Abstract

A nozzle discharging a stream of continuously changing direction, particularly for use in hydrotherapy to discharge a turbulent jet of an intimate water-air admixture, produces a (preferably adjustable) discharge pattern covering a conical or annular surface of revolution, or variations thereof. The nozzle comprises a body (12), a rotor chamber (50) coaxially within the body, and a rotor body (80) within the chamber. Water is fed to inlet (16) and enters the chamber (50) through tangential inlets (54) to pass through the bore (81) of the rotor body, causing it to rotate, and discharged through a flared mouth (25). A control knob (100) can be rotated to influence the fluid flows and the motion of the rotor body by moving aperture (53) away from plug (112) so that the water enters the chamber (50) axially. Air may be introduced, downstream of the rotor body (80), through inlet (28). <IMAGE>

Description

SPECIFICATION A fluid valve with directional outlet jet of continuously changing direction The invention lies in the field of fluid valves and discharge nozzles and more particularly pertains to fluid discharge nozzles wherein a particular discharge pattern, having an automatic continuously changing direction, is desired. The fluid discharge nozzles have particular application in hydrotherapy and are adapted to discharge a turbulent air-water admixture for this purpose.

Fluid valves and discharge nozzles of the prior art include units having manually directionally adjustable outlets such as is disclosed in applicant's Patent No. 4,221,336 entitled "NOZZLE WITH DIRECTION ALLY VARIABLE OUTLET", issued on September 9, 1980. However, applicant is not aware of any valves or nozzles for creating a directional outlet jet of fluid of automatically continuously changing direction.

Prior nozzles used in hydrotherapy massage, of which I am aware, have a directionally adjustable outlet jet which is directionally static unless manually altered. By contrast, it is a major object of the novel valve disclosed herein to produce a discharge jet of water and air which continuously generates a conical or annular surface of revolution or variations thereof. It is a further object to produce a discharge oftlie intimate admixture of air and water.

The fluid valve of this invention is therefore capable of therapeutic massaging action over a much wider surface area, and would be superior to the directionally static jets of the prior art.

This invention is directed towards a fluid valve for discharging a directional outlet fluid jet of continuously changing direction, automatically, and in a repetitive, reproducible pattern. The fluid valve pertains, in particular, to fluid discharge nozzles for use in hydrotherapy, wherein air is intimately admixed with the effluent liquid (water) stream, to create a turbulent air-water directional outlet stream of continuously changing direction.

According to the present invention there is provided a fluid valve for discharging a directional outlet fluid stream of continuously changing direction, comprising a first fluid inlet means, a valve body having an inlet portion communicating with said fluid inlet means and having a valve bore therethrough, said valve bore having a longitudinal axis and a fluid outlet means, an elongated rotor body mounted within said valve bore and having a rotor bore passing therethrough, said rotor body being mounted for movement within said valve bore to enable displacement of said rotor bore with respect to said longitudinal axis of said valve bore, said rotor bore having a rotor bore inlet and rotor bore outlet, said rotor bore outlet communicating with said fluid outlet means of said valve body; and a rotor chamber surrounding said rotor bore inlet and having a fluid inlet port means in communication with said first fluid inlet means, said fluid inlet port means of said rotor chamber being radially offset with respect to said longitudinal axis of said valve bore, and said fluid inlet port means of said rotor chamber being in communication with said rotor bore inlet whereby fluid entering said first fluid inlet initially passes into said radially offset fluid inlet port means of said rotor chamber and thence exerts external force on said rotor body to cause movement of said rotor body and displacement of said rotor bore with respect to said longitudinal axis of said valve bore, the fluid passing through said rotor bore inlet and thence through said rotor bore outlet as a directional outlet stream of predetermined continuously changing direction, as determined by the displacement of said rotor bore.

The valve of this invention comprises a main valve body having a first fluid inlet means, a first fluid outlet means, and a preferably, generally cylindrical valve bore interposed between, and in communication with, the first fluid inlet and outlet means.

