an inner groove (12) connecting the first conduit (5) to the product to be metered;

at least one pumping element (7,7a) for feeding and metering the product, fluidly connected to the inner recess (12) and to the second duct (9) for discharging the metered product;

-motor means (6,6a) connected to the shaft (11, 11a) by means of a linear actuator (4, 4a), said linear actuator (4, 4a) being adapted to convert the rotary motion of the motor means (6,6a) into a linear motion of the shaft (11, 11a) which is carried out until the shaft (11, 11a) comes into abutment with the second outlet duct (9); after the shaft (11, 11a) reaches abutment, the movement of the shaft (11, 11a) is adjusted to follow the rotary movement of the motor means (6,6a) to drive the pumping element (7) and deliver the product from the second outlet duct (9);

characterized in that the device further comprises:

a second pumping element (7a) fluidly connected to the inner recess (12) and to a second conduit (9) for metering the product;

a second shaft (11a) connected to the second pumping element (7 a);

-second motor means (6a) connected to the shaft (11, 11a) by means of a second linear actuator (4a), said linear actuator (4, 4a) being intended to convert the rotary motion of the motor means (6,6a) into a linear motion of the shaft (11, 11a), the linear motion being carried out until the shaft (11, 11a) reaches abutment with the second outlet duct (9); after the shaft (11, 11a) reaches abutment, the movement of the shaft (11, 11a) is adjusted to follow the rotary movement of the motor means (6,6a) to drive the pumping element (7) and deliver the product from the second outlet duct (9);

wherein the flow rate of the second pumping element (7a) is greater than the flow rate of the pumping element (7) to regulate the flow rate by driving two or one of the two pumping elements (7,7 a); the linear actuator (4, 4a) is composed of a worm with a bidirectional pitch, the spiral of which is connected with the motor device (6,6a) through a shaft (11, 11 a); the pump element (7,7a) is a positive displacement pump comprising a pump chamber (14, 14a) in which a rotor (15, 15a) is mounted, the rotor (15, 15a) being connected to the shaft (11, 11a) and to the gate (16, 16 a); a shutter (16, 16a) for closing the outlet nozzle (8, 8a) of the product, the outlet nozzle (8, 8a) communicating the inner recess (12) with the second duct (9); the second pumping element (7a) has a pump chamber (14a) with a volume greater than the pump chamber (14) of the pumping element (7) in order to regulate the flow rate by opening only one of the two outlet nozzles (8, 8a) or both outlet nozzles (8, 8a) simultaneously, in order to meter more accurately the product delivered by the second outlet conduit (9).

2. Device (10) for conveying and metering a powdered, liquid, pasty or creamy product according to claim 1, characterized in that said pumping element (7,7a) is a volute pump or a positive-displacement pump, said motor means (6,6a) being constituted by a stepper motor.
