<p>The invention relates to an arrangement in a vacuum system for waste water and the like. In such arrangements it is a problem to convey the waste water in a simple and reliable manner from the sanitary installations into the pipeline system, in which vacuum prevails, for being further conveyed to a collecting place. The arrangement according to the invention comprises a vertically movable container (10) in which the waste water is collected. By causing the weight of the liquid to surmount a spring force and a force originating from the vacuum in the pipeline system, an outlet for the water is opened, which is thus discharged into the pipeline system.</p> |
