The invention relates to a periodically operating liquid dosing device with a high level of reliability, characterised by a container for housing at least one liquid to be dosed, at least one liquid to be dosed, a dosage control system for each liquid, a distribution device and a support, the dosage control system for each liquid separating the quantity to be dosed by applying a fluid in a gaseous state having a higher pressure than the lower pressure in the space of the recess where the dosage is to be distributed, creating a pressure differential in the ends of the quantity to be dosed with the force necessary to overcome the superficial tension of the liquid to be dosed and thereby separate the quantity to be dosed and carry out the dosage reliably, while said fluid applied in a gaseous state ascends the inside of the container in order to compensate for the pressure caused by the loss of volume of the dosed liquid. |
