Abstract
A spray gun includes a main piston chamber having an actuatable piston and a gun block. The gun block includes a mixing chamber that has a pair of impingement holes that each tangentially intersects with an exit hole of the mixing chamber at opposing tangential points. The gun block also includes a tip that is coupled to an end of the mixing chamber and has a pattern channel that is substantially axially aligned with the exit hole of the mixing chamber. The length of the pattern channel is less than the length of the exit hole of the mixing chamber. In some versions, the ratio of the pattern channel to the combined length of the pattern channel and exit hole can be between 31%, inclusive, and 5%, inclusive. A selectively coupleable handle may be provided such that users can utilize different handles with the spray gun.
