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.

Abstract: Disclosed is a hydro damper for absorbing pressure oscillations and/or acoustic vibrations in systems which are operated by means of pressurized fluids. The inventive hydro damper is provided with a housing (1) having a leading dimension which defines a longitudinal axis (3) of the housing, a connection block (5) fluidically connecting the damper housing (1) to the corresponding system, and a linking device (7, 47, 49) which is assigned to the connection block (5) so as to mount the connection block (5), and consequently the damper housing (1), on the system in selected rotational positions relative to an axis of connection (41) that runs perpendicular to the longitudinal axis (3) of the housing.

Abstract: A hydropneumatic pressure reservoir (1) forms a housing from at least two housing shells (3, 5) connected together. At least the end region of the one housing shell (5) includes an outwardly-extending, funnel-like guide surface between its free end and a sealing element for bringing together the two housing shells (3, 5). At least on elastic sealing element (41) is provided on at least one retaining surface for generation of a tensioning force on the boundary region (21) of the membrane (13). A simplified construction with improved sealing in the critical connection of the pressure reservoir is achieved.
