The apparatus according to the invention comprises a hopper 3 storing a divided product 4, two nozzles 7a, 7b which connect the base 5 of the hopper to a reception chamber 8 provided with an outlet orifice 9, two metering pistons 13a, 13b aligned with the two nozzles and connected to a connecting rod 16 which pivots about a vertical spindle 17 and which is actuated by a double-acting pneumatic cylinder 20. The chamber 8 is connected on to a pipeline 12 which sends into the chamber pulses of compressed gas synchronised with the movements of the cylinder. One application is the dispensing doses of a few grams each on to products which are moving along a conveyor belt of an automatic machine. <IMAGE>