Mounted within the said main valve body is a cylindrical housing or hollow rotor chamber. The cylindrical rotor chamber is provided with a centrally apertured end wall on the inlet or upstream side of the valve. This rotor chamber is of smaller diameter than the valve bore diameter and is mounted coaxially therewith whereby the cylindrical wall of the chamber is spaced from the valve bore inner wall surface. The cylindrical wall of the rotor chamber contains one or more radially outer apertures which function as fluid inlet port means. The rotor chamber is preferably movable along the longitudinal axis of the valve bore to a number of multiple, different, positions.In one extreme of such multiple positions, the central aperture of the end wall of the rotor chamber, on the inlet or upstream side, is closed by a plug, centrally mounted in the inlet side of the valve bore and in the opposed extreme position, the central inlet aperture in the rotor chamber end wall is completely open. Intermediate position, between these extremes, cause various degrees of closure of the central inlet aperture of the rotor chamber. In this way, fluid in a fluid stream entering the valve bore from the first fluid inlet means is divided, in its travel, between the central inlet aperture of the rotor chamber and the radially outer inlet ports, in a predetermined, readily adjustable, manner.

An elongated tubular, rotor body is mounted within the rotor chamber, the rotor body having a rotor bore extending therethrough. The rotor body is mounted, within the rotor chamber, for either rotational motion or rotational rocking movement, about the longitudinal axis of the valve bore, the type of mounting depending upon the location of the rotor bore within the rotor body.

in operation, the rotor chamber is positioned within, and along the longitudinal axis of the valve bore in a predetermined manner, by means of either an internally or externally operable control knob.

Fluid flow is initiated, and the fluid is divided between the central inlet aperture of the rotor chamber and the radially outer inlet ports of the rotor chamber in a preset proportion depending upon the axial setting of the rotor chamber. The fluid passing through the radially outer fluid inlet ports of the rotor chamber exerts force on the rotor body wall exterior and initiates both rotatory and up-down (rocking) movement of the rotor body, or purely rotational movement, depending upon the type of mounting provided for the rotor body. Thus, if the rotor bore is coaxially positioned within the rotor body, the rotor body is mounted for both rocking and rotational movement.Fluid pressure exerted, tangentially, on the exterior wall of the rotor body by means of fluid flow from the radially outer inlet ports, will then cause continuous rocking and rotational motion of the rotor body and initiates continuous, repetitive, angular displacement of the rotor bore with respect to the longitudinal axis of the valve bore. The effluent fluid will exit in the form of a directional jet of continuously changing direction extending between fixed preset limits dictated by the extent of the rocking movement of the rotor body.

When the rotor body is mounted, for pure rotary movement, within the rotor chamber, the radially outer fluid inlet ports in said rotary chamber are positioned so as to direct the inlet fluid stream, tangentially, onto the rotor body wall surface, in a continuous manner, and cause rotation thereof. In this case, the rotor bore will be either wholly or partially eccentric with respect to the longitudinal axis of the valve bore, or will be parallel but radially offset with respect to said longitudinal axis. The flow of fluid, resulting from flow through the continuously rotating eccentric rotor bore is a directional fluid jet of continuously changing direction extending over a conical surface of revolution while the directional fluid jet exiting from the continuously rotating radially offset but parallel bore, takes the form of an annular stream of water.

The velocity of the exiting directional streams or jets of fluid is readily adjustable by increasing or decreasing the fluid flow flow through the radial outer inlet ports. Adjustment maybe made by externally operable control members or by otherwise internally adjusting the rotor chamber position.

The effluent fluid stream may be further admixed, with air, to form an intimate, turbulent, air-water admixture for use in hydrotherapy "whirlpool" baths.

The fluid valve of this invention is simple to make and reliable in operation. It requires only a small number of parts, i.e., the valve body, the longitudinally adjustable cylindrical rotor chamber mounted therewithin, and the tubular rotor body mounted for movement, either rotary or rocking, within the rotor chamber.

The fluid valve of this invention is designated generally by the numeral 10 and comprises, generally, an elongated valve body 12, a rotor chamber 50 coaxially mounted within the valve body 12, and a rotor body 80 mounted within the rotor chamber 50.

