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.
