The system for transfer of liquids (P), in particular viscous liquids, comprises a cylindrically shaped intermediate chamber (15, 17) one of the walls of which is defined by a piston (1), said chamber (7) comprising an inlet opening (14) having a check valve (16) and an outlet opening (18). The piston (1) has a variable diameter, which is at its minimum in a suction phase and at its maximum in a discharge phase. |
