    摘要: A plural component spray gun which can be used as an air atomizing gun for atomizing material at the nozzle for external mixing with a catalyst, and, which is convertible to airless operation. The spray gun has a nozzle body which incorporates passageways for delivering atomizing air and a fluid component to a mixing chamber at the outlet to one of a plurality of nozzles attached to the nozzle body. To convert the spray gun to airless operation, the nozzles are removed, and a sleeve inserted in the air atomizing chamber. One of the nozzles is replaced with an airless type and they are reattached to the gun body. The replaced nozzle has a centrally located annular flange which extends into the air atomizing chamber to hold the sleeve insert in the chamber to seal the air passageway. The centrally located annular flange on the replaced nozzle also includes an annular cavity, into which an insert having an orifice restriction can be inserted for increasing the velocity of the component during airless operation. The spray gun is easily converted back to air atomizing operation by removal of the airless nozzle and sleeve sealing the air passageway and replacement with the air atomizing nozzle.
