Abstract
A dispensing module and method of dispensing an adhesive includes a dispenser body having a valve element and a nozzle. The nozzle includes a nozzle member, a sealing zone, and a valve seat. The nozzle member includes a liquid passageway having a bore, a cylindrical surface, a second converging surface, and a shoulder. The sealing zone is defined by the cylindrical surface and extends from the bore toward the shoulder and engages the valve element to close a first volume of the liquid passageway from the inlet. The valve seat is defined by the shoulder and the second converging surface and has a circular line of contact that engages the valve element to close a second volume of the liquid passageway from the inlet. The first volume reduces to the second volume as the valve element moves distally along the sealing zone for discharging the adhesive.