The valve body 12 is provided with a first fluid inlet means 16 having a transversely aligned fluid bore 15 adapted to be sealingly connected to a fluid (water) inlet pipe denoted in phantom line 17. The fluid bore 15 offirstfluid inlet means 16 opens into a generally cylindrical intermediate valve body section 19 defining an elongated 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 enlarged bore 24 adjacent the mouth or exit and 25 thereof; the bore 24 stepping down to a smaller diameter bore 26 which bore 26 is located immediately downstream of intermediate valve body section 19.The fluid outlet means 22 is provided with a generally transversely extending air inlet means, bore 28, opening into bore 26 of the fluid outlet means 22, which bore 28 enables air admixture with the effluent water stream to take place as will be explained hereafter in detail. The air inlet tube connection to bore 28 is shown in phantom line 30.

Mounted for longitudinal movement, along the longitudinal axis X-X of valve bore 18, is the rotor chamber. The manner of its longitudinal axial movement will be described shortly hereafter.

Referring now to Figures 1,3, 3a, and 4, in particular, the rotor housing or chamber 50 is generally cylindrical in shape and is provided with an end wall 51 at the inlet or upstream side of chamber 50. As best shown in Figure 4, the inlet end wall 51 of chamber 50 is provided with a flared central aperture or valve seat 53 and the cylindrical wall 52 of rotor chamber 50 is provided with radially outer fluid inlet ports 54, 54a.

A rotor body member 80 is contained, for rocking and rotational movement, within the rotor chamber 50 in the following manner. The rotor body member 80, in the embodiment shown in Figures 1,3, 3a and 4 is an elongated tubular member having a rotor bore 81 extending coaxially therethrough. The tubu lar wall 83 of rotor body 80 is enlarged near one end thereof forming a toroidally-shaped mounting means or member 82, projecting from the surface of the tubular rotor body wall 83 in an off-center relationship with respect to the length of the rotor body. The toroidal ly-shaped member 82 is seated for both limited up-down (rocking) movement and rotational movement within cylindrical bore 55 of cap member 56, the cap member, in turn, being pressfitted into the open, upstream, end of the rotor chamber 50.As clearly shown in Figures 1 and 4, the downstream end 85 of rotor body 80 extends through cap member 56, the rotor body 80 being, however, retained (from axial downstream displacement) within cap member 56 by its radially inwardly extending annular shoulder 58. The cap member 56, in turn, is stably held within the downstream end of rotor chamber 50 by means such as a threaded retaining member 56a (see Figure 4 especially).

The rotor chamber 50, together with the rotor body 80 assembled therein, as shown in Figure 4 is then affixed or mounted to a generally frustroconical adjustment, or control, knob or member 100 as follows. The control knob 100 is provided with a threaded connector end 102, the connector end having both an internally threaded surface 103 and an externally threaded surface 104 as best seen in Figures 1 and 2. The retaining member 56a of rotor chamber 50 has a portion of its external wall 52 thereof threaded, as designated by the numeral 63, the threaded surface 63 being threadably mounted to complementary threaded surface 103 of the control knob connector end 102. The control knob 100, and the rotor chamber 50 are now equivalent, in a functional sense, to a single, unitary, component.

The flared control knob 100 and rotor chamber 50, affixed thereto, are now inserted into the valve body 12 and rotated until threaded surface 104 is completely threadably engaged to the internally threaded surface 110 of valve bore 18, as shown in Figure 1. In this condition, as shown in Figure 1, the centrally located inlet aperture, or valve seat 53 of rotor chamber 50 is completely closed by a tapered valve plug 112 secured within, and along the axis of, the valve bore 18, by means of a transversely extending strut member 113. The strut 113 and plug 112 are preferably integrally formed with the valve body 12.

The control knob 100 has protruding wing portions 117 to enable easy gripping thereof and easy rotation within valve body 12.

The flared body 120 of control knob 100 is provided with a plurality of longitudinally extending slots 122, as shown in Figures 1 and 2, the purpose of which are to enable manual compression of the mouth 124 of control knob 100 thereby enabling an annular enlargement or annular retaining bead 126, formed on the exterior of the control knob body 120, to move inwardly past an annular retaining shoulder 128 formed on valve body 12 just inwardly of the mouth 25. The annular retaining bead prevents accidental displacement, in an axial direction, of the control knob 100 relative to the valve body 12.

