Definitions

  • the present invention relates to a thrust regulator according to the preamble of claim 1 in order to maintain constant at least approximately the flow rate of the product per unit of time during the expulsion of the latter out of the container, and this notwithstanding the fall of pressure which is proportional to the volume of product expelled, when the pressure source consists of a propellant such as a compressed gas, for example air or nitrogen.
  • a propellant such as a compressed gas, for example air or nitrogen.
  • the aforementioned European patent application proposes a thrust regulator, with the aid of which the flow rate per unit of time d is kept at least approximately constant.
  • a product expelled from a pressure container notwithstanding the pressure drop acting on the product inside the container.
  • This regulator has, in an evacuation channel, a differential piston, the dimension of which relative to that of the evacuation channel is such that a minimum passage section for the evacuation of the product remains at all times of the expulsion.
  • the differential piston has surfaces of different dimensions at the ends, the largest surface being opposite the flow of the product.
  • a spring which is calibrated so that under the action of a pressure of a predetermined value in the container, it is compressed in order to take up a first end-of-travel position, by which it reduces the passage section of the evacuation channel to a minimum section and that in proportion to the pressure drop in the container, following the evacuation of the product from the container, the spring expands and displaces the piston, which results in an increase progressive of the passage section of the discharge channel, until the piston reaches a second end-of-travel position, as soon as a predetermined minimum pressure settles in the container.
  • the shape of the piston relative to that of the evacuation channel is chosen so that by its movement it ensures that the product resulting from the multiplication of the pressure in the container by the passage section of the evacuation channel remains, at less approximately, constant.
  • Each of the embodiments proposed in the aforementioned European application has shortcomings and disadvantages, such as too high permeability of the membranes at vapor pressure, too high price of the parts injected in synthetic material, due to the required rigidity and regulation and consequently a jerky spraying due to an axial back and forth movement of the differential piston.
  • the object of the present invention is to propose an improved regulator which makes it possible, in common with the nozzle as described in the aforementioned US Pat. as the container is emptied of its content in the aerosol container having as propellant a compressed gas such as nitrogen or air.
  • this object is achieved by a regulator as defined in claim 1.
  • a regulator as defined in claim 1.
  • Various characteristics of this regulator are included in the subclaims.
  • a pusher 6 is provided with a cage 1 which has an evacuation channel 8a with a large diameter section 39, a medium diameter section 40 and a small diameter section 50.
  • This evacuation channel opens into a supply channel 60 for a nozzle 5 and comprises a differential piston 2, the upstream side 14 of which has a large diameter, cooperating with the section of average diameter 40 and which has a chamber 17 which serves as a fulcrum for a column of a product 18, while its downstream side 12 has a small diameter and an end 12a having an aerodynamic shape to reduce the turbulence which can be created during the evacuation of the product 18 through the evacuation channel 8a.
  • An upstream lower edge 61 of the feed channel 60 is located at a distance A from the end 12a of the differential piston, a distance which must be large enough for the turbulence which is created around the end 12a, despite its shape aerodynamic, can agglomerate, in order to reach a laminar flow of the product 18, before the latter passes the upstream lower edge 61 of the supply channel 60.
  • the small diameter section 50 of the discharge channel of the cage 1 has, opposite the inlet of the feed channel 60, a curved wall 41, intended to prevent the formation of other turbulences, for example created by angles, and to facilitate the flow of the laminar flow of the product 18 towards the nozzle 5.
  • the differential piston 2 is provided with a shoulder 15, on which a spring 3 rests, and grooves 16 and 16a, through which the product 18 can flow, even on the differential piston 2 occupies a first downstream end position in which the spring is fully compressed.
  • the shoulder 15 also serves as a stop for limiting the stroke of the differential piston 2, when the latter is moved downstream by the product 18 under the highest expulsion pressure which may prevail in the container.
  • the spring 3 expands and pushes the differential piston in the upstream direction, until it reaches a second end-of-travel position in which it is supported by a clamping sleeve 20 which is fitted on a piston 35 of an aerosol valve not shown located inside a ferrule 31.
  • the ferrule 31 On its periphery the ferrule 31 carries a chimney 53 which serves as axial guidance for a pusher 6 , in order to avoid an overly pronounced tilting of the latter.
  • a slight tilting is inevitable, because the length of the pusher 6, the only fulcrum of which is the piston 35 which cannot be guided too much for technical reasons.
  • This annoying tilting could also be limited by means of a skirt attached to the socket 20 and which covers the ferrule 31.
  • the differential piston 2 When the pusher 6 is actuated for the first time after filling the container and therefore the product 18 is expelled from the latter with the strongest pressure, the differential piston 2 is moved in the downstream direction not only by the push of the product 18, but also by a suction force, created at the inlet of the feed channel 60 by the expansion of the product under pressure and by a swirl printed on the product 18. If the spring 3 would be calibrated solely according to the pushed from product 18 and not additionally as a function of this suction force, it is too weak to overcome, at the start of regulation, these two additional forces (suction force and swirl). The differential piston would therefore remain stationary and would not move upstream.
  • Fig. 2 shows a second preferred embodiment of the regulator according to the invention, housed in the pusher 6 which serves as an opening element of a valve 25 consisting of a body 26, a seat 27, a inner seal 28, an outer seal 29, a spring 30 and the ferrule 31, a dip tube not being shown.
