A proportioning system (20) includes first and second cylinder and piston arrangements (26, 28) with an actuator (30) operably engaging the first and second cylinder and piston arrangements (26, 28). By changing the diameter and/or stroke of the pistons (54, 56), the mix ratio of two dispensed fluids changes. By changing the pivot point (32) of the actuator (30), the stroke length can be changed. The proportioning system (20) also includes a safety mechanism which prevents a concentrated fluid from being dispensed should the reservoir of diluting fluid be depleted.
L'invention porte sur un système de dosage (20) comprenant un premier et un deuxième ensembles cylindre/piston (26, 28) et un vérin (30) agissant sur lesdits ensembles. En modifiant le diamètre et/ou la course des pistons (54, 56), on fait varier le rapport de mélange entre les deux fluides distribués, la modification de la course s'obtenant en déplaçant le point de pivotement (32) du vérin (30). Le susdit système (20) comporte un mécanisme de sûreté empêchant la distribution d'un fluide concentré au cas où le réservoir de diluant soit vide.
