Compensating Pressure Controller For Fluid Dispenser And Method

US Patent:
8136707, Mar 20, 2012
Filed:
Apr 3, 2006
Appl. No.:
11/278465
Inventors:
Michael A. Vidal - North Attleboro MA, US
Assignee:
Nordson Corporation - Westlake OH
International Classification:
B67D 7/08
US Classification:
222639, 222 55, 222 61, 222389
Abstract:
A fluid dispensing system having a fluid dispenser supporting a barrel containing liquid to be dispensed. The barrel has a slidable piston therein with the liquid on a forward piston side and a chamber on a rear piston side. Positive and negative pressure fluid circuits have components operable to apply respective positive and negative fluid pressures to the rear side of the piston. A pressure transducer is operable to sense a fluid pressure in the chamber; and a dispenser control is operative to store a pressure-time relationship during a first dispensing cycle and thereafter, operate a component in the positive pressure fluid circuit to maintain the pressure-time relationship during a subsequent dispensing cycle.

Compensating Pressure Controller For Fluid Dispenser And Method

US Patent:
8365952, Feb 5, 2013
Filed:
Mar 13, 2012
Appl. No.:
13/418601
Inventors:
Michael A. Vidal - North Attleboro MA, US
Assignee:
Nordson Corporation - Westlake OH
International Classification:
G01F 11/04
US Classification:
222 1, 222 55, 222639
Abstract:
A fluid dispensing system having a fluid dispenser supporting a barrel containing liquid to be dispensed. The barrel has a slidable piston therein with the liquid on a forward piston side and a chamber on a rear piston side. Positive and negative pressure fluid circuits have components operable to apply respective positive and negative fluid pressures to the rear side of the piston. A pressure transducer is operable to sense a fluid pressure in the chamber; and a dispenser control is operative to store a pressure-time relationship during an initial dispensing cycle and thereafter, operate a component in the positive pressure fluid circuit to maintain the pressure-time relationship during a subsequent dispensing cycle.
