Abstract

A jetting device and/or fluid module includes a nozzle with a fluid outlet, a body including a fluid chamber and a fluid inlet in fluid communication with the fluid chamber, and a valve seat disposed in the fluid chamber, where the valve seat includes an opening in fluid communication with the fluid outlet. The jetting device also includes a movable element having a top portion and a bottom portion, where the top portion is disposed external to the fluid chamber and arranged to be contacted by a reciprocating drive pin, and where the bottom portion is disposed within the fluid chamber. Finally, the jetting device also includes a sealing member contacting the movable element between the top portion and the bottom portion, where the sealing member also contacts the body, and defines a portion of a boundary of the fluid chamber to seal the fluid chamber.
