A twin-piston food pump (10) includes a hydraulic cylinder (38a, 38b) coupled with each piston (34a, 34b) for driving the pistons (34a, 34b) and a linear transducer (18a, 18b) coupled with each cylinder (38a, 38b) for determining the positions thereof. Control circuitry (20) coupled with the transducers (18a, 18b) determines the velocity of the cylinders and thereby the pistons (34a, 34b) and controls the application of hydraulic fluid through the cylinders (38a, 38b) to maintain a constant food product flow rate.
Une pompe (10) à aliments à pistons jumeaux comprend deux cylindres hydrauliques (38a, 38b) couplés chacun avec un piston (34a, 34b) pour actionner les pistons (34a, 34b) et un transducteur linéaire (18a, 18b) couplé avec chaque cylindre (38a, 38b) pour déterminer leurs positions. Un circuit de commande (20) couplé avec les transducteurs (18a, 18b) détermine la vitesse des cylindres et donc des pistons (34a, 34b) et commande l'alimentation en fluide hydraulique des cylindres (38a, 38b) pour maintenir un débit constant de produits alimentaires.
