Abstract: A drainage system is provided that comprises a gully having a circumferential side wall, an outlet and a vortex brake with a vortex chamber having a chamber wall with a peripheral inlet opening and a central outlet opening, the vortex brake being arranged in the gully so that a flow path from the inside of the gully to the outlet leads through the vortex brake, and a drainpipe is connected to the outlet. The vortex brake is arranged in the gully so as to be non-demountable, and the vortex brake is provided with a flushing access having a hose connection.
Abstract: A vortex brake (4) for a liquid drainage system has a vortex chamber (5), an inlet section (6) and an outlet (12), wherein liquid can flow into the inlet section (6), through this into the vortex chamber (5), through this and out through the outlet (12). The vortex chamber (5) has a side wall (9), following a conical face, and a base wall (11). The conical face has a cone axis (10), and the outlet (12) is located at an apex of the conical face. The inlet section (6) has side walls (14) and a bottom wall (15) that extend mutually in parallel in a direction of flow (16) in the inlet section (6), and a ceiling. Said ceiling having a converging ceiling portion, which extends between a first and a second end of the ceiling portion, and which, in said direction of flow, extends converging towards the bottom wall (15).
