Abstract:
A spray apparatus, comprising:a nozzle for spraying a material therethrough in a spray direction; a nozzle cap having an exit aperture, said nozzle cap disposed around said nozzle for only linear movement between (1) a retracted position in which said nozzle cap abuts against said nozzle, and (2) an extended position in which said nozzle cap is spaced apart from said nozzle to define a gap therebetween; and an air inlet for receiving air from an external source, wherein said gap accommodates a discharge of the air around said nozzle to achieve a desired spraying area, wherein, when said nozzle cap is in said extended position, said exit aperture of said nozzle cap is positioned downstream from said nozzle relative to said spray direction, such that a spray of said material first exits said nozzle and then passes through said exit aperture of said nozzle cap.
