Abstract
Electrically-operated dispensing modules capable of dispensing small volumes of a viscous liquid at high operating frequencies and reproducibly among successive dispensed volumes of viscous liquid without the occurrence of stringing. The dispensing module may include a flux element having a portion effective for interrupting circumferential electrical current paths. In another aspect, an end face of a pole piece of the dispensing module may include one or more non-magnetic spacer elements that prevent contact between the pole piece and armature when the dispensing module is opened.
