The invention relates to a leakage device for the depletion of a diaphragm accumulator when the vehicle so equipped is not in use. This device determines a permanent leakage of the liquid to a low-pressure reservoir with a predetermined rate of flow. According to the embodiment of the invention shown in the attached drawing, the device comprises a rod (150) mounted in the plunger (110), and the leakage path is defined between the rod (150) and a narrowed zone (131) of an axial passage (132) located inside the plunger. Preferably, the plunger (110) comprises a bore (126) and passages (127, 134) in communication with the inlet port (104) and the outlet port (106), and a core (130) received in the bore (126), the axial passage (132) being formed in the core (130), and the rod (150) being mounted in the core (130). The invention is used for the braking of motor vehicles.
