  • Patent number: 4253610
    Abstract: A modified abrasive blast nozzle is disclosed in the preferred embodiment which incorporates an elongate fitting having threads enabling it to be connected with a hose, an internal axial passage which tapers into a narrow neck and thereafter flares outwardly, the axial passage flaring at an internally located, encircling, water inlet manifold, the manifold being communicated to the axial passage by a number of small openings, and the nozzle body further including an inlet pipe connection for water. Abrasives under high pressure with a high volume of air flows through the axial passage. As it moves past the openings into the manifold, an aspirator effect is achieved which pulls water or other liquids from the aspirator manifold into the outlet flow of air and blasting or abrasive media to thereby moisten the media and surface as needed to prevent formation of a cloud of dust and to neutralize and/or trap any airborne chemical, free silica or contaminants.
