The invention relates to a device for portioning flowable food products, consisting of: a first group of cylinders ( 1 ) comprising pistons ( 3 ) which communicate with a chamber ( 5 ) having an inlet ( 5 a) and an outlet ( 5 b); a second group of cylinders ( 2 ) comprising pistons ( 4 ) which communicate with a chamber ( 6 ) having an inlet ( 6 a) and an outlet ( 6 b), and dispensing means. Said dispensing means are controlled by synchronisation and control means in order to: alternately communicate a food product inlet ( 9 ) with said chamber ( 5 ) whereby the cylinders ( 1 ) open the inlet ( 5 a) and close the outlet ( 5 b) thereof; and simultaneously communicate an outlet ( 10 ) with said chamber ( 8 ) whereby the cylinders ( 2 ) close the inlet ( 56 a) and open the outlet ( 6 b) thereof and vice versa. Fluid dynamic cylinders ( 26 ) actuate each piston ( 3, 4 ) consecutively or actuate on sub-groups of pistons ( 3, 4 ) consecutively in order to empty the cylinders ( 1, 2 ).
