Abstract (en)
[origin: EP0570739A1] The drainage system operated at subatmospheric pressure is composed of a subatmospheric-pressure source (12), of a collection line (14, 16) connected thereon and of a plurality of connection lines (22) which are connected to said collection line and can be respectively shut off by a scavenging valve (24). In order to stabilise the subatmospheric pressure available at the connection lines and thus to ensure the function of scavenging valves controlled in dependence on pressure, the invention provides that the collection line (14, 16), passing between the connection lines (22) and the subatmospheric-pressure source (12), is laid in an inclined manner and is dimensioned such that part of its inner cross-section remains free, even if it is subjected to peak loading. <IMAGE>
