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.With a hydraulic system with at least one pump, which optionally supplies the consumer with a flow from a tank is said to be one Solution to be created with the multiple hydraulic Tables with consumers, in particular operating tables, even with defects in the electrical or electronic System can be operated safely, whereby in the defect-free Normal operation ensures comfortable operation should be.

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.

Figure 00000001
This is achieved in that a first delivery path with an electrically operated pump and electrically operated valves and a separate second delivery path with a foot pump and with mechanical valves are provided between the tank and the consumers, with the consumer and the electrically operated valves or changeover valves are arranged in the mechanical valves such that the flow to the respective consumer is provided either by the electrically operated pump or the foot pump.
