Integrated dispensing device for a rotatable door of a washing machine, in particular a dishwasher machine, comprising - a support body wherein there are provided first and second dispensers (5-10; 13-18), adjacent one another, for a washing agent and a rinsing agent, respectively; and - an electrically-controlled actuator device, coupled to the first dispenser such that when the door is closed a first energisation of the actuator device causes the dispensing of the washing agent, and coupled to the second dispenser through a transmission mechanism (40; 61-65) predisposed to become enabled to operate after a first energisation of the actuator device after the door is closed, to allow the dispensing of the rinsing agent as a consequence of at least one subsequent energisation of the actuator device; characterized in that the second dispenser comprises - a main chamber adapted to contain a plurality of doses of rinsing agent, - a dosing chamber having a predetermined volume, corresponding to that of a dose, and having an inlet opening and an outlet opening to be coupled with the main chamber and with a discharge conduit, respectively, and a valve device including an obturator mounted movable in the dosing chamber and controlled by said actuator device such that * when the actuator device is energised, after the transmission mechanism (40; 61-65) has been enabled for operation, the obturator passes from a rest position in which it uncouples the dosing chamber from the main chamber, to a loading position, opening the inlet and keeping constantly closed the outlet of the dosing chamber, to allow a flow of rinsing agent from the main chamber to the dosing chamber through said inlet; and * when the actuator device is subsequently de-energised, the obturator returns from the loading position to the rest position, opening the outlet opening and still closing the inlet opening of the dosing chamber; the arrangement being such that during the displacement of said obturator between the rest position and the loading position, the main chamber remains permanently uncoupled from the discharge conduit. - a support body wherein there are provided first and second dispensers (5-10; 13-18), adjacent one another, for a washing agent and a rinsing agent, respectively; and - an electrically-controlled actuator device, coupled to the first dispenser such that when the door is closed a first energisation of the actuator device causes the dispensing of the washing agent, and coupled to the second dispenser through a transmission mechanism (40; 61-65) predisposed to become enabled to operate after a first energisation of the actuator device after the door is closed, to allow the dispensing of the rinsing agent as a consequence of at least one subsequent energisation of the actuator device; characterized in that the second dispenser comprises - a main chamber adapted to contain a plurality of doses of rinsing agent, - a dosing chamber having a predetermined volume, corresponding to that of a dose, and having an inlet opening and an outlet opening to be coupled with the main chamber and with a discharge conduit, respectively, and a valve device including an obturator mounted movable in the dosing chamber and controlled by said actuator device such that * when the actuator device is energised, after the transmission mechanism (40; 61-65) has been enabled for operation, the obturator passes from a rest position in which it uncouples the dosing chamber from the main chamber, to a loading position, opening the inlet and keeping constantly closed the outlet of the dosing chamber, to allow a flow of rinsing agent from the main chamber to the dosing chamber through said inlet; and * when the actuator device is subsequently de-energised, the obturator returns from the loading position to the rest position, opening the outlet opening and still closing the inlet opening of the dosing chamber; the arrangement being such that during the displacement of said obturator between the rest position and the loading position, the main chamber remains permanently uncoupled from the discharge conduit.
