Abstract

The invention relates to a regulating nozzle for water jets. It comprises a plurality of coaxial tubes 1-4, at least some, 3, 4, of the said tubes being mounted so as to slide axially in relation to at least some others, 1, 2, of the said tubes.

Description

La présente invention concerne un ajutage pour jets d'eau, et vise plus particulierement à fournir des jets d'eau variables en amplitude
et en forme.
The present invention relates to a nozzle for water jets, and more particularly aims to provide water jets varying in amplitude
and fit.

A cet effet, l'invention a pour objet un ajutage pour jets
d'eau, caractérisé par le fait qu'il comprend une pluralité de tubes
coaxiaux, au moins certains desdits tubes étant montés coulissants axialement par rapport à au moins certains autres desdits tubes.
To this end, the invention relates to a nozzle for jets
of water, characterized in that it comprises a plurality of tubes
coaxial, at least some of said tubes being slidably mounted axially with respect to at least some others of said tubes.

Le tube central peut par conséquent fournir un jet vertical
éventuellement variable en hauteur tandis que les conduits annulaires
compris entre les différents tubes forment des vasques dont 1' évasement varie en fonction de la hauteur relative des extrémités des tubes formant chacun de ces conduits annulaires.
The central tube can therefore provide a vertical jet
possibly variable in height while the annular conduits
between the different tubes form sinks, the flaring of which varies as a function of the relative height of the ends of the tubes forming each of these annular conduits.

Les tubes intérieur et extérieur peuvent être fixes, le tube intérieur débouchant à une hauteur supérieure à celle à laquelle débouche le tube extérieur. The inner and outer tubes can be fixed, the inner tube opening at a height greater than that at which the outer tube opens.

Plus particulièrement, on peut prévoir deux tubes intermédiaires coulissant axialement indépendamment l'un de l'autre. More particularly, it is possible to provide two intermediate tubes sliding axially independently of one another.

Dans ce dernier cas, on peut prévoir des moyens pour alimenter en eau sous pression, d'une part, le tube central et vautre part, les espaces annulaires compris entre le tube extérieur et le plus extérieur des tubes intermédiaires et, respectivement, entre les deux tubes intermédiaires. In the latter case, means may be provided for supplying pressurized water, on the one hand, to the central tube and, on the other hand, the annular spaces comprised between the outer tube and the outermost of the intermediate tubes and, respectively, between the two intermediate tubes.

On décrira maintenant à titre d'exemple non limitatif un mode de réalisation particulier de l'invention en référence aux dessins schématiques annexés dans lesquels
- la figure 1 est une vue en coupe axiale d'un ajutage selon l'invention et de ses moyens de commande, et
- les figures 2 à 13 illustrent différentes formes de jets d'eau susceptibles d'être obtenus avec ajutage de la figure I.
A particular embodiment of the invention will now be described by way of nonlimiting example with reference to the appended schematic drawings in which
FIG. 1 is a view in axial section of a nozzle according to the invention and of its control means, and
- Figures 2 to 13 illustrate different forms of water jets that can be obtained with the nozzle of Figure I.

La figure 1 montre un ajutage composé de quatre tubes coaxiaux, à savoir un tube intérieur I, un tube extérieur 2, un tube intermédiaire 3 adjacent au tube I et un deuxième tube intermédiaire 4 disposé entre les tubes 2 et 3. FIG. 1 shows a nozzle composed of four coaxial tubes, namely an inner tube I, an outer tube 2, an intermediate tube 3 adjacent to the tube I and a second intermediate tube 4 disposed between the tubes 2 and 3.

Les tubes 1 et 2 sont fixes, le tube l débouchant au-dessus du tube 2, c'est-à-dire que l'extrémité du tube 1 dépasse du tube 2. The tubes 1 and 2 are fixed, the tube 1 emerging above the tube 2, that is to say that the end of the tube 1 protrudes from the tube 2.

Par contre, les tubes 3 et 4 sont mobiles axialement à l'aide de dispositifs 5 et 6 respectivement qui peuvent être conStitués de tous moyens connus hydrauliques, électriques ou mécaniques par exemple, tels que des vérins, des cames, des bielles, des crémaillères etc...  On the other hand, the tubes 3 and 4 are axially movable by means of devices 5 and 6 respectively which can be made up of any known hydraulic, electrical or mechanical means for example, such as jacks, cams, connecting rods, racks etc ...

Le tube 1 est alimenté à l'aide d'une pompe 7, (ou tout autre
source sous pression dont on peut faire varier le débit ou la pression par un moyen quelconque) l'espace annulaire compris entre les tubes mobiles 3 et
4 est alimenté à l'aide d'une pompe 8 et l'espace annulaire compris entre
les tubes 2 et 4 est alimenté à l'aide d'une pompe 9.
The tube 1 is supplied with the aid of a pump 7, (or any other
pressure source whose flow or pressure can be varied by any means) the annular space between the movable tubes 3 and
4 is supplied using a pump 8 and the annular space between
the tubes 2 and 4 is supplied using a pump 9.

Les pompes 7, 8 et 9 ont des vitesses variables obtenues par
exemple grâce à des moteurs asservis par des variateurs de vitesse.
Pumps 7, 8 and 9 have variable speeds obtained by
example thanks to motors controlled by variable speed drives.

