<p>This device for rapid and extremely accurate filing of bottles includes a volumetric bi-acting piston, a submersible filling nozzle which opens only when it is actually dispensing and which carries an antidrip suction mechanism adapted to draw off only air above the fluid level when it is not picking up drips from the nozzle tip, provisions for control to avoid dispensing operations when no bottle is present in receiving position, and adjustability of volume and flow rate individually and volume in common for all filling heads in a multiple-head system -- all without stopping the filler. Also included are provisions for preventing entrainment of air in the system, and for removing any air which is originally trapped in the system at startup or through operation of a supply pump.</p> |
