Abstract

Mit einem Hydrauliksystem mit wenigstens einer Pumpe, welche über Ventile den Verbrauchern wahlweise einen Förderstrom aus einem Tank zur Verfügung stellt, soll eine Lösung geschaffen werden, mit der mehrere hydraulische Verbraucher aufweisende Tische, insbesondere Operationstische, auch bei Defekten im elektrischen bzw. elektronischen System sicher betätigt werden können, wobei im defektfreien Normalbetrieb eine komfortable Bedienung gewährleistet sein soll.
Dies wird dadurch erreicht, dass zwischen dem Tank und den Verbrauchern ein erster Förderweg mit einer elektrisch betätigten Pumpe und elektrisch betätigten Ventilen und ein getrennter zweiter Förderweg mit einer Fußpumpe und mit mechanischen Ventilen vorgesehen ist, wobei zwischen den Verbrauchern und den elektrisch betätigten Ventilen bzw. den mechanischen Ventilen Umschaltventile angeordnet sind, derart, dass der Förderstrom zum jeweiligen Verbraucher entweder von der elektrisch betätigten Pumpe oder der Fußpumpe bereitgestellt wird.
