Abstract
The invention relates to a hydraulic reservoir in particular a membrane reservoir, with a gas inlet body (12) which may be connected to parts of the reservoir housing and which comprises at least one mounting surface (28) for an elastically flexible separating element (16), which separates two chambers arranged within the reservoir housing from each other. The separating element (16) comprises a edge reinforcement (30) formed by material thickening to give a fixing edge for that part with the corresponding mounting surface (28) of the gas inlet body (12). Failures at the position of the fixing of the separation element to the hydraulic reservoir are avoided, despite high loading of the separating element under working conditions for the reservoir, whereby the edge reinforcement (30) is provided with a convex guide surface on the side thereof facing the gas inlet body (12) in contact with the corresponding mounting surface (28), which is at least partly concave in embodiment to match said unit.
