The invention relates to a siphon device or booster with which the speed at which effluent water flows from sanitary facilities to the sewerage may be increased. This siphon device (1) comprises a tank (2) having a liquid feed opening (4) and a liquid drain opening debouching near the bottom thereof, said drain opening being connected to a riser pipe (5) and a drop pipe (7) connected therewith, said drop pipe (7) in turn debouching in a U-shaped pipe portion (8) forming a liquid trap that is open in its position of rest. The tank (2) is relatively shallow and means (21) for boosting the siphoning action are arranged between the tank and the U-shaped pipe portion functioning as a liquid trap. The siphon boost means (21) may comprise an element (22) for guiding the flow of the liquid, configured as a discontinuity in the course of a curved part (6) connecting the riser pipe and the drop pipe. The siphon boost means (21) may also comprise a drop pipe (5) returning parallel to the riser pipe. |
