Abstract (en)
[origin: WO02079653A1] The invention relates to a hydropneumatic pressure reservoir (1) with a housing formed from at least two housing shells (3, 5) which may be connected together. At least the end region of the one housing shell (5) comprises an outwardly-extending, funnel-like guide surface between the free end thereof and a sealing element for bringing together the both housing shells (3, 5). At least one 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 region of the pressure reservoir may thus be achieved.
