Abstract

Ein hydropneumatischer Druckspeicher mit einem in einem Speichergehäuse (1) angeordneten, bewegbaren Trennelement, das einen ersten Arbeitsraum, vorzugsweise Gasraum (7), von einem Fluidraum (5) als zweitem Arbeitsraum separiert und durch eine Membran (3) aus einem flexiblen Werkstoff, insbesondere einem Elastomer, gebildet ist, wobei sich am Speichergehäuse (1) eine einen Zugang zum Fluidraum (15) bildende Gehäuseöffnung (15) befindet, deren Durchgang durch eine in eine Freigabestellung und eine Schließstellung überführbare Ventilanordnung steuerbar ist, die einen an einem Flächenabschnitt der Membran (3) befindlichen Ventilkörper (29) besitzt, der bei Annäherung an einen an der Gehäuseöffnung (15) befindlichen Ventilsitz (33) die Ventilanordnung in die Schließstellung überführt, wobei die Ventilanordnung eine bei der Schließstellung einen begrenzten Durchstrom durch die Gehäuseöffnung ermöglichende Bypassanordnung aufweist, ist dadurch gekennzeichnet, dass der Ventilkörper (29) zur Bildung der Bypassanordnung an seiner dem Ventilsitz (33) zugewandten Fläche (34) zumindest einen Vorsprung (37) aufweist, der gegenüber dem Ventilsitz (33) einen den Durchstrom ermöglichenden Abstandhalter bildet.
