Abstract: A fluid spray head comprising an expulsion channel (5) provided with a spray orifice (1) and a spray profile (10) formed in an end wall of said spray head, said spray profile (10) comprising preferably non-radial spray channels (11) opening out to a central spray chamber (12) disposed directly upstream from said spray orifice (1), an insert (20) being disposed in said expulsion channel (5) so as to form a cover for said spray profile (10), the central axis (X) of said insert (20) being substantially identical to the central axis (Y) of said expulsion channel (5), and said spray head including centering means for centering said insert (20).

Abstract: A spray-inspection machine for an assembly line for assembling a fluid spray device, the machine comprising: a support receiving at least one fluid spray device taken directly from the assembly line; an actuator system for actuating a fluid spray device of said support and for creating a fluid spray; determination means for determining real parameters of said spray created by said actuator system; and analyzer means for analyzing said real parameters, said analyzer means comparing said real parameters with pre-determined parameters, wherein said analyzer means determine parameters relating to spray shape and/or particle size and/or particle density and/or particle-size distribution and/or particle speed.

Abstract: A fluid product spray head (40) comprises a spray orifice (45) and a spray profile (100) upstream from this spray orifice (45). Said spray profile has a swirling chamber (101) connected, during the spraying of the product, to the spray orifice (45) and to at least one non-radial channel (110) connected to the swirling chamber (101). The spray profile (100) is provided in the bottom of the spray head (40). A obturator (38) interacts with the spray orifice (45) while being able to be displaced and/or deformed between a closing position of the spray orifice (45) and an open position of the spray orifice (45). The inventive spray head (40) has an axially hollow sleeve (150) that accommodates the spray profile (100), and said obturator (38) axially displaces and/or deforms at least partially in said sleeve (150).
