Abstract (en)

[origin: EP0829584A2] The arrangement sucks out a liquid from a receptacle (16) in which the liquid can be collected, in order to reach a stagnation pressure, after which the liquid is sucked out through a suction pipe (22). The stagnation pressure acts upon a membrane (36), which operates a first valve (32), which acts upon a first chamber (78) which is at ambient pressure and which is bounded by a control membrane (38), in order to operate a second valve (34) which opens the connection in a third valve between the receptacle and the pipe. All three valves and both membranes are arranged in a common housing. The third valve and its piston (46) are mounted in the housing (12) using a membrane (40) which separates second (86) and third (94) chambers. The latter can be connected to the receptacle and the pipe by the third valve, and the second chamber can be connected to the ambient or suction pressure, via the second valve.
