Description

La présente invention a pour objet un poussoir de pompe de pulvérisation, ou vaporisateur, avec projection latérale, plus particulièrement destiné à fonctionner sous des pressions élevées, de l'ordre de 100 bars ou plus, et à un rythme répétitif rapide, tel que 50 fonctionnements par seconde (50 Hz) ou davantage, 100 ou 200 Hz par exemple.The subject of the present invention is a spray pump or vaporizer push-button 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.

Le poussoir est prévu pour être monté sur la tige du piston, appelée communément tige de soupape, de la pompe, constituée d'un tube creux commandant le piston, et par lequel tube est refoulé le produit à vaporiser. Dans la présente invention, le jet de pulvérisation est sensiblement perpendiculaire à l'axe de la tige de soupape.The plunger is designed to be mounted on the piston rod, commonly called the valve rod, of the pump, consisting of a hollow tube controlling the piston, and through which tube is discharged the product to be vaporized. In the present invention, the spray jet is substantially perpendicular to the axis of the valve stem.

L'invention a pour but de limiter les vibrations qui peuvent apparaître dans un tel poussoir à projection latérale qui est actionnée à un rythme rapide.The object of the invention is to limit the vibrations which may appear in such a lateral projection pusher which is actuated at a rapid rate.

L'invention a donc pour objet un poussoir avec gicleur, pour être monté sur la tige de soupape d'une pompe de pulvérisation de liquide, destiné plus particulièrement à fonctionner sous des pressions très élevées, de l'ordre de 50 bars ou davantage, en particulier plus de 100 bars, et de façon répétitive très rapide, de l'ordre de 50 Hz ou davantage, ledit gicleur étant fixé au poussoir, ledit poussoir comportant un canal de sortie cylindrique qui s'étend axialement entre une extrémité avant et une extrémité arrière, caractérisé en ce que ledit canal de sortie (4) est perpendiculaire à l'axe de ladite tige de soupape, et en ce que le centre de gravité du poussoir avec le gicleur est situé sur l'axe de la tige de soupape.The subject of the invention is therefore a pusher with nozzle, to be mounted on the valve stem of a liquid spraying pump, intended more particularly to operate under very high pressures, of the order of 50 bars or more, in particular more than 100 bars, and repetitively very rapidly, of the order of 50 Hz or more, said nozzle being fixed to the pusher, said pusher comprising a cylindrical outlet channel which extends axially between a front end and a rear end, characterized in that said outlet channel (4) is perpendicular to the axis of said valve stem, and in that the center of gravity of the valve lifter with the nozzle is located on the axis of the valve stem .

Selon une autre caractéristique de l'invention, le poussoir comporte un orifice d'entrée qui est adapté à communiquer avec ladite tige de la pompe et qui débouche dans ledit canal de sortie dans une zone médiane, entre l'extrémité avant et l'extrémité arrière dudit canal de sortie, le canal de sortie est ouvert à son extrémité arrière et limité à son extrémité avant par une paroi frontale percée d'un orifice de sortie central, le gicleur a la forme d'une tige engagée dans le canal de sortie en laissant un passage de faible section entre la tige de soupape et l'orifice de sortie, et ledit gicleur est fixé dans le canal de sortie et obture l'extrémité arrière dudit canal de sortie. Cette disposition supprime le risque d'expulsion du gicleur vers l'avant, risque non négligeable quand la pression est élevée, et favorise le moulage du poussoir, permettant le moulage en une seule pièce d'un canal de grande longueur. Un gicleur du type général de celui de l'invention, dit gicleur interne, est divulgué dans le document FR-A--2 547 737. Ce document divulgue un poussoir ayant un canal coaxial à la tige de soupape de la pompe, ledit canal étant délimité à une extrémité de projection, ou extrémité avant, par une paroi percée d'un orifice central. Une tige, de section extérieure légèrement inférieure à la section intérieure du canal, est placée dans le canal, dont il ne reste qu'une section libre de volume réduit, en évitant ainsi un volume mort préjudiciable à une bonne pulvérisation. Dans le document FR-A-2 547 737, toutefois, l'extrémité arrière du canal du poussoir est ouverte et communique avec la tige de soupape de la pompe.According to another characteristic of the invention, the pusher has an inlet orifice which is adapted to communicate with said pump rod and which opens into said outlet channel in a middle zone, between the front end and the end rear of said outlet channel, the outlet channel is open at its rear end and limited at its front end by a front wall pierced with a central outlet port, the nozzle has the shape of a rod engaged in the outlet channel leaving a small section passage between the valve stem and the outlet, and said nozzle is fixed in the outlet channel and closes the rear end of said outlet channel. This arrangement eliminates the risk of expulsion of the nozzle forwards, a non-negligible risk when the pressure is high, and favors the molding of the pusher, allowing the molding in one piece of a very long channel. A nozzle of the general type of that of the invention, called an internal nozzle, is disclosed in document FR-A - 2 547 737. This document discloses a valve having a channel coaxial with the valve stem of the pump, said channel being delimited at a projection end, or front end, by a wall pierced with a central orifice. A rod, of slightly outer section lower than the inner section of the channel, is placed in the channel, of which there remains only a free section of reduced volume, thus avoiding a dead volume detrimental to good spraying. In document FR-A-2 547 737, however, the rear end of the pusher channel is open and communicates with the valve stem of the pump.

