Definitions

  • the present invention relates to a dispensing nozzle, for dispensing a fluid contained in a container as known for example from document FR-A-1 158 992.
  • the distribution nozzles provided of an outlet for the fluid to be distributed, are crossed by this fluid following a user action: this action is, for example, pressure exerted on the walls of the container then provided flexible, or actuation of a support, equipped with the nozzle, which controls the opening of a valve with which the container is equipped then filled with pressurized gas to propel the fluid to be distributed to the through the nozzle, or which implements means for pumping the fluid.
  • this action is, for example, pressure exerted on the walls of the container then provided flexible, or actuation of a support, equipped with the nozzle, which controls the opening of a valve with which the container is equipped then filled with pressurized gas to propel the fluid to be distributed to the through the nozzle, or which implements means for pumping the fluid.
  • the dispensing nozzle has a distribution which extends around the axis of the nozzle and is supplied, from the tank, by a supply duct whose axis forms a angle with the axis of the nozzle, this angle most often being straight.
  • the object of the present invention is to minimize the losses of loads of the path traveled by the fluid, from the reservoir to the nozzle outlet.
  • the present invention relates to a dispensing nozzle comprising at least one outlet orifice arranged along the axis of said nozzle, a distribution channel extending around the axis and being supplied with fluid to be distributed by an axis supply duct, the axis of the nozzle and the axis of the conduit making an angle between them, supplying the distribution channel via the conduit tangentially to said channel, the distribution channel being formed between, on the one hand, the periphery of a centered centering core by a support equipped with said distribution nozzle and, on the other hand, a bore centered on the axis, and carried by said support, said bore communicating, at one of its ends, with the conduit and, at its other end, with the outlet orifice, said bore having a shape complementary to that of the centering core and being located at a distance of it and the centering core being molded with transverse play in the bore, the channel being constituted by the space defined by said clearance transverse, characterized in that a partition connects the core centering on
  • the centering core is mounted with transverse play in the bore, the distribution channel being constituted by the space defined by said transverse play.
  • the centering core can be cylindrical, on at least part of its length, and / or conical, converge towards the orifice of exit ; it can also be in the form of a warhead whose cross section transverse decreases regularly towards the exit orifice.
  • the supply duct is connected tangentially to the distribution channel by a portion of progressive connection of the sections, respectively, of the duct supply and distribution channel; alternatively, the sections of the duct and channel are equal.
  • the axes of the dispensing nozzle and the supply ducts are orthogonal.
  • the nozzle of distribution includes two outlet ports and two distribution supplied by a single supply duct; advantageously, the sum of the sections of the two channels of distribution is equal to the section of the supply duct.
  • a dispensing nozzle consists of a centering core 3 of shape general cylindrical, mounted without transverse play inside a bore 10 carried by a support 1, for example a push button equipped with said nozzle; bore 10 is the internal bore of a sleeve 2 secured to the push button 1 in an open bore 13 thereof outside ; the centering core 3, the sleeve 2 and the bore 13, all three of revolution, have a common axis 20.
  • the sleeve 2 has, at its end close to the outside, a bottom, the face of which interior 11 is conical, pierced with an outlet orifice 6 along axis 20, said orifice 6 consisting of a cylindrical nozzle opening to the outside in a part of divergent conical shape; opposite the conical interior face 11 of the bottom of the sleeve 2, the end of the centering core 3 has a part frustoconical, designated by the reference 12 in the figure, connected to a flat face perpendicular to the axis 20 and located at a distance from the orifice 6.
  • a distribution channel 4 extending helically: was designated 4 has the first coil, of the propeller which constitutes the channel 4, with reference to the direction of flow of the fluid, as will be seen below, and with 4 n the last turn; the coil 4 n ends at the right of the frustoconical part 12 of the end of the core 3; 4 has the first turn originates at the opposite end of the core 3 (relative to the end of said core 3 which faces the orifice 6) extending outside the bore 10 of the sleeve 2 , so that an annular chamber 8, of axis 20, is defined by the core 3, the sleeve 2 and the support 1; the coil 4 a communicates with the interior of the chamber 8.
  • the support 1 carries, as is known, a rod control 5, of axis 15, intended for actuating means of conventional distribution systems, such as a distribution valve, or a distribution pump, allowing the fluid to be conveyed to distribute, from the container, to the outlet 6 through a supply duct 7, which passes through the rod 5, and the channel of distribution 4.
  • a rod control 5, of axis 15 intended for actuating means of conventional distribution systems, such as a distribution valve, or a distribution pump, allowing the fluid to be conveyed to distribute, from the container, to the outlet 6 through a supply duct 7, which passes through the rod 5, and the channel of distribution 4.
