Abstract
The chamber (A) of the overflow outlet control device (A) has an inner circumferential surface which, when viewed in cross-sectional plan view, is generally in the shape of a volute, for directing material entering the chamber (A) via the circular inlet () at the base portion () tangentially outward towards the discharge outlet (A) located in the side wall (). The top wall region () of the interior wall of the chamber (A), a side wall portion () and base portion () together seamlessly form the chamber (A) which is curved in shape internally. When material flows in use between the inlet () and the discharge outlet (A), and passes through the central chamber (A), it encounters no sharp corners or edges, but just smoothly curved or rounded interior wall surfaces. The top wall region () of the chamber (A) also features a protruding flow control formation () which is joined or formed therewith, and which is arranged to extend into the chamber (A), being directed face towards the inlet () such that in use the flow of material into the chamber (A) via the inlet () directly encounters the formation ().