Avantageusement, le gicleur comporte une extrémité arrière dotée d'au moins deux joncs d'accrochage, chaque jonc d'accrochage étant constitué par un bourrelet périphérique formé sur le gicleur dans une section droite du gicleur, la section du bourrelet ayant la forme d'un cran orienté vers l'arrière du gicleur.Advantageously, the nozzle has a rear end provided with at least two attachment rods, each attachment rod being constituted by a peripheral bead formed on the nozzle in a straight section of the nozzle, the section of the bead having the shape of a notch oriented towards the rear of the nozzle.

Avantageusement, le gicleur comporte une extrémité avant disposée au voisinage de la paroi frontale du poussoir, l'extrémité avant du gicleur a un diamètre inférieur au diamètre du canal de sortie, et ledit canal de sortie comporte à son extrémité des bossages de centrage internes qui reçoivent et centrent l'extrémité avant du gicleur.Advantageously, the nozzle has a front end disposed in the vicinity of the front wall of the pusher, the front end of the nozzle has a diameter less than the diameter of the outlet channel, and said outlet channel has at its end internal centering bosses which receive and center the front end of the nozzle.

Avantageusement, le canal de sortie a un diamètre inférieur à 3 mm, de préférence compris entre 2 et 3 mm.Advantageously, the outlet channel has a diameter of less than 3 mm, preferably between 2 and 3 mm.

Selon une caractéristique importante de la présente invention, le centre de gravité du poussoir est situé dans l'axe de la tige de soupape. Cette disposition assure un bon équlibre et un bon maintien en position lors des fonctionnements répétitifs à cadence rapide. Selon une autre caractéristique importante de la présente invention, le canal de sortie du bouton poussoir, dans lequel débouche la tige de soupape a un diamètre réduit, au maximum de l'ordre de 3 mm, et de préférence entre 2 et 3 mm, ce qui permet de résister aux pressions élevées de fonctionnement tout en conservant des dimensions réduites.According to an important characteristic of the present invention, 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. According to another important characteristic of the present invention, 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.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre, donnée à titre d'exemple non limitatif, en regard des dessins ci-joints, et qui fera bien comprendre comment l'invention peut être réalisée.Other characteristics and advantages of the invention will appear during the description which follows, given by way of nonlimiting example, with reference to the attached drawings, and which will make it clear how the invention can be implemented.

  • Figure 5 is an enlarged view of a detail of the nozzle.

Les dessins représentent un mode de réalisation d'un poussoir 1 et d'un gicleur 2. Le poussoir comporte un embout de raccordement 3 formé de façon à emmancher le poussoir, de façon bien connue, sur la tige de soupape d'une pompe de pulvérisation. L'embout débouche dans un canal de sortie 4 sensiblement perpendiculaire à l'axe de l'embout, (qui est celui de la tige de soupape). Le canal 4 est limité à son extrémité avant 4A (ou de sortie du jet de pulvérisation) par une paroi frontale 5, percée en son centre d'un trou de pulvérisation 6.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.

L'extrémité arrière 4B est ouverte. Cette disposition permet de placer le poussoir sur une pompe montée sur un bidon, avec un orifice de pulvérisation 6 qui se trouve à l'extérieur du prolongement du bidon. La section du canal 4 peut être uniforme.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.

