Abstract
The invention relates to a pressure-limiting device designed to be installed in a system comprising a first line () and a second line () that can comprise pressurised oil, as well as comprising a discharge and/or booster line (). The limiting device is characterised in that it comprises means () forming two valves, each associated with one of the two lines and adapted to open in the event of an overpressure above a pre-determined threshold on the associated line, so as to discharge the corresponding overpressure towards the discharge and/or booster line, said two valves comprising a common support stem () that operates in traction under the action of at least one spring defining a pressure corresponding to the pre-determined threshold. The invention also relates to a hydraulic assist system and to a vehicle comprising such a device.
