ABSTRACT:
The vaccum-operated draining system comprises a vacuum source (12), a manifold (14,16) connected thereto and a plurality of connecting conduits (22) connected thereto which are respectively closeable by a suction valve (24). To stabilize the vacuum available on the connecting conduits, thereby safe-guarding the operation of suction valves controlled in response to pressure, provision has been made that the manifold (14,16) between the connecting conduits (22) and the vacuum source (12) is continuously inclined and is dimensioned such that the inner cross-section thereof also at peak loads, in part, is clear.
