Abstract

1. Device for the automatic closure of sewers (1) in case of backflow, the closure means of which is a ball (2) that is rigidly connected to one side in the sewer (1) and inwardly bulged when without pressure, with a backflow alarm device (10), a source of pressure and automatic pressure control means and where the backflow alarm device (10) is a pot (16) which is screwed on a threaded socket leading into a sewer (1) and containing a float (17) that is contacting a ram (18) which is led out of the pot and is connected to a control valve (8), the ram (18) having a collar (22) at the inside of the pot, characterized in that the source of pressure is an air reservoir (13) with a pressure gage (14) and an air pump (15) delivering into the air reservoir (13), that there is a sealing (23) on the collar (22) of the ram (18) sealingly contacting the cover (9) of the pot (16) if the ram (18) is lifted by the float (17) and that the ram (18) of the backflow alarm device (10) is led with clearance in such a way out of the cover (9) of the pot (16) that the air in the pot (16) can escape until the sealing (23) is contacting the cover (9).
