Abstract: A process of and a device for the automatic continuous injection of an adjuvant into a fluid in which the adjuvant is injected into the fluid by means of a plurality of syringes of which at any one time at least one is feeding adjuvant to the fluid, the individual syringes being operated in alternating filling and discharge phases, and the pressure in each syringe at the end of the filling phase and before the discharge phase begins being equal to or greater than the pressure existing in the zone occupied by the said fluid. In the device a motor is provided for reciprocating the syringe pistons and a commutation device is provided for communicating each syringe orifice in turn and alternately to the fluid and to a source of adjuvant.
