Abstract
A lance extension venturi sleeve is disposed preferably within the rear one-third of the lance extension of a powder spray gun. The sleeve increases the velocity of the powder stream and provides an abrupt opening to the larger lance extension tube. The velocity increase and the turbulence so created increase the homogeneity of the powder in the stream and produce a more uniform powder spray pattern or powder 'cloud' for even powder coating of articles to be coated.
