having respective outlet orifices, at least one compartment also having a filler orifice, and the two compartments being interconnected by a transfer passage which extends into both of them and runs parallel to the surface of the fluid in the reservoir and substantially at the maximum level for this fluid. The transfer passage enables the hydraulic fluid to pass from one reservoir compartment into the other when the reservoir is filled with hydraulic fluid. However, it must be designed so that enough fluid is retained in each of the compartments, which are connected to respective chambers of the tandem master cylinder, when the vehicle accelerates or decelerates quite hard or when it is parked on a steep slope.
