Description

1 2496780

  The present invention relates to the field of

  valves and flow nozzles and concerns, in

  In addition, nozzles of fluid flow by means of which one seeks to obtain a particular jet whose direction changes automatically without interruption. The nozzles of

  flow rate are used, particularly in hydro-

  therapy and are able to charge for this purpose a mixture

turbulent air and water.

  Fluid valves and flow rate nozzles of known type include devices having hand-adjustable outlets as described in United States Patent Application No. 4,221,336 issued September 9, 1980. However, the

  Applicant knows no valves or nozzles allow-

  so much to create a directional fluid outflow whose

  the direction changes automatically without interruption.

  As far as he is aware, the known nozzles used in hydrotherapy massage, produce a directionally adjustable outlet jet whose orientation is static unless it is modified by hand. On the contrary, the novel valve of the invention described below has the main purpose of producing a jet of water and air which continuously produces a conical or annular surface of revolution or variants of this surface. The invention also aims to ensure the flow of the air mixture and

of intimate water.

  The fluid valve according to the invention is, therefore, able to exert a therapeutic massage effect on a much wider surface and is superior to the statically oriented jet of known embodiments. The invention relates to a valve for delivering a directional output fluid jet whose direction changes continuously, automatically and in a recurring and reproducible pattern. The valve relates, in particular, to fluid flow nozzles used in

  hydrotherapy, in which air is intimately mixed

  flow (liquid) to create a directional flow of air and turbulent water

direction changes continuously.

  The valve according to the invention comprises a main valve body comprising a first fluid inlet means, a first fluid outlet means and a valve bore, preferably in the cylindrical assembly, which is interposed between the first means of entry and the

  first fluid outlet means and which is in communication with

  with them. A cylindrical barrel or a chamber of

  hollow rotor is mounted in the main valve body.

  The cylindrical rotor chamber is provided with a wall

  end of a central opening on the intake side

  sion or upstream side of the valve. This rotor chamber has a diameter smaller than that of the bore of the valve and is mounted coaxially so that the cylindrical wall

  the chamber is spaced from the wall surface

  of the valve bore. The cylindrical wall of the rotor chamber contains one or more openings

  radially outer parts which serve as

  fluid flow. The rotor chamber is preferably movable along the longitudinal axis of the bore of the valve to various multiple positions. In an extreme position of these multiple positions, the central opening of the end wall of the rotor chamber, on the intake side or upstream side, is closed by a plug centered in the inlet side of the bore of the valve

  and, in the opposite extreme position, the admission opening

  the central wall in the end wall of the rotor chamber is fully open. Intermediate positions between these extreme positions, cause various degrees of closure or closure of the central inlet opening of the rotor chamber. Fluid present in a flow of fluid entering the bore of the valve from the first fluid inlet means is thereby divided, during its movement, between the central inlet opening of the fluid chamber. rotor and the radially outer intake ports of a

  predetermined manner easily adjustable.

  A long tubular rotor body is mounted in the rotor chamber, the rotor body having a rotor bore passing therethrough. The rotor body is mounted in the rotor chamber to be rotated or oscillated and rotated about the longitudinal axis of the bore of the valve. type of mounting depending on the location of the rotor bore in the rotor body. In operation, the rotor chamber is positioned in the bore of the valve and along the longitudinal axis thereof in a predetermined manner, by means of an adjustment knob operable from the inside or from the outside. Fluid flow is

  primed and the fluid is divided between the intake opening

  central portion of the rotor chamber and the radially outer intake ports of this rotor chamber, in a preset proportion depending on the axial adjustment of the rotor chamber. The fluid passing through the radially outer fluid inlet ports of the rotor chamber exerts a force on the outer surface of the wall of the rotor body and initiates the rotational movement and tilting (oscillation) movement of the body. rotor, or a purely rotary movement, depending on the type of assembly provided for the body of

  rotor. So, if the rotor bore is positioned coaxially

  in the rotor body, the rotor body is mounted

  in order to be able to be animated by a movement of

  lation and rotation. The fluid pressure exerted tangentially on the outer wall of the body of the

