Abstract

In a vacuum sewer system the vacuum required for transport of waste material from a waste-producing unit (1) via a sewer valve (2) into a sewer pipe (3) is generated in the sewer pipe (3) by connecting the sewer pipe (3) to a pressure chamber (9) which contains a movable air-impermeable membrane (11). An ejector (8), operated by compressed air, can be used to collapse a bellows-type membrane (11) in the pressure chamber (9) to draw waste material into the sewer pipe (3). Subsequent re-expansion of the membrane (11) can be effected with compressed air or by resilient means (19) to aid in expelling waste material from the sewer pipe (3) into a discharge tube (5). <IMAGE>
