Patent ID: 10362925

Abstract:
A dosing device includes an electrically controlled valve device driven at each operating cycle of the machine with a first short pulse for the actuation of another function and then with a subsequent second long pulse to put the dosing chamber in communication with the main chamber and then causing the dispensing of a dose of washing agent from the dosing chamber to the washing chamber. The valve device controls the communication between the intermediate chamber and the dosing chamber whereby the first impulse is able to put the intermediate chamber in communication with the dosing chamber for a short time, causing a partial discharge of the air bubble from the intermediate chamber to the dosing chamber and a corresponding increase in the amount of washing agent contained in the intermediate chamber, and the second impulse is adapted to put the intermediate chamber in communication with the dosing chamber for a longer time, adapted to allow the storage of a dose of washing agent in the dosing chamber and, after exhausting the second impulse, the dispensing of the dose of washing agent stored in the dosing chamber.
