(54) Washing machine with improved device for the liquid supply and dosage, and dosage method thereof


(57) A washing machine is described, comprising a metering device (1) for the liquid required to perform at least a washing phase, said device comprising at least a first metering chamber (VI) and a second metering chamber (V2). Each chamber (V1,V2) has a relevant discharge solenoid valve (EV1,EV2) and the liquid metering is performed by supplying the liquid to said chambers (V1,V2) and the subsequent discharge of the liquid contained in at least one of said chambers (V1,V2) into the washing tub (FV) of the machine; said supply and discharge are repeated in the frame of one same liquid metering phase and said chambers (V1,V2) can be discharged independently from each other. In a possible embodiment of the invention, the control of the operation of the metering device (1) is obtained through a programmer of the electromechanical cam type.
