Abstract

A vacuum sewer arrangement comprises a bowl connected to a sewer pipe provided with means for establishing, in the sewer pipe, a vacuum sufficient for obtaining efficient sewage transport. There is a normally-closed sewer valve connecting the bowl to the sewer pipe and a control device for controlling operation of the sewer valve to allow discharge of sewage from the bowl to the sewer pipe. There is also an air inlet duct for letting air into the sewer pipe separately from the bowl. For controlling flow of air through the air inlet duct into the sewer pipe, when the sewer pipe is under proper vacuum for effective sewage transport, there is an air inlet valve with means operating it in response to pressure variations in the sewer pipe. Such pressure variations occur when the sewage discharged from the bowl has passed the point where the air inlet duct is connected to the sewer pipe.
This ensures that the air inlet valve operates accurately and securely.
