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.

A nozzle comprising a housing having a first end, and a passage in said housing, said passage having first and second ends and a longitudinal axis, said passage extending, from said first end of said housing at said first end of said passage, into the interior of said housing, and opening into a cha
A nozzle comprising a housing having a first end, and a passage in said housing, said passage having first and second ends and a longitudinal axis, said passage extending, from said first end of said housing at said first end of said passage, into the interior of said housing, and opening into a chamber in said housing at said second end of said passage, said first end of said passage having a first surface flared outwardly, a male member in said housing, having an end disposed toward said first end of said passage, a shaft comprising an elongated constant cross-sectioned portion extending from said end of said male member and from said chamber, through said passage, and an enlarged tip extending from said constant cross-sectioned portion, at a location adjacent said first end of said passage, said enlarged tip having a second surface flared outwardly from said constant cross-sectioned portion of said shaft, means for introducing a material into said chamber for dispensing said material through said passage, adjusting means for adjusting the position of said shaft longitudinally in said passage within an operating range, for modifying the pattern of dispensing of said material, including a full open position at a first end of said range wherein said end of said male member is disposed closest to said first end of said passage, thereby opening said nozzle for maximum flow of said material, and a constant cross-sectioned space between said constant cross-sectioned portion of said shaft and interior walls of a constant cross-sectioned portion of said passage, said constant cross-sectioned space extending outwardly from said second end of said passage, to the first-to-be encountered of said first and second flared surfaces, when said shaft is adjusted in said full open position, with said male member being disposed closest to said first end of said passage.
