ABSTRACT:
The system comprises a first alternating pump (1) for injecting a dose of a first component (4) into a mixer (3) and a second alternating pump (2) for injecting a dose of a second component (5) into the mixer (3) sequentially relative to the first pump. The movement of the piston of each pump can be reversed from a direction of suction and expulsion of the pump to a direction of expulsion of the corresponding component, and vice versa. An injection valve (10, 11) is inserted between each pump (1, 2) and the mixer (3). The system also comprises a programmed controller (20) for initiating the movement of the piston of a pump in the direction of suction and expulsion of the volume of this pump after having determined, following the closing of the injection valve (10, 11), that the remaining volume in the pump (1, 2) is inadequate for injecting the following dose into the mixer (3).
