Abstract
Description
L'objet de l'invention concerne un dispositif de turbine moteur hydraulique a haut rendement
Il est destiné à l'entrainement des outillages divers tournant à des vitesses élevées, telles les brosses ou autres, utilisées pour les travaux sous-marins.The object of the invention relates to a high efficiency hydraulic motor turbine device.
It is intended for the training of various tools rotating at high speeds, such as brushes or others, used for underwater work.
Dans tes dispositifs connus généralement utilises a ce jour, les éléments injecteurs agissant sur des secteurs de pâles curvilignes entrainaient des pertes d'énergies importantes provenant des résistances passives et turbulences anarchiques provoque se pas les angles de pro jections et surfaces réceptrices. In the known devices generally used to date, the injector elements acting on curvilinear pale sectors resulted in significant energy losses coming from passive resistances and uncontrolled turbulence causes not the angles of projections and receiving surfaces.
Le dispositif suivant l'invention supprime ces in convenients et permet d'obtenir un rendement maximum avec des pertes de puissances réduites. The device according to the invention eliminates these inconveniences and makes it possible to obtain maximum efficiency with reduced power losses.
Il se caractérise par la combinaison des profils d' injections dont les orient@tions et angles de projections débouchent sur des secteurs de pâles rectilignes formant surfaces de poussees a récupération intégrale de puissan ce. It is characterized by the combination of injection profiles, the directions and angles of projections of which lead to straight, pale sectors forming thrust surfaces with integral recovery of power.

La figure 1 représente vu en élévation et en coupe longitudinale la turbine dans son ensemble
La figure 2 est une coupe transversale du même ob- jet.In the accompanying drawings given by way of non-limiting example or forms of embodiment of the object of the invention
Figure 1 shows in elevation and in longitudinal section the turbine as a whole
Figure 2 is a cross section of the same object.
Le stator de la turbine 1, îg d et 2, est consti- tue par un carter circulaire 1 avec orifice d'admission 2 assurant le passage intégral du fluide moteur dans la chambre circulaire de repartition 3. La couronne doinjee- tion concentrique est formée par une série d'orifices injecteurs périphériques orientes 4, 5, dont les secteurs 6, 7 ont des profils déflecteurs 8, 9 etc.. délimitant le diamètre et le sens directionnel des injecteurs. The stator of the turbine 1, fig d and 2, is constituted by a circular casing 1 with an inlet orifice 2 ensuring the complete passage of the working fluid in the circular distribution chamber 3. The concentric crown is formed by a series of oriented peripheral injector orifices 4, 5, the sectors 6, 7 of which have deflector profiles 8, 9, etc., delimiting the diameter and the direction of the injectors.
Les pâles 10, Il et autres de la turbine constitu ant le rotor, sont formées parun secteur rectiligne 12 se prolongeant par une surface plane extérne réceptrice de poussée légèrement coudée 13 suivant une obliquité permettant de recevoir perpendiculairement la veine motrice avec son intensité maximale directe. The blades 10, 11 and others of the turbine constituting the rotor, are formed by a rectilinear sector 12 extending by a planar external surface receiving the slightly bent thrust 13 at an obliquity making it possible to receive the motor vein perpendicularly with its maximum direct intensity.
Cette poussée s'effectue sous un angle minimum de 1000 a et maximum de 1600 b. This thrust takes place at a minimum angle of 1000 a and maximum of 1600 b.
Les profils internes de cette pAle présentent un secteur semi-circulaire 14 se prclongeant par une surface rectiligne 15 radiale assurant l'évacuation du fluide moteur 16. The internal profiles of this blade have a semi-circular sector 14 extending through a rectilinear radial surface 15 ensuring the evacuation of the working fluid 16.
L'angle manimum de projection est de 1000 a et sa- ximum de 160 b. The maximum projection angle is 1000 a and the maximum is 160 b.
C'est donc la combinaison de l'angle d'injection 8, 9, par lequel les profils déflecteurs projettent le fluide moteur sur les profils recepteurs rectilignes 12, 13 de poussée des pales que se caractérise l'invention. It is therefore the combination of the injection angle 8, 9, by which the deflector profiles project the working fluid onto the rectilinear receptor profiles 12, 13 for thrust of the blades that the invention is characterized.
Les forces d'impact, surchaque aube transmettent sans turbulence ni freinage, l'intégralité de la puissance reçue, alors que les profils internes des pâles avec secteurs curviligne 14 et rectiligne 15, accèlèrent le fluide vers l'évacuation 16. The impact forces, on each dawn transmit without turbulence or braking, all of the power received, while the internal profiles of the blades with curvilinear 14 and rectilinear sectors 15, accelerate the fluid towards the evacuation 16.
On supprime ainsi les inconvénients des pâles curvilignes, les turbulences et freinages qu'on rencontre généralement dans les turbines dont les pales présentent à la poussée du fluide, une surface curviligne. This eliminates the drawbacks of curvilinear blades, the turbulence and braking that is generally encountered in turbines whose blades have a curvilinear surface at the thrust of the fluid.
Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, as indeed the materials used for their manufacture, without thereby changing the general conception of the invention which has just been described.
