Abstract

The invention relates to a dosing device for introducing an additive (A) in to a main liquid flow (L) in a conduit comprising a reciprocating differential piston pump ( 2 ) which is used for collecting and dosing the additive (A) from a container ( 1 ) and comprises a first inlet ( 7 ) for receiving the main liquid flow which ensures the pump actuation, a second inlet ( 8 ) for collecting the additive and an outlet ( 9 ) for mixing the additive and the main liquid. The inventive device comprises a Venturi ( 10 ) disposed in the conduit and the pump ( 2 ) connected in parallel position with respect thereto, wherein the first inlet ( 7 ) of the pump is connected to the Venturi input ( 11 ) and the outlet thereof is connected to the Venturi throat ( 12 ).