In the assembled condition, shown in Figure 1, the control knob 100 is rotatable in a counter-clockwise direction to unseat the central valve seat aperture 53 from the valve plug 112 (this position not being shown). Thus, some fluid, entering the fluid inlet means 16 may (or may not) pass through central valve seat aperture 53 of rotor chamber 50.

It is also to be noted that the outer cylindrical wall 52 of the rotor chamber is spaced from the inner wall surface of the valve bore 18 whereby fluid not passing through central valve seat aperture 53 will pass through radially outer inlet ports 54, 54a of rotor chamber 50 and thence into the rotor chamber interior itself.

To further expand on the operation of the fluid valve of Figures 1 - 4, and analyzing the condition shown in Figure 1, all of the water entering the fluid inlet bore 15 from pipe 17 will pass through radially outer inlet ports 54, 54a (since valve seat 112 has closed off the central inlet valve seat aperture 53).

The inlet ports 54, 54a are inclined so as to inject fluid onto the walls of the rotor body 80, with a substantial tangential component of force, relative to the rotor body wall, to thereby impart a high degree of rotation of the rotor body in either the counterclockwise direction, as shown in Figure 3a, by way of example, or in the clockwise direction.

As mentioned previously, the upstream side 85a of rotor body 80 is heavier than the downstream side 85 because the fulcrum provided, bytoroidal seat 82 and the bore 55 of cap member 56, if off-center. The rotor body will thus initially assume an inclined non-axial attitude wherein the downstream side 85a is below the upstream side 85, as shown in Figure 1.

As the water pressure continues to be applied, one or the other of the fluid jets from tangential inlets 54 or 54a will displace the inlet side 85a of rotor body 80 away from its initial attitude and into the path of the other tangential inlet of the fluid jets. This displacement repeats itself back and forth between the tangential fluid jets causing the inlet side 85a of the rotor body 80 to toggle diametrically across the rotor chamber 50, such that the inlet side 85a is constantly being urged away from the longitudinal axis of the rotor chamber 50.

The net result is that inlet side 85a of rotor body 80 will tend to describe a generally conical surface of revolution with its apex at the fulcrum provided by toroidal surface 82. It is clear that the outlet side 85 of rotor body 80 describes a similar but opposite trajectory about toroidal fulcrum 82. Thus, as the rotor body 80 moves under the influence of angularly injected fluid the rotor bore 81 will be continuously angularly displaced with respect to the longitudinal axis of the cylindrical valve bore 12; and fluid entering the rotor chamber 50 then enters, and is projected by, the moving rotor bore 81 through the valve 10 as a directional jet of continuously changing direction. Various patterns of movement of the rotor body 80 may be obtained by changing the angle at which the tangential inlets 54 and 54a enter the rotor chamber 80.

As the valve seat aperture 53 of chamber 50 is opened to permit more flow centrally through the chamber interior, there is less fluid flow impinging on the wall of the rotor body 80 and consequently the velocity of the outlet stream and/or the conical surface of revolution generated by the directional jet will decrease.

Air is introduced, if desired, to the directional outlet fluid jets, exiting from the outlet side 85 of rotor bore 80. This is accomplished by aligning openings 140, formed at the throat control knob 100, with the air inlet means 28. Air entering the openings 140 at the throat of the venturi formed within the flared control knob member 100 will be intimately admixed with the onrushing, exiting, continuously changing directional fluid stream. The frusto-conical bore of the vents tri of control member 100 is designated by the numeral 142.

The entire valve assembly 10, as shown in Figure 1 is attached to an appropriate wall, such as a whirlpool bath wall 146 by inserting the valve 10, through an appropriately sized opening in the wall, and securing the valve 10 to the wall by means of threaded collar 148 shown in phantom, mounted to the externally threaded surface 31 of valve body 12.

