SPRAY NOZZLE

摘要

PURPOSE:To prevent a spray angle from narrowing by making a supporting part of a paint nozzle into a flat projection along an injection port and forming the lip-shaped injection port into a notch corresponding to said projection. CONSTITUTION:A lip-shaped notched groove 21 is formed by cutting a tip of a paint nozzle 2 so that the notched groove is inserted under pressure and fitted toward the lengthwise direction of the top face and a lip-shaped orifice type injection port 34 is formed by a notched groove 32 and a recess part 33 on a trapezoid-shaped top face 31 of an air nozzle 3 and a notch 35 is formed by cutting the center of both the mouth edges of said port 34 and the paint nozzle 2 is sandwiched to make an air flow path (a). By this way, acceleration of spraying and prevention of scattering of spray droplets are performed effectively and wide angle spray free from turbulent flow is made possible.