  rotor with the fluid from the intake lights

  radially outward movement, then causes an oscillation and uninterrupted rotation of the rotor body and initiates a recurrent angular displacement and

  of the rotor bore relative to the longitudinal axis

  tudinal of the valve bore. The outgoing fluid has the shape of a directional jet whose direction changes without

  interruption between predetermined fixed limits

  undermined by the amplitude of the oscillation movement of the rotor body. When the rotor body is mounted to be driven in a pure rotational movement in the rotor chamber, the radially outer fluid inlet ports in the rotary chamber are positioned

  to direct the flow of tangential inlet fluid

  ture on the wall surface of the rotor body in a continuous manner and rotate it. In this case, the rotor bore is wholly or partially eccentric with respect to the longitudinal axis of the valve bore or is parallel to this longitudinal but radially offset axis thereof. Fluid flow

  resulting from a flow through the exchangeable rotor bore

  The continuously rotating jig is a directional fluid jet whose direction changes continuously, extending over a conical surface of revolution while the directional fluid jet exiting the bore

  radially offset but parallel which turns without interruption

  ruption, has the form of an annular water flow.

  The speed of the streams or jets of direct fluid

  outgoing payments can easily be

  reducing or reducing the flow of fluid passing through the radial outer intake ports. Adjustment may be effected by actuators that can be actuated from the outside or, in some other way, by the

  internal adjustment of the position of the rotor chamber.

  The outgoing fluid stream can, in addition, be mixed with air to form a mixture of air and intimate and turbulent water for use in "whirlpool" hydrotherapy baths. The fluid valve according to the invention is simple to manufacture and safe operation. It requires only a small number of pieces, namely the body of

  valve, the cylindrical rotor chamber longitudinally

  mounted in this body and the tubular rotor body

  mounted so as to rotate or oscillate in the

rotor chamber.

  The fluid valve according to the invention is generally designated by reference numeral 10 and comprises, in general, a long valve body 12, a rotor chamber 50 mounted coaxially in the valve body 12, and a rotor body 80 mounted in the

rotor chamber 50.

  The valve body 12 is provided with a first fluid inlet means 16 having a transverse bore 15 adapted to be sealingly connected to a fluid inlet line (water) shown in dashed lines at 17. fluid bore 15 of the first fluid admission means 16 opens in a section of

  intermediate valve body 19 in the cylinder assembly

  which defines a long cylindrical valve bore 18 having a longitudinal axis X-X. The valve body 12 is provided with a fluid outlet means 22 having a relatively counterbored bore 24 near its mouth or outlet end 25, this bore 24 tapering to a smaller diameter bore 26 which

  immediately downstream of the international section

  mediator 19 of the valve body. The fluid outlet means 22 is provided with air intake means or bore 28 in the transverse assembly, which opens into the bore 26 of the fluid outlet means 22 and allows the air to mix with the outgoing water flow, as explained below in detail. The connection of the tube

7 2496780

  air intake to the bore 28 is illustrated in phantom

interrupted in 30.

  The rotor chamber is mounted to move longitudinally along the longitudinal axis X-X of the valve bore 18. Its mode of travel

  longitudinal axis will be briefly described below.

  As shown in Figs. 1, 3, 3a and 4, in particular, the rotor body or rotor chamber 50 is generally cylindrical and has an end wall 51 at its inlet or upstream end. As clearly shown in FIG. 4, the inlet end wall 51 of the chamber 50 is pierced with a flared central opening or valve seat 53 and the cylindrical wall 52 of the rotor chamber 50 is provided with fluid inlet ports

radially outer, 54, 54a.

  A rotor body 80 is contained, so as to oscillate and rotate, in the rotor chamber 50 in the following manner. The rotor body 80, in the embodiment shown in Figs. 1, 3, 3a and 4, is a long tubular element having a rotor bore 81 which passes through it coaxially from one side to the other. The tubular wall 83 of the rotor body 80 is enlarged near one of its ends to form a toric mounting means or member 82, which protrudes from the surface of the wall of the tubular rotor body 83 and which is off-center by relative to the length of the rotor body. The toric element 82 is mounted so as to be able to oscillate from one

  limited angle and can be rotated in the cylindrical bore

  drique 55 of the cap 56, the cap being, in turn, pressed into the open upstream end of the rotor chamber 50. As clearly shown in FIGS. 1 and 4, the downstream end 85 of the rotor body 80 passes through the cap 56, the rotor body 80 being however retained (so as not to move axially downstream) in the cap 56 by its annular shoulder 58 which extends radially inwards. The cap 56 is, in turn, stably held in the downstream end of the rotor chamber 50 by means of a retaining member

  screwed 56a (see in particular Fig. 4).