Cependant, afin de faciliter le démoulage, le canal peut être légèrement cônique en s'évasant vers l'extrémité ouverte 4B.However, in order to facilitate demolding, the channel may be slightly conical by widening towards the open end 4B.

Afin de résister dans des conditions favorables à des pressions qui peuvent être instantanément très élevées, par exemple 100 bars ou davantage, le diamètre du canal 4 est réduit conformément à une caractéristique de la présente invention, et ne dépasse pas sensiblement trois millimètres. Il est avantageusement compris entre deux et trois millimètres. La disposition avec gicleur interne permet de mouler dans de bonnes conditions un poussoir avec un canal de sortie assez long pour atteindre ou dépasser le prolongement du profil du bidon, et d'un diamètre adapté à recevoir un gicleur interne.In order to withstand favorable conditions at pressures which can be instantly very high, for example 100 bars or more, 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.

Selon une caractéristique importante de l'invention, le centre de gravité du poussoir avec le gicleur est situé sur l'axe de la tige de soupape, c'est-à-dire sur l'axe X de l'embout d'emmanchement 3. cette disposition est favorable au mouvement répétitif rapide du poussoir pour actionner la pompe à cadence élevée, au moins 50 Hz, et le cas échéant 100 Hz ou davantage.According to an important characteristic of the invention, 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.

Le gicleur 2 représenté sur la figure 4 est adapté à être logé sur le canal de sortie 4, de façon à laisser un passage de section réduite entre l'orifice 7 par lequel l'embout 3 débouche dans le canal 4 et l'extrémité avant 4A de ce canal, et de façon à obturer l'ouverture de l'autre extrémité 4B.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.

Pour assurer l'obturation, le gicleur tel que représenté est formé avec cinq joncs d'accrochage 8 dont un est représenté en coupe à plus grande échelle sur la figure 5. Chaque jonc est constitué par un bourrelet périphérique, faisant le tour du gicleur suivant une section droite de celui-ci. La section du bourrelet a la forme d'un cran 9 avec une arrête 10 orientée vers l'arrière. Ces joncs assurent d'une part l'étanchéité à l'intérieur du canal de sortie, et d'autre part le maintien en place du gicleur dans le canal. La présence de plusieurs joncs permet de tenir à des pressions très élevées.To ensure obturation, 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. These rods ensure on the one hand the sealing to inside the outlet channel, and on the other hand keeping the nozzle in place in the channel. The presence of several rods makes it possible to withstand very high pressures.

On a pu constater expérimentalement qu'un jonc tel que représenté pouvait résister à une pression de 40 bars. En principe, cinq joncs peuvent résister à une pression de 200 bars.It has been found experimentally that a rod as shown could withstand a pressure of 40 bars. In principle, five rods can withstand a pressure of 200 bars.

Afin d'obtenir une section de passage définie entre l'orifice 7 et le trou de pulvérisation 6, la partie avant 2A du gicleur a un diamètre légèrement inférieur au diamètre intérieur du canal 4, et celui-ci est formé, au voisinage de son extrémité avant, avec au moins trois bossages de centrage 11, définissant ainsi autant de passages entre le gicleur et la paroi du canal entre les bossages. Ceux-ci ont une épaisseur constante sauf un biseau d'extrémité pour faciliter l'introduction du gicleur jusqu'au fond de son logement.In order to obtain a passage section defined between the orifice 7 and the spray hole 6, 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.

La paroi frontale 5 est munie, de façon classique, sur sa face interne, de rainures s'étendant depuis la périphérie entre les bossages de centrage 11, jusqu'à l'orifice de sortie 6, arrivant tangentiellement à celui-ci, pour imprimer au fluide expulsé un mouvement tourbillonnaire.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.

En plus de la fixation par les joncs, le gicleur peut être soudé au poussoir une fois qu'il est mis en place.In addition to the fixing by the rods, the nozzle can be welded to the pusher once it is put in place.

Un poussoir selon l'invention permet de faire fonctionner une pompe de pulvérisation à cadence élevée et sous forte pression, donnant une pulvérisation très fine et un débit qui apparaît en pratique comme constant, ce qui donne un effet identique à celui d'un aérosol, ou même meilleur, sans avoir les inconvénients de l'emploi d'un produit auxiliaire pouvant être considéré comme défavorable à l'environnement.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.
