Abstract
A dispensing head for air assisted and airless application of a material to a surface includes a cylindrical barrel having a supply passage therein for the material to flow from a source to a nozzle. The barrel includes at one end a nozzle seat that slideably receives a nozzle body. The nozzle body has a bore that opens at one end to the barrel passageway, and at another end has a nozzle tip with an orifice through which material is dispensed. The nozzle body has a groove formed therein that receives a seal. When the nozzle body is inserted into the nozzle seat, the seal is compressed between the nozzle groove wall and a wall of the nozzle seat to hold the nozzle within the nozzle seat during further assembly of the dispensing head. The seal is preferably captured and isolated from a set of air jets that are formed in the nozzle body, thereby preventing the seal for blocking the air jets.
