Definitions

  • the subject of the present invention is a spray pump or vaporizer pusher with lateral projection, more particularly intended to operate under high pressures, of the order of 100 bars or more, and at a rapid repetitive rate, such as 50 operations per second (50 Hz) or more, 100 or 200 Hz for example.
  • the invention relates more particularly to so-called internal sprinklers. Such a nozzle is described inter alia in French Patent No.
  • 2,547,737 is constituted by the association of a channel, delimited at a projection end, or front end, by a wall pierced with a central orifice and d 'A rod of outer section slightly smaller than the inner section of the channel, placed in the channel, of which there remains only a free section of reduced volume, thereby avoiding a dead volume detrimental to good spraying.
  • This arrangement eliminates the risk of expulsion towards the front of the nozzle, a non-negligible risk when the pressure is high, and promotes the molding of the pusher, allowing the molding in one piece of a very long channel.
  • a pusher is provided to be mounted on the piston rod, commonly called valve stem, of the pump, consisting of a hollow tube controlling the piston, and through which tube is discharged the product to be vaporized.
  • the spray jet is substantially perpendicular to the axis of the valve stem.
  • the center of gravity of the tappet is located in the axis of the valve stem. This arrangement ensures a good balance and a good holding in position during repetitive operations at a rapid rate.
  • the outlet channel of the push button, into which the valve stem opens has a reduced diameter, at most of the order of 3 mm, and preferably between 2 and 3 mm, this which makes it possible to withstand the high operating pressures while retaining reduced dimensions.
  • the drawings represent an embodiment of a pusher 1 and a nozzle 2.
  • the pusher comprises a connection end piece 3 formed so as to press the pusher, in a well known manner, on the valve stem of a pump. spray.
  • the nozzle opens into an outlet channel 4 substantially perpendicular to the axis of the nozzle, (which is that of the valve stem).
  • the channel 4 is limited at its front end 4A (or outlet from the spray jet) by a front wall 5, pierced in its center with a spray hole 6.
  • the rear end 4B is open. This arrangement makes it possible to place the pusher on a pump mounted on a container, with a spray orifice 6 which is located outside the extension of the container.
  • the section of channel 4 can be uniform.
  • the channel may be slightly conical by widening towards the open end 4B.
  • the diameter of the channel 4 is reduced in accordance with a characteristic of the present invention, and does not exceed substantially three millimeters. It is advantageously between two and three millimeters.
  • the arrangement with internal nozzle makes it possible to mold in good conditions a pusher with an outlet channel long enough to reach or exceed the extension of the profile of the container, and of a diameter suitable for receiving an internal nozzle.
  • the center of gravity of the pusher with the nozzle is located on the axis of the valve stem, that is to say on the X axis of the fitting 3 this arrangement is favorable to rapid repetitive movement of the pusher to actuate the pump at a high rate, at least 50 Hz, and if necessary 100 Hz or more.
  • the nozzle 2 shown in Figure 4 is adapted to be housed on the outlet channel 4, so as to leave a passage of reduced section between the orifice 7 through which the endpiece 3 opens into the channel 4 and the front end 4A of this channel, and so as to close the opening of the other end 4B.
  • the nozzle as shown is formed with five attachment rods 8, one of which is shown in section on a larger scale in FIG. 5.
  • Each rod is constituted by a peripheral bead, going around the following nozzle a cross section of it.
  • the section of the bead has the shape of a notch 9 with a stop 10 oriented towards the rear.
  • the front part 2A of the nozzle has a diameter slightly smaller than the inside diameter of the channel 4, and the latter is formed, in the vicinity of its front end, with at least three centering bosses 11, thus defining as many passages between the nozzle and the wall of the channel between the bosses. These have a constant thickness except for an end bevel to facilitate the introduction of the nozzle to the bottom of its housing.
  • the front wall 5 is provided, in a conventional manner, on its internal face, with grooves extending from the periphery between the centering bosses 11, up to the outlet orifice 6, arriving tangentially thereto, for printing to the expelled fluid a vortex movement.
  • the nozzle can be welded to the pusher once it is put in place.
  • a pusher according to the invention makes it possible to operate a spray pump at a high rate and under high pressure, giving a very fine spray and a flow which appears in practice to be constant, which gives an effect identical to that of an aerosol, or even better, without having the drawbacks of using an auxiliary product which can be considered unfavorable for the environment.
