Abstract:
1. A fluid dispenser head comprising: an inlet well for connecting to an outlet of a dispenser member; an axial assembly housing in which there extends a pin defining a side wall and a front wall; and a cup-shaped nozzle comprising a substantially-cylindrical wall having an end that is closed by a dispenser wall that forms a spray orifice, the nozzle being assembled along an axis X in the axial assembly housing, with the substantially-cylindrical wall engaged around the pin, and the dispenser wall in axial abutment against the front wall of the pin; the head further comprising: at least two feed ducts, each connecting the inlet well to the axial assembly housing; the front wall of the pin forming at least two swirl channels that are connected in tangential manner to a swirl chamber that is centered on the spray orifice; and the cylindrical wall of the nozzle being in sealing contact with the side wall of the pin so as to define at least two connection sections, each connecting a feed duct to a swirl channel, the cylindrical wall of the nozzle being in sealing contact with the side wall of the pin at at least two sealing zones that extend in substantially axial manner from the ducts to the channels so as to form the at least two connection sections, wherein the sealing zones are linear and axial, Wherein the sealing zones are formed by axial splines on the pin that are in contact with the cylindrical wall of the nozzle, the axial spline protrusions extending along the direction of the axis X.
