Jetting dispenser with multiple jetting nozzle outlets

摘要

A jetting dispenser has a dispenser body with a fluid channel (14) and a fluid channel outlet (18) within the fluid channel. A valve member (22) is movable within the fluid channel (14) for selective contact with a valve seat (20) near the fluid channel outlet (18). A jetting nozzle is adapted to be coupled to the dispenser body, adjacent the channel outlet, and has a nozzle body (82) with a plurality of nozzle outlets in fluid communication with the channel outlet via a plurality of fluid passages through the nozzle body. The valve member is moved by a valve driver to contact the valve seat and impart momentum to liquid material supplied to the dispenser such that a plurality of droplets of liquid material are simultaneously jetted from the plurality of nozzle outlets.
