Claim Text:
1. A fluid module for use with a jetting device, the jetting device having a drive pin external to the fluid module that is reciprocated by an actuator, the fluid module comprising: a nozzle with a fluid outlet; a module body including a first portion with a fluid inlet, a second portion configured to support the nozzle, and a fluid chamber; a valve seat with an opening communicating with the fluid outlet; a movable element having a wall arranged to be contacted by the drive pin and configured to move when the drive pin is reciprocated; a sealing member in contact with an exterior of the movable element and configured to provide a fluid seal with the movable element such that a part of the movable element defines a portion of a boundary of the fluid chamber; a valve element enclosed within the fluid chamber between the wall of the movable element and the valve seat, the valve element attached to the movable element, and the valve element and the movable element configured to be moved in a direction toward the valve seat in response to the wall of the movable element being contacted by the drive pin, wherein 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 valve seat; and a biasing element contacting a periphery of the movable element, the biasing element also contacting the module body, the biasing element being configured to apply an axial spring force to the movable element such that the valve element and the movable element move away from the valve seat under the action of the axial spring force after the drive pin is reciprocated out of contact with the wall of the movable element.
