ABSTRACT:
A dosing device is provided for introducing small doses of a liquid contained in a first chamber into a second liquid flowing in a second chamber. The device includes a body traversed by a bore which fluidly connects the chambers to one another and in which slides a push pin mounted on a sliding member and a follower pin mounted freely between the push pin and an abutment bar attached to the sliding member. The sliding member reciprocates parallel to the axis of the bore whereby the follower pin is pushed in one direction by the abutment bar and in the opposite direction by the push pin. A space separating the follower pin from the push pin constitutes the dosing chamber which is displaced between the first and second chambers.
