Abstract

The dosing of solutions of chemicals into flowing water of a water pipe is effected, according to the invention, by a piston-cylinder pump (1, 2) which is driven, via a transmission (17) and eccentric(s) (29), by a hydraulic motor (3) through which the stream of the water main (23) is flowing. In order to avoid excess dosages, a valve (4) opens a bypass (22) when a predetermined pressure drop at the hydraulic motor (3) is exceeded. The solution flows from the reservoir (11) which is mounted onto an outlet spigot (13), into a chamber (10) and via a conduit (14), the dosing pump (1, 2) and a conduit (15) to the infeed point (16) on the water pipe (23). When a minimum filling level in the chamber (10) has been attained, a valve actuated by a float (8) opens a conduit (30) through which water reaches the chamber (10) from the water pipe (23). Thus liquid is always present in the chamber (10), so that it is not possible for any crystallisation to occur, for example when the reservoir (10) is emptied completely. <IMAGE>
