Abstract
An applicator for spraying an elastomeric material comprises an applicator body having an internal bore and a fluid inlet for receiving a supply of the elastomeric material. A nozzle is coupled to the applicator body and has a discharge end with a spray outlet in fluid communication with the fluid inlet via a fluid passageway. A needle valve is slidably mounted within the internal bore for movement between a closed position for closing the fluid passageway, and an open position for opening the fluid passageway so as to spray the elastomeric material. An air cap is coupled to the applicator body adjacent the nozzle for providing an atomizing airflow and a fan control airflow. The needle valve has a tip portion shaped to extend through the nozzle so as to be substantially flush with the discharge end of the nozzle when the needle valve is in the closed position.
