Abstract
The assembly is composed of a vacuum pneumatic booster (1), a master cylinder (3) and a reservoir (5) of fluid under low pressure which feeds the master cylinder, and is intended to convert a force exerted on a control pedal into a fluid pressure supplying at least one fluid motor. The booster (1) has at least one chamber connected to a vacuum source via a non-return valve (30). This chamber is connected to the source via a duct (21) formed in the master cylinder (3), the non-return valve (30) being arranged at the outlet of the duct (21). The non-return valve (30) is arranged at the end of a pipe (25), the other end of which is connected in a sealed manner to the duct (21), the non-return valve (30) and the pipe (25) being incorporated into the reservoir (5).
