ABSTRACT:
A spray gun having a liquid delivery pipe provided with a nozzle openable by an axially movable control member which plugs an axial hole, has an adjustable diffusing member arranged downstream of the nozzle. The diffusing member has a pair of flexible parallel tangs integrally extending forward from the nozzle and a hollow sleeve arranged rotatably to incline the tangs at a selected angle, i.e., at a greater or lesser distance from one another than the diameter of the axial hole. The tangs each have a protruding tooth engaging in a spiral arc in the tightening sleeve collar, whereby rotation of the tightening sleeve collar moves the tangs toward or away from one another, up to extremities of the spiral arcs.
