ABSTRACT:
A pushbutton for actuating a device for dispensing or spraying a fluid substance includes a hollow body 1 having an outlet end 2 in which an outlet orifice 3 is formed, the outlet end including an inside surface 2a which is not perpendicular to the axis 1a of the body. An adjustment member 10 is rotatably received in the body of the pushbutton, and includes a shutter 19 provided with a front surface 19a that is complementary in shape to the inside surface of the outlet end. The shutter is urged towards the outlet end by a resilient tongue 18. The rotation of the adjustment member and shutter varies the outlet flow rate from the pushbutton.
