Definitions

  • the subject of the present invention is a thrust regulator of the kind defined in the preamble of claim 1.
  • This thrust resulting from the pressure which acts on the surface of a medium inside a receptacle, for example an aerosol can , in order to maintain at least approximately constant the flow rate of this medium per unit of time during the expulsion of the latter out of the container and this non-obstant a pressure drop, proportional to the volume of this expelled medium, when the source of pressure consists of a compressed gas, for example air or nitrogen.
  • the differential piston is supported on a spring which is calibrated so that under the action of the pressure of the container of a predetermined value, it is compressed so that the differential piston takes a first end position, by which it reduces the passage section of the evacuation channel to a minimum section and that in proportion to the pressure drop, following the evacuation of medium from the container, the spring expands and displaces the piston so that this results in a progressive enlargement of the passage section of the evacuation channel until the piston reaches a second end of travel, as soon as a minimum pressure, predetermined, settles in the container.
  • the shape of the piston relative to that of the evacuation channel is chosen so that by its displacement it ensures that the sum resulting from the multiplication of the pressure of the container by the remaining passage section, remains, at least approximately, constant.
  • Each of the embodiments proposed in this European application has shortcomings and disadvantages, such as too high permeability of the membranes at vapor pressure, too high price of parts injected in synthetic materials due to the pressure required, regulation and consequently jerky spraying. due to an axial back and forth movement of the differential piston.
  • the object of the present invention is to provide a regulator which makes it possible, together with the nozzle as described in the aforementioned American patent, to obtain a constant flow rate per unit of time non-obstant the pressure drop in an aerosol container having as propellant a compressed gas such as nitrogen and air settling in as the box is emptied of its contents.
  • the pusher 6 is provided with a cage 1 which has a breakthrough with a large diameter 39, a diameter 40 and a small diameter 50 which leads to a channel 60 to supply a nozzle 5.
  • a piston differential 2 whose upstream side has a large diameter 14 with the chamber 17 which serves as a fulcrum for the column of the medium 18, while its downstream side has a small diameter 12 and one end 12a having an aerodynamic form of reduction of turbulence.
  • a distance "A" Between the upstream edge 61 of the channel 60 and the end 12a of the piston 2 is a distance "A".
  • This distance “A” must be large enough so that the turbulence which is created around the end 12a, despite its aerodynamic shape, when the latter is too close to the channel 60, can agglomerate, in order to constitute a flow laminar before reaching the upstream edge 61 of the channel 60.
  • the small diameter 50 of the cage 1 has, opposite the entrance to the channel 60, a curved wall 41, intended to eliminate the formation of other turbulences by angles, on the contrary, to facilitate the flow of the laminar flow towards the nozzle 5.
  • the piston 2 is provided with the bearing surface 15 of the spring 3 and the grooves 16 and 16a through which the medium 18 can flow, even if the spring 3 is compressed to block and forming a sealed wall.
  • the bearing surface 15 also serves as a stop for limiting the stroke of the piston 2, when the latter is moved downstream by the medium 18 under the highest expulsion pressure.
  • the spring 3 expands and pushes the piston 2 upstream where its stroke is limited by the clamping sleeve 20 which adapts to the piston 3 $ of a valve aerosol not shown located inside the ferrule 31.
  • the ferrule 31 On its periphery the ferrule 31 carries the chimney 53 which serves as axial guide to the pusher 6 to avoid a too pronounced tilting, tilting which is inevitable due to the length of the pusher , whose only point of support is the piston 35 which, not being for technical reasons not too guided, promotes an undesirable tilting.
  • Fig. 2 shows the second embodiment of the device according to the invention housed in a pusher 6 which serves as an opening element of the valve 25, which consists of the body 26, the seat 27, the inner seal 28, the seal outside 29, spring 30 and ferrule 31.
  • a dip tube is not shown.
  • the pusher 6 has the rod 32, provided with the line 33, parallel to the axis of the rod 32 and the line 34, perpendicular to the line 33.