  • the pusher 6 has a rod 32, provided with a pipe 33, parallel to the axis of the rod 32 and a perpendicular pipe 34.
  • the rod 32 is inserted into the seat 27 of the valve 25 by way of which the seat 27 closes the inlet of the pipe 33.
  • the perpendicular pipe 34 is placed so that its inlet is normally inserted in the upper part of the joint 28.
  • This design is essential especially in cases where the regulator according to the invention is used to spray products 18, an excessive amount of which at the outlet of the nozzle 5, while drying, could obstruct it.
  • FIG. 2 shows said second embodiment of the regulator according to the invention in the rest position, the spring 3 having pushed the differential piston 2 into its starting position, while FIG. 3 illustrates the position of the differential piston 2 during use, when the valve 25, not shown, is open and the product 18 flows under the highest pressure which may prevail in the container, also not shown.
  • the regulation takes place as explained with the aid of FIG. 4, as follows: as soon as the valve 25 is opened, the product 18 penetrates on the one hand into the chamber 17 of the differential piston 2 and on the other hand flows along the latter into the evacuation channel 8a. Under the pressure of the product 18 the differential piston 2 is pushed in the direction of the nozzle 5 in reverse of the force of the spring 3 which is compressed. The front face of the small diameter section 12 of the differential piston 2 is firmly pressed against the center of a core 4 which is part of the nozzle 5 and is housed on its upstream side, so that it enters a chamber 23, the volume of which it decreases.
  • Protrusions 22 of the core 4 and a circular edge 19 of the nozzle 5 are in firm contact with the cage 1, so that the product 18 under pressure can move towards the nozzle 5 only through grooves-conduits 24 of the core 4. As these are perpendicular to the discharge channel 8a, obstructive turbulence is caused at the outlet of the grooves-pipes 24. Because the grooves-conduits 24 are tangential with respect to the chamber 23, the flow of the product 18, although turbulent, is subjected to a rotary flow, perpetuated by the circular edge 19 which transforms the turbulent flow into laminar flow which feeds finally the nozzle 5 by channels 21. Because the turbulence is transformed into laminar flow, it no longer constitutes a braking force which is all the stronger as the pressure of the high product, but without being able to reach a force blocking the flow.
  • the braking, imparted to the flow of the product 18 by the obstructive turbulence is, in this execution of the regulator, in fact an essential part of the beginning of the regulation of the flow rate per unit of time. Indeed, the spring 3 must not move from the start of the evacuation of the product 18 the differential piston 2, but only, when the thrust of the product 18 decreases to a point where the passage section for the product 18 must be enlarged , so that an unchanged amount of product 18 can reach the nozzle 4 per unit of time.
  • the rod 32 of the pusher 6 must be provided with a large diameter 32a, with which it rests on the seal 28, the perpendicular pipe 34 being immediately below the diameter 32a and not having a round, but rectangular section. 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 its inlet is already disengaged from the seal 28, before the valve 25 is sufficiently open to release all the pressure, under which the product 18 is found.
  • the perpendicular pipe 34 is of rectangular section, it requires on the one hand, a path for the displacement of the pusher 6 which is larger so that its entry is clear of the seal 28 and on the other hand, instead of presenting as a entry a small part of its section, it presents almost instantaneously, but later, all of its product entry section 18 which is therefore expelled with all the pressure available, because the valve 25 is fully open, before the perpendicular pipe 34 is opened.
  • the regulator according to the invention as shown in detail in FIG. 4 is constituted by the cage 1, the differential piston 2, the spring 3 and the core 4 which can be made in one piece with the nozzle 5 and can be housed either in the pusher 6 or in a mounting cylinder 7, illustrated in fig. 6.
  • the discharge channel is formed by pipes 8, 9, 10 and 11.
  • the differential piston 2 is provided with grooves 16 and 16a.
  • the force of the spring 3 is preferably chosen so that if the product 18 is subjected to an initial pressure of 5 bar, the spring is compressed in block to allow the differential piston 2 to press firmly against the core 4.
  • the latter is preferably inserted into the nozzle 5, so that it forms with the edge 19 thereof a depression 19a, from which the supply channels 21 of the nozzle 5 start.
  • the upstream face of the core 4 carries the protuberances 22 and are center presents the chamber 23, from which leave the grooves-conduits 24, each of which forms tangent with the circumference of the chamber 23.
  • the upstream face of the protrusions 22 and the circular edge 19 of the nozzle 5 are in firm contact with the cage 1 , so that the grooves-conduits 24 become reellement of the conduits which connect the chamber 23 to the recess 19a which thus becomes an annular conduit from which the product 18 is introduced into the supply channels 21 of the nozzle 5.
  • FIG. 7 The regulation of the flow using the regulator according to the invention is illustrated in FIG. 7, the line 45 of which represents the flow of product 18 per unit of time, when a commercial nozzle is used, while the line 36 shows the flow per unit of time, obtained when a nozzle is used according to the American patent No. 4,260,110 alone.
  • Line 37 illustrates the flow rate per time unit obtained by using the regulator according to the invention in common with the aforementioned nozzle.
