    • A filter for aquarium operating in accordance with the lifting-lowering principle comprises a housing with at least one filter compartment for a filter material, a pump which aspirates water after passing through the filter compartment through a suction conduit and supplies the water back into an aquarium, at least one auxiliary chamber supplied with water and a float-controlled valve device controlling an outlet of the auxiliary chamber and communicating with the suction conduit, an auxiliary housing in which the auxiliary chamber is provided and supplied with water filtered after passing of the filter compartment in accordance with the principle of communicating pipes. A passage which is connected with the suction conduit has a valve opening which is alternatingly closeable and openable by a float-controlled valve closing member of the valve device. In another embodiment, a supply is formed as a passage which passes through the filter compartment and is sealed from the latter and opens in a bottom chamber provided in the housing under a lowermost one of the filter compartments, so that the aspiration of the supplied water is performed from below and from the bottom chamber through the filter compartment upwardly with accompanying filtering.
    • 用于根据升降原理操作的水箱的过滤器包括具有用于过滤材料的至少一个过滤室的壳体,在通过抽吸管道通过过滤室之后抽吸水并将水回送到水族箱中的泵 供给水的至少一个辅助室和控制辅助室的出口并与吸入管连通的浮子控制的阀装置,辅助壳体,辅助室中提供辅助室并且供给经过过滤器之后被过滤的水 隔间符合管道原理。 与抽吸管连接的通道具有可由阀装置的浮动控制的阀关闭构件交替地关闭和打开的阀开口。 在另一个实施例中,供应源形成为通过过滤室的通道,并从其中密封,并在设置在壳体内的底部室内在最下面的一个过滤隔室内打开,从而吸入供水 从下方进行,并从底部室通过过滤室向上进行并伴随过滤。