  The rotor chamber 50, with the rotor body 80 assembled therein, as shown in FIG. 4, is then fixed or mounted in the following manner on a knob or adjustment member 100 in the frustoconical assembly. The adjustment knob 100 is provided with a threaded connection end 102 which has a threaded surface

  103 and a threaded surface 104 as clearly shown by

  Figs. 1 and 2. The retaining member 56a of the rotor chamber 50 has a part of its outer wall 52 which is threaded, as indicated by the numeral 63, the threaded surface 63 being screwed into the complementary threaded surface 103 of the connecting end 102 of the adjustment knob. Adjustment knob 100 and rotor chamber 50 are now equivalent, in a functional sense, to a single element of a workpiece. The flared adjustment knob 100 and the rotor chamber 50 attached thereto are now introduced into the valve body 12 and rotated until the threaded surface 104 is fully screwed into the threaded surface 110 of the bore. valve 18, as shown in FIG. 1. In this state shown in FIG. 1, the central inlet opening or valve seat 53 of the rotor chamber 50

  is completely closed by a truncated stopper

  112 which is fixed in the valve bore 18 and on the axis thereof by means of a cross-member 113. The cross-piece 113 and the plug 112 are preferably in one piece with

the valve body 12.

  The adjustment knob 100 has protruding wings 117 which can easily be

  grasp and rotate it in the valve body 12.

  The flared body 120 of the adjusting knob 100 has a plurality of longitudinal slots 122, as shown in FIGS. 1 and 2, the purpose of which is to allow manual compression of the mouth 124 of the adjustment knob 100, so that an annular widening

9 2496780

  or an annular retaining bead 126, formed on the outer surface of the body 120 of the adjusting knob, can move inwardly beyond a shoulder of

  retainer 128 formed on the valve body 12 just in the

  25. The annular retaining bead prevents accidental axial movement of the adjustment knob 100 relative to the body of the mouthpiece.

valve 12.

  In the assembled state shown in FIG. 1, the adjustment knob 100 can be rotated counterclockwise to disengage the central aperture 53 forming the valve seat from the stopper.

  shutter 112 (this position is not shown).

  Fluid entering the fluid intake means 16 can therefore (or not) pass through the central opening 53

  forming a valve seat of the rotor chamber 50.

  It should also be noted that the outer cylindrical wall 52 of the rotor chamber is spaced from the inner wall surface of the valve bore 18 so that fluid does not pass through the central valve seat opening 53. flows through radially outer inlet ports 54, 54a of the rotor chamber 50 and into the chamber of

rotor itself.

  With regard to detail the function-

  of the fluid valve of FIGS. 1 to 4 and the analysis of the state shown in FIG. 1, all the water that enters the fluid inlet bore 15 from

  the pipe 17 passes through radiant intake ports

  54, 54a (since the shutter plug 112 has closed the central inlet opening 53 forming valve seat). The intake ports 54, 54a are inclined to inject fluid onto the walls of the rotor body 80, with a substantially tangential force component relative to the wall of the rotor body, to impart a high degree of rotation. the rotor body counterclockwise, as illustrated by way of example in FIG. 3a,

  or in a clockwise direction.

