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