Abstract

A jetting device and/or fluid module include a module body defining a passageway extending through the module body and also partially defining a fluid chamber, a nozzle supported by the module body, a valve element at least partially within the fluid chamber, a biasing element contacting the valve element and also contacting the module body, and a sealing member contacting the periphery of the valve element and configured to partially define the fluid chamber. The nozzle defines a fluid outlet that is in fluid communication with the fluid chamber. The valve element has an upper portion outside of the fluid chamber that is adapted for contact with the drive pin, and the biasing element is configured to apply a spring force to the valve element. The valve element is configured to cause a droplet of the fluid to be jetted from the fluid outlet when the valve element is moved in the direction toward the nozzle.