  As mentioned above, the upstream side 85a of the rotor body 80 is heavier than the downstream side 85 since the fulcrum provided by the O-ring 82 and the bore 55 of the bonnet 56 is off-center. The rotor body thus initially occupies an inclined non-axial position in which the downstream side 85a is located lower than the upstream side 85, as shown in FIG. 1. As the water pressure continues to be applied, either of the fluid jets from tangential inlets 54 or 54a spreads the inlet or upstream side 85a of the rotor body from its initial position and brings him into the path of

  the other tangential entry of fluid jets. This move

  This cement is repeated in one direction and the other between the tangential fluid jets, causing the upstream side 85a of the rotor body 80 to tilt diametrically across the rotor chamber 50, so that the upstream side is either constantly solicited in a sense deviating from '

  the longitudinal axis of the rotor chamber 50.

  The net result is that the input or upstream side a of the rotor body 80 tends to describe a surface of revolution in the conical assembly whose vertex is at the point of support formed by the toric surface 82. It is clear that the downstream or outlet side 85 of the rotor body describes a similar but opposite path around the toric point 82. Thus, as the rotor body 80

  moves under the influence of the angular injected fluid

  The rotor bore 81 is angularly displaced without interruption relative to the longitudinal axis of the cylindrical valve bore 12 and the fluid entering the rotor chamber 50 then enters the moving rotor bore 81. and is projected by it through the valve 10 in the form of a directional jet whose direction changes continuously. Various patterns of movement of the rotor body 80 can be obtained by changing the angle at which the tangential entrances

  54 and 54a open into the rotor chamber 80.

  When the valve seat opening 53 of the chamber 50 is opened to allow increased central flow through the interior of the chamber, the fluid flow impinging on the wall of the rotor body 80 decreases and therefore the rate of exit flow and / or conical surface of revolution produced by the jet

directional decrease.

  Air is introduced, if desired, into the directional output fluid jets exiting the downstream or outlet side 85 of the rotor bore 80. This introduction is effected by aligning the openings 140 provided for in FIG. the air entering through the openings 140 at the throat of the venturi formed in the flared adjustment knob 100 is intimately mixed with the flow of the throttle adjustment knob 100, with the air intake means. directional fluid projected towards

  outside and constantly changing direction. The the-

  truncated cone of the venturi of the regulating member 100 is

designated by reference 142.

  The valve 10 as a whole, as shown in FIG. 1, is attached to a suitable wall, for example to a swirl bath tub wall 146 and at this

  Indeed, it is introduced into a wide opening.

  the wall is secured to the wall by means of a threaded ring 148 shown in broken lines and mounted on the threaded surface 31 of the body

valve 12.

  The elements of the valve are preferably made of metal or plastic. The valve body 12 is preferably made of brass while the adjusting knob 100, the rotor chamber 50, the rotor body 80 and the cap 56 are preferably made of a tough plastic material.

  low coefficient of friction as Lexan 141 manufactures

  General Electric Company. Of course, other materials may be used for the purposes

of the present invention.

  In the embodiment of Figs. 1 to 4, the rotor body 80 is rotatably and rotatably mounted in the rotor chamber 50. The same rotor chamber 50 is also used with a modified form of rotor body 180, this rotor body 180 being mounted in the rotor chamber 50 to substantially simply rotate therein under the influence of the fluid which enters the interior of the rotor chamber 50 through the fluid intake ports 54, 54a, as the show

clearly Figs. 5-6a.

  In the variant shown in Figs. 5 to 6a, the rotor body 180 is generally of a cylindrical nature and comprises an upstream portion 184 and a downstream portion 182 separated by a transverse annular ring 183. The downstream portion 182 of the rotor body 180 passes through the bore longitudinal 187 hat 185 and can turn in it. The ring 183 serves as a retaining member preventing axial displacement of the rotor body 180 towards

downstream.

  The cap 185, which carries the rotor body 180 in the manner described above, is then pressed into the open downstream end 57 of the rotor chamber 50, as shown in FIG. 6, and is stably retained by the threaded retaining member 185a. The upstream portion 184 of the rotor body is thus completely contained in the rotor chamber 50 and is mounted therein essentially to rotate only about the longitudinal axis of the rotor chamber 50 and about the longitudinal axis. XX of the valve bore 18 when the rotor chamber 50 is mounted in the valve bore 12,

as shown in FIG. 1.

