Abstract
A spraying apparatus for spraying a particle-laden fluid upon a workpiece. The apparatus includes a spray compartment, spray gun means in the compartment, exhaust means for exhausting air-entrained particles, and means for flowing air past the spray gun means to prevent air-entrained particles from returning to the spary gun means. The exhaust means may include means for abruptly changing the direction of air entraining the sprayed particles from a direction generally toward the workpiece to be sprayed to a direction generally away from the workpiece, whereby the air-entrained particles are urged into contact with the workpiece.
