Abstract

Die Erfindung betrifft einen Hydrospeicher, insbesondere Kolbenspeicher, mit einem Speichergehäuse (10) und mit mindestens einem darin angeordneten Gasraum (12) und einem Fluidraum (14), die über ein Trennelement (16) voneinander getrennt sind, wobei mindestens einer dieser Räume (12, 14) über eine mindestens ein Schaltventil (28, 30) aufweisende Ventilsteuereinheit (26) mit einem Druckmedium befüllbar oder von diesem zumindest teilweise entleerbar ist und wobei das jeweilige Schaltventil (28) in einer zugehörigen Ventilaufnahme (29) untergebracht ist, das in Bewegungsrichtung des Trennelementes (16) von einer Öffnungsstellung in eine Schließstellung und umgekehrt bewegbar ist,. Dadurch, daß die Ventilsteuereinheit (26) in einem zum Gehäuse (10) eigenständigen Ventilblock (24) aufgenommen ist, daß der Ventilblock (24) eine weitere Ventilaufnahme (31) für ein weiteres Schaltventil (30) aufweist, das eine andere Schaltaufgabe löst, und daß die Ventilaufnahmen (29, 31) im wesentlichen gleich ausgebildet und außermittig der Längsachse (33) des Hydrospeichers angeordnet sind für den modularen Einsatz der als Gleichteile ausgebildeten Schaltventile (28,30), ist ein aufwendiges Leitungsnetz zwischen dem Hydrospeicher und der Ventilsteuereinheit vermieden und Dichtigkeits- oder Leckageprobleme, wie, im Leitungsnetz üblich, können erst gar nicht auftreten.