  The outer wall of the upstream portion 184 of the rotor body 180 is provided with a plurality of protruding longitudinal ribs 193. As clearly shown

  FIG. 6a, the fluid entering the admission lights

  radially outward inclined pressure 54, 54a enters the annular space 194 provided between the rotor body

13 2496780

  184 and the inner wall 52a of the rotor body 50 and thus exerts a pressure in the opposite direction to that of the needles of the watch on the ribs 193. The rotation of the rotor body 180 in the direction indicated is then initiated. The fluid then flows from the annular passage 194 to the upstream or inlet end 196 of the rotor bore 198 and flows downstream into the rotating rotor bore. The rotor bore is eccentric, at least at its downstream or outlet side; the eccentric bore (designated 198a) describes a conical surface of revolution when the rotor body 180 is rotated, and the fluid stream leaving it follows an effluent path whose

  direction constantly changes following a path of revolu-

conic version.

  Since the rotor chamber 50 and the cap 185 are essentially of the same configuration as in FIG. 1, the means for dividing or adjusting the flow of fluid between the valve seat central opening 53 and the radially outer apertures 54, 54a and thereby controlling the speed of the directional fluid jet exiting the bore of rotor 180, the external adjustment means and the means for mixing air and water are essentially the same as those described with reference

in FIG. 1.

  Another embodiment of the invention is

  shown in Figs. 7 and 8. In this form of

  According to the invention, the rotor body 200 comprises, as in FIGS. 5 to 6a, an upstream portion 202 and a downstream portion separated by a transverse ring 206. The upstream portion 202 is provided with projecting vanes 207. The body of

  rotor 200 is mounted so as to be essential

  This is a pure rotational movement, as described with reference to the rotor body 180 of FIGS. 5-6a. The bore 210 of the rotor body 200, however, is not eccentric but is parallel to the longitudinal axis XX of the valve bore 18 and is radially offset therefrom. The effluent path of the fluid exiting the bore 210 is

14 2496780

  that of a flow whose direction changes constantly and

  which forms an annular surface of revolution.

  Fig. 9 illustrates another variant of the invention

  wherein the rotor chamber 250 and the exterior adjustment knob 260 are cast or molded in one piece. The rotor body 802 is mounted to oscillate and rotate in the rotor chamber 250 by means of a

  O-plug 82 in a manner similar to that shown in FIG.

  felt in Figs. 1 to 4. The upstream end 252 of the rotor chamber 250 is then closed by a plug 254 pierced with a central opening, since the rotor body 80 'must first be introduced into the rotor chamber 250,

by the upstream end 252.

  The rotor chamber 250 and the one-piece adjusting knob 250, together with the rotor body 80 ', are screwed into the valve body 212, the screwed surfaces in one another being generally indicated. by references 270 in FIG. 9. In FIG. 9, the adjustment knob 260 is shown in its extreme downstream position in which the adjustment opening 255 of the wall 257 is completely open so that little fluid, if no fluid at all, enters the chamber

  rotor 250 by radially outer lights 254.

  As you turn the rewind button 260

  to a position further upstream, the central opening 255 is increasingly closed off. Flow adjustment mode

  fluid passing through the central inlet opening 255 and the radially external inlet openings 254 is therefore essentially the same.

  that described above with reference to FIGS. 1 to 4.

  The valve body 300, as shown in FIG. 11, is essentially of the same configuration as that shown in FIG. 1 and is used as a valve body for other types of valves as well, such as

illustrated in the drawings.

  The valve body 300 has a bore or fluid inlet means 297, a closure plug

The valve body 300, as described, is designed to contain not only the elements of the valve according to the invention, but also the inner elements of a hand-adjustable directional jet of the type described in US Pat. No. 4,221,336. A spring 302, inner and outer bushings 304, 306, and a hand-turnable ball valve 308 are contained in the counterbored downstream valve bore 311, and a fluid flow choke 315 is threaded. on the threaded surface 305 just upstream of the air intake means 309 to create a mixture of air and intimate water as the water exits the choke 315 and enters the downstream counter section. reamed 311 of the valve bore. The configuration of the valve body according to the invention

  therefore presents multiple applications.

  Of course, the invention is in no way limited to the described details of execution to which changes and modifications can be made

without leaving his frame.
