<p>A pipe branch piece (1) for a downpipe in which sewage in the form of a sewage layer (W) can be guided on a wall (11, 20) in a fall direction (F) comprises an upper downpipe section (2) having an inlet opening (3), a diverting section (4) adjoined to the upper downpipe section (2), and a lower downpipe section (5) adjoined to the diverting section (4) and having an outlet opening (6), as well as at least one supply pipe section (7), which in the region of the diverting section (4) opens out into the pipe branch piece (1), wherein the diverting section (4) comprises at least one diverting region (8) and a flow region (12) having a wall (11). The diverting region (8) comprises a diverting surface (10), running along a flow curve or flow line (M) and of curved configuration, for the bundling of the sewage as a jet (S), which flow curve or flow line (M) runs at a first angle (S) with respect to the fall direction (F) and at a second angle (a) with respect to a plane (E) extending through the fall direction (F), wherein, as a result of the two angles (P, a), the curved diverting surface (10), with its flow curve or flow line (M) , is directed substantially tangentially to the wall (11) of the flow region (12).</p> |
