The invention relates to a synchronously operating liquid dosing appliance with internal pressure regulation independently of the dosage, characterised by a closed container for housing at least one liquid to be dosed, at least one liquid to be dosed, an internal pressure control system, a distribution control system, and a support, the internal pressure system enabling a pre-determined quantity of air to enter each time the admissible pressure differential between the pressure inside the container and the pressure outside the container drops. |