  • the rod 32 is inserted in the seat 26 of the valve 25 so that the seat 26 closes off the inlet of the pipe 33.
  • the pipe 34 is placed so that its inlet is inserted in the upper part of the joint 28. This arrangement of the pipes 33 and 34 is imposed by the fact that no experienced commercial aerosol valve is waterproof immediately after closing the valve after use.
  • the propellant is a soluble gas such as FREON etc.
  • FREON a soluble gas
  • the expelled medium contains no factor which, by its force of expansion in contact with the atmospheric pressure would instantly evaporate the medium which still flows from the valve after it has closed and there is a flow of medium at nozzle 5 which can last up to twenty seconds after the valve has closed. This flow is eliminated by the arrangement of the pipes 33 and 34 of the pusher 6.
  • valve 25 has simply become sealed, the inlet of the pipe 34 being placed in the seal 28 which therefore closes it, does not allow more in the medium, still flowing in the seat 26, to penetrate into the pipe 34, the pipe 33 being, as already described, closed by the seal 28.
  • the turbulence As they are perpendicular to the channel 8a of the cylinder 1 there is caused at the outlet from the grooves 24 turbulence, the change in direction of the flow in a perpendicular manner being at the base of the obstructing turbulence observed. Because the grooves 24 are tangential with respect to the chamber 23, the flow of the medium 18, although turbulent, is subjected to a direction of rotary flow, perpetuated by the ciruclar edge 19 which transforms the turbulent flow into laminar flow which finally feeds the nozzle 5 through the channels 21. Because the turbulence is transformed in laminar flow, they only constitute a braking force which is all the stronger as the pressure of the medium is high, but without being able to reach a force for blocking the flow.
  • the braking, imparted to the flow of the medium 18 by the turbulence, is, in this embodiment of the regulator, a part of the regulation of the flow per unit of time, the spring 3 not intervening immediately but only, when the thrust of the medium 18 decreases to the point that the spring 3 can relax and open the passage section at all levels of the bearings of the piston 2.
  • the rod 32 of the pusher 6 has a large diameter 32a, with which it rests on the seal 28, the pipe 34 being located immediately below the diameter 32a.
  • Line 34 does not have a round section, but rectangular. Therefore, when the pusher 6 is moved downward to open the valve 25, it remains closed for longer by the seal 28 than a round pipe which, for a section of identical size, must have a diameter such that '' part of the inlet is already disengaged from the seal 28, without the valve 25 being sufficiently open to release all the pressure, under which the medium 18 is located, while a rectangular pipe 34, of a predetermined height , requires on the one hand a larger path for movement of the pusher 6 so that its entry is clear of the joint 28 and on the other hand, instead of presenting as a inlet a small part of its section, as is the case for a round pipe, according to this predetermined height, the pipe 34 presents its entire inlet section at medium 18 which, thanks to the optimum opening of the valve 25, due to the larger path made by the pusher 6
  • the piston 2 has the chamber 17 which serves as a fulcrum for the medium 18, which ensures effective displacement of the piston 2 under the action of pressure, under which the medium 18 is located.
  • the force of the spring 3 is chosen so that the initial pressure of 5 bar of a medium 18 is fully compressed to allow the piston 2 to press firmly against the core 4 which therefore serves as a limit switch piston 2.
  • the core 4 is inserted into the nozzle 5 so that it forms with the edge 19 thereof a depression 19a, from which the channels supply 21 of the nozzle 5.
  • the upstream face of the core 4 carries the protrusions 22, the center of which presents the chamber 23, from which multiple grooves 24 emerge, each of which forms a tangent with the circumference of the chamber 23.
  • Line 45 represents the flow per unit of time, when using a commercially available nozzle
  • line 36 shows the flow per unit of time, obtained when using the nozzle according to US Pat. No. 4,260,110
  • the author of the present invention and line 37 illustrates the flow rate per unit of time obtained by using the regulator according to the invention with the aforementioned nozzle.
