Abstract: The invention relates to a flush for toilets containing a container with an air vessel, a connection piece for the network, a connection piece for the flush, a valve housing comprising a control device and an injector tube. A suction device is joined to the injector tube. The flush is characterized in that an air-refilling opening (7) is arranged in the valve housing (6) underneath the control device (10) that is suitably accommodated in the valve housing (6). A jet tube (15) is arranged above the control device in order to deviate the flushing water. An air-introducing chamber (5) is arranged in and/or next to the jet tube (15).

Abstract: A conduit having two substantially parallel, flexible and continuous flow tubes fixedly mounted at their ends to a centrally positioned housing The ends of each flow tube positioned proximal to one another and to the center of gravity formed by the shape of the flow tube. Each flow tube substantially forming a "B" shape having a first loop, a connecting portion and a second loop. The first and second loops being symmetrical with respect to the connecting portion and extending laterally from the center of gravity at a greater distance than the displacement of the connecting portion to the center of gravity. The flow tubes being oscillated in opposing modes at the connecting portion so as to produce a measurable Coriolis reaction force by the fluid on the flow tubes.
