ABSTRACT:
A nozzle, and gun for using the nozzle for projecting material outwardly therefrom. The gun has means for receiving a supply of material and a valve for controlling passage of material through the gun. The nozzle has a housing, and a passage in the housing. The passage has first and second ends and a longitudinal axis. The passage extends, from its first end, into the interior of the housing and opens into a chamber in the housing at the second end of the passage. The first end of the passage has a first surface flared outwardly at an average angle no greater than 75 degrees from the longitudinal axis. A shaft extends from the chamber through the passage and terminates, at a tip, at a location adjacent the first end of the passage. The shaft is positioned in the passage to provide a symmetric orifice between the passage and the shaft. The tip has a second surface flared outwardly at least 15 degrees from the longitudinal axis. The first and second surfaces cooperate, in projection of drywall coating material through the nozzle at pressures of 1,000 psi to 1,500 psi, to break up the drywall material into discreet particles and thereby create a substantially uniform pattern. The nozzle further includes means for introducing the material, to be projected, into the chamber.
