Abstract

In known apparatuses, highly polluted water, for example sewage, can lead to the soiling and even clogging of the deaerating valve (5, 6). Furthermore, in known apparatuses, in the event of excess pressure in the sewage conduit, the deaerating valve is kept closed to an increased degree, since the valve-closing body (5) is connected to a float (2). In order to avoid the foregoing, the pressure in the sewage conduit acts on the valve-closing body (5) as a compensating force (7-10) to the float closing force. Furthermore, the deaerating valve (5, 6) is placed in a narrow neck portion (12) of the housing (1, 12, 14), so that solids in the sewage are largely kept away from the deaerating valve. <IMAGE>