  • the axes 20 and 15, respectively of the nozzle and of the conduit 7, are orthogonal.
  • the duct 7 opens into the annular chamber 8 through a portion 7 a , tangential to said chamber 8; the arrangement is such that the rotation of the fluid, due to its tangential arrival in the chamber 8, corresponds to the direction of winding of the propeller represented by the helical distribution channel 4: thus, this rotation of the fluid is kept until the fluid leaves the dispensing nozzle.
  • the nozzle according to the invention minimizes pressure losses all along the path traveled by the fluid, despite the arrangement orthogonal of axes 20 and 15: in a simple application of the invention, axis 20 is at a distance from axis 15, as we can see in Figure 5, on which this distance has been exaggerated, on the scale of this figure. While minimizing, as we have just seen, the losses loads, the nozzle according to the invention also makes it possible to give the fluid a vortex movement which, as we know, promotes good distribution.
  • the variant nozzle according to the invention, of FIG. 2, comprises a centering core 3, of axis 20, which has a cylindrical part and a conical part, both adjusted in the bore 10 which has portions of corresponding shapes, respectively 10 b and 10 a , formed directly in the push-button, the conical portion 10 a opening to the outside according to the orifice 6.
  • the helical distribution channel 4 is, here too, hollowed out on the exterior surface of nucleus 3; the turns of the channel 4 which extend along the conical portion 10 a gradually approach the axis 20 towards the orifice 6, this leading to a further reduction in pressure losses.
  • the section of the channel 4 has the first turn begins at the right of the portion 7a of the duct 7 which allows the connection of said duct 7 to the channel 4; according to this variant, the section of the channel 4 gradually decreases from the turn 4 a to the last turn which opens into the conical portion 10 a in line with the channel 6: this gradual decrease in the section of the channel 4 makes it possible to compress the fluid gradually, which improves the distribution.
  • the part 7 a of connection of the channel 7 allows progressively to pass from the section of the conduit 7 to that of the turn 4 a , as seen in FIG. 2a.
  • the section of the duct 7 is equal to that of the first turn 4 a .
  • the channel of distribution 4 is hollowed out at the interface between the core 3 and the bore 10, and extends helically.
  • the centering core is mounted in the bore with a clearance transverse, the distribution channel being constituted by said set transverse.
  • the push-button 1 carries a core 3 of revolution in the shape of a warhead whose cross section decreases regularly towards the outlet orifice 6 formed in the bottom of a sleeve 2 a secured to the push button 1 and whose internal bore 10 c has a shape complementary to that of the outer face of the ogival core 3 and is located at a distance therefrom: the clearance thus created between the core 3 and the sleeve 2 a constitutes the distribution channel 4; seen in Figure 4, indicated by 4a, the primer a coil in the zone where the portion 7a of the duct 7 joins the channel 4; a partial partition 14, connecting the centering core 3 to the bore 10 c , is arranged so as to prevent the fluid from turning on itself and to give it an axial component of movement towards the orifice: thus, the particles of the fluid have a generally helical movement towards the outlet, around the axis 20, without it being necessary to materialize a helical outlet channel.
  • the dispensing nozzle is double, that is to say it has two outlet orifices, with axes 201 and 202; the left half-nozzle of FIG. 6 is shown, in section, in FIG. 7 where one of the two orifices is seen, the orifice 61.
  • Each half-nozzle comprises a cylindrical centering core 31, carried by push button 1, and mounted, with transverse play, in a bore designated as a whole by the reference 100; said game transverse constitutes the distribution channel 41 (the channel of the other half-nozzle is designated by the reference 42 in Figure 6).
  • a part of the bore 100 is made in the push button and has a portion 171 of start of turn, in line with part 71 of connection from conduit 7 to channel 41, and a deflecting portion 181; the portions 171 and 181 allow, in combination with the partition 141 (the mark 142 designates in FIG. 6 the corresponding partition of the other half-nozzle), to put the fluid in rotation and to give it a component axial movement towards the outlet.
  • the supply duct 7 is extended in two parts 71, 72, for connection to the channels distribution 41, 42, separated by a partition 19; preferably, the section of duct 7 is equal to the sum of the maximum sections of channels 41, 42.
  • the other part of bore 100 consists of the surface internal of a sleeve 21, the bottom of which carries the orifice 61; this surface internal has a conical part 161, compressing the fluid before its exit.
  • Figure 8 is similar to that of Figures 6 and 7 but the core 31 is of ogival shape and the bore 100c of the sleeve 21 has a similar shape.
