Abstract
This invention concerns a method and apparatus for dispensing minute quantities of fluids and more particularly rapidly dispensing highly precise and repeatable, minute amounts of viscous fluids in a non-contact manner. An impacting element is impacted against a hardened insert on a flexible diaphragm to deflect the insert into a jetting chamber and against an outlet orifice in the jetting chamber. The movement of the diaphragm and insert force viscous fluid in the chamber through the outlet orifice and the impact jets that fluid from the outlet orifice, with the impact force being adjusted to jet the fluid from the orifice in a single drop.
