The leaf separator includes a pipe part (1) with connections to the downpipe and a discharge outlet (4) directed sideways. The upper wall (8) of the discharge outlet (4) is inclined upwards with an angle ( beta ) which is equal to or larger than the inclined angle ( alpha ) of the lower wall (5) upwards. The side walls (6,7) of the discharge outlet are mainly parallel to each other. The side walls of the outlet can diverge sideways from the centre of the pipe part. A lower section of the pipe part is of even thickness or converges upwards towards the grid (9). |
