Abstract
A dispensing head with a staged swirling chamber for a dispensing system includes a spraying nozzle including a dispensing orifice and a swirling chamber opening into the dispensing orifice, the swirling chamber including a converging portion, and extending along an axis between an upstream end and a downstream end in the direction of displacement of the product, and an anvil including a core provided with a peripheral wall, that is housed inside the swirling chamber, and forming with the converging portion at least one fluidic path in which the product circulates, the converging portion including an inner wall of the nozzle, the inner wall and/or the peripheral wall of the core being provided with a plurality of steps, each step being defined by a transverse wall that extends in a plane secant to the axis and a longitudinal wall substantially parallel to the axis, the steps forming obstacles in the fluidic path.
