Abstract
Apparatus and methods for dispensing small amounts of a viscous material onto a workpiece. The narrow-profile dispensing apparatus includes a fluid chamber, a nozzle, and a valve seat disk representing individual components that are removable from a main body of the dispensing apparatus for cleaning and/or replacement. The nozzle is coupled with the fluid chamber by a heat transfer body that may be cooled by, for example, a cooling fluid routed through an air pathway defined in the heat transfer body. The main body of the dispensing apparatus may be cooled by air exhausted from an air cavity of a pneumatic actuator regulating the movement of a needle to control the flow of viscous material in the dispensing apparatus.
