Abstract (en)
[origin: EP0937830A2] The fluid is feedable to the sub-atmospheric pressure conduit by opening a first suction valve connected to the sewage location. In the sub-atmospheric pressure conduit (18), between the tank and the first suction valve an intermediate tank (10) is arranged, in which a suction pipe (14) leads to the sub-atmospheric conduit for suction of fluid in the intermediate tank. In the intermediate tank is a sensor (40), which dependent upon the fluid collected in the intermediate tank controls a suction valve (20) opening and cutting-off a connection between the sub-atmospheric pressure conduit and the suction pipe. It also controls a connection between the intermediate tank and the atmosphere.