Les pompes à vitesse variable 7 à 9 permettent de régler la puissance et le débit des jets, et notamment leur hauteur lorsque ceux-ci
sont verticaux, alors que les dispositifs de réglage 5 et 6 ont pour
fonction de régler la forme des jets par un déplacement axial convenable des
tubes 3 et 4.
Variable speed pumps 7 to 9 adjust the power and flow of the jets, and in particular their height when they are
are vertical, while the adjustment devices 5 and 6 have for
function of adjusting the shape of the jets by a suitable axial displacement of the
tubes 3 and 4.

Un joint torique (non représenté) ou tout autre moyen
fournissant une étanchéité entre les différents tubes peut être disposé entre les tubes 1 et 3 afin d'éviter que de l'eau ne pénètre dans l-'espace annulaire déterminé entre ces deux tubes.
An O-ring (not shown) or any other means
providing a seal between the different tubes can be arranged between the tubes 1 and 3 in order to prevent water from entering the annular space determined between these two tubes.

La figure 2 représente le cas où seul le tube 1 est alimenté par la pompe 7 de manière à former un jet'vertical 10 dont la hauteur est fonction de la vitesse de rotation de la pompe 7. FIG. 2 represents the case where only the tube 1 is supplied by the pump 7 so as to form a vertical jet 10 whose height is a function of the speed of rotation of the pump 7.

Les figures 3 à 5 représentent le cas où seul le conduit annulaire compris entre les tubes 3 et 4 est alimenté par la pompe â, les pompes 7 et 9 étant arrêtées. Figures 3 to 5 show the case where only the annular conduit between the tubes 3 and 4 is supplied by the pump â, the pumps 7 and 9 being stopped.

Ces figures représentent le cas où le tube 4 est fixe comme les tubes 1 et 2, seul le tube 3 étant déplacé de bas en haut à l'aide du dispositif 5. These figures represent the case where the tube 4 is fixed like the tubes 1 and 2, only the tube 3 being moved from bottom to top using the device 5.

Dans la position la plus basse du tube 3, on obtient le jet vertical Il représenté à la figure 3, la figure 5 représentant au contraire le tube 3 dans sa position la plus haute donnant la vasque 12 la plus évasée possible. In the lowest position of the tube 3, the vertical jet II obtained in FIG. 3 is obtained, FIG. 5 on the contrary representing the tube 3 in its highest position giving the basin 12 as flared as possible.

Dans la position intermédiaire de la figure 4, le tube 3 débouche à la même hauteur que les tubes 2 et 4 et donne une vasque 13 d'évasement moyen. In the intermediate position of Figure 4, the tube 3 opens at the same height as the tubes 2 and 4 and gives a basin 13 of average flare.

Les figures 6, 7 et 8 correspondent au cas des figures 3, 4 et 5 respectivement dans le cas où seule la pompe 9 est entraLnée pour alimenter le conduit annulaire compris entre les tubes 2 et 4, les tubes I, 2 et 3 étant fixes et le tube 4 étant seul mobile à l'aide du dispositif 6. Figures 6, 7 and 8 correspond to the case of Figures 3, 4 and 5 respectively in the case where only the pump 9 is driven to supply the annular conduit between the tubes 2 and 4, the tubes I, 2 and 3 being fixed and the tube 4 being the only mobile using the device 6.

Comme précédemment, on obtient un jet vertical 14 pour la position la plus basse du tube 4, une vasque 15 d'évasement moyen lorsque le tube 4 est dans une position où il débouche à la même hauteur que les tubes 2 et 3 et une vasque 16 d'évasement maximum lorsque le tube 4 est dans sa position la plus haute, c'est-à-dire lorsqutil débouche à une hauteur comprise entre celle des tubes I et 2. As before, a vertical jet 14 is obtained for the lowest position of the tube 4, a basin 15 of average flaring when the tube 4 is in a position where it opens at the same height as the tubes 2 and 3 and a basin 16 maximum flaring when the tube 4 is in its highest position, that is to say when it opens at a height between that of the tubes I and 2.

Les figures 9 à 13 représentent le cas où les trois pompes 7 à 9 sont entraînées en rotation et alimentent les trois jets. Figures 9 to 13 show the case where the three pumps 7 to 9 are rotated and supply the three jets.

Dans les figures 9 à 11, seul le tube 4 est mobile, le tube 3 étant réglé de manière à donner un jet intermédiaire 17 vertical concentrique au jet central 18. In FIGS. 9 to 11, only the tube 4 is mobile, the tube 3 being adjusted so as to give a vertical intermediate jet 17 concentric to the central jet 18.

Dans le cas de la figure 9, le jet extérieur 19 est egalement vertical et dans le cas des figures 10 et II, on obtient un jet extérieur 20, 21 respectivement de plus en plus évasé au fur et à mesure de la remontée du tube 4. In the case of FIG. 9, the external jet 19 is also vertical and in the case of FIGS. 10 and II, an external jet 20, 21 is obtained, respectively more and more flared as the tube 4 rises. .

Dans le cas des figures 12 et 13, les deux tubes 3 et 4 sont mobiles de manière à former deux vasques extérieures 22 et 23 autour d'un jet central 24 vertical, les vasques 22 et 23 étant de plus en plus évasées au fur et à mesure de la remontée des tubes 3 et 4. In the case of FIGS. 12 and 13, the two tubes 3 and 4 are movable so as to form two external bowls 22 and 23 around a vertical central jet 24, the bowls 22 and 23 being more and more flared as and as the tubes 3 and 4 rise.

Diverses variantes et modifications peuvent bien entendu être apportées à la description qui précède sans sortir pour- autant du cadre ni de l'esprit de l'invention.  Various variants and modifications can of course be made to the above description without, however, departing from the scope or the spirit of the invention.
