A nozzle for a spray gun comprises a fixed assembly and a displaceable assembly; the fixed assembly comprising a tubular nozzle housing (1) having an inlet end (2) connectable to a fluid supply, and having an outlet end (3) and a flow passage extending from the inlet end (2) to the outlet end (3), the displaceable assembly comprising a pressure regulating mechanism arranged in said flow passage at the outlet end (3) in order to control the nozzle pressure Said mechanism comprises a stem (6); a baffle (7) mounted for axial displacement on said stem (6) in said flow passage defining a nozzle gap (20) between said baffle (7) and the housing (1). The fixed assembly further comprises means (12) to distribute a passing fluid flow and to support a second end (6b) of the stem and the means are fixed inside the housing (1 ), said means (12) further being adapted to fixedly receive a valve cone (5) connectable to an axially displaceable fluid supply tube (8) for supplying a fluid. First biasing means (10) adjust the maximum baffle displacement at a first flow rate interval and second biasing means (14) supplement said first biasing means (10) at a second flow rate interval, counteracting additional fluid pressure on the baffle (7).