The valve components are preferably made of either metal or plastic. The valve body 12 is preferably made of brass; whereas the control knob 100, rotor chamber 50, rotor body 80, and cap member 56 are preferably made of low-friction tough plastic such as Lexan 141, manufactured by General Electric Company. It will be understood that other materials may be employed to fulfill the purposes of this invention.

In the Figure 1 - 4 embodiment, the rotor body 80 is mounted for both rotational and up-down rocking motion within rotor chamber 50. The same rotor chamber 50 is also employed with a modified form of rotor body 180, this rotor body 180 being mounted within rotor chamber 50 for substantially rotational motion only, under the influence of fluid entering the interior of rotor chamber 50 through fluid inlet ports 54, 54a, as best shown in Figures 5 - 6a.

In the modification shown in Figures 5 - 6a the rotor body 180 is generally cylindrical in nature and comprises an upstream portion 184 and a downstream portion 182 separated by a transversely extending annular collar 183. The downstream portion 182 of rotor body 180 extends through, and is rotatable within, longitudinally extending bore 187 of cap member 185. Collar 183 acts as a retaining member preventing axial displacement of rotor body 180 in the downstream direction.

Cap member 185, carrying the rotor body 180 in the manner aforedescribed, is then press-fitted into the open, downstream end 57 of rotor chamber 50, as shown in Figure 6, and further stably retained by threaded retainer member 185a. The upstream portion 184 of rotor body is thus wholly contained within rotor chamber 50 and is mounted therewithin for essentially rotational movement only about the longitudinal axis of the rotor chamber 50 and about the longitudinal axis X-X of valve bore 18 when rotor chamber 50 is mounted within valve bore 12 as shown in Figure 1.

The exterior wall of upstream portion 184 of rotor body 180 is provided with a plurality of upstanding, longitudinally extending, flange members 193. As best shown in Figure 6a, fluid entering inclined radially outer inlet ports 54, 54a enters the annular space 194 between the rotor body 184 and the interior wall 52a of rotor body 50, and thereby exerts pressure in a counter-clockwise direction, on the flange members 193. Rotation of the rotor body 180 in the direction shown, is then initiated. The fluid then proceeds, from the annulus 194 to the upstream or inlet end 196 of rotor bore 198 and downstream through the rotating rotor bore.The rotor bore is eccentric, at least at its downstream or outlet side; the eccentric bore (being designated by the numeral 198a) will, when rotor body 180 is rotated, describe a conical surface or revolution, and the fluid stream exiting therefrom, will follow an effluent path of continuously changing direction along a conical path of revolution.

Inasmuch as the rotor chamber 50 and cap member 185 is essentially of the same configuration as in Figure 1, the means for dividing or adjusting fluid flow between central valve seat aperture 53 and radially outer ports 54, 54a and thereby regulating the velocity of the directional fluid jet emanating from rotor bore 180, the means of external control, and the means of air-water admixing are essentially the same as described with reference to Figure 1.

Another embodiment of my invention is shown in Figures 7 and 8. In this embodiment, the rotor body 200 has, as in Figures 5 - 6a, an upstream portion 202 and a downstream portion 204 separated by a transversely extending collar member 206. The upstream portion 202 is provided with upstanding paddle members 207. The rotor body 200 is mounted for essentially pure rotational motion, in the manner described with reference to rotor body 180 of Figures 5 - 6a. The bore 210 of rotor body 200 however is not eccentric but is parallel to and radially offset from, the longitudinal axis X-X of valve bore 18. The effluent path of fluid flow from bore 210 traces a continuously changing directional stream forming an annular surface of revolution.

Figure 9 depicts a further modified embodiment of my invention wherein the rotor chamber 250 and external control knob 260 components are cast or molded as an integral unit. The rotor body 80' is mounted, for rocking and rotational motion, within the rotor chamber 250, by means of torodial plug 82, in a manner similar to that shown in Figures 1 - 4.

The rotor chamber 250 then has its upstream end 252 closed off by centrally apertured plug 254 since the rotor body 80' must be first inserted, within the rotor chamber 250, through the upstream end 252.

The unitary rotor chamber 250 and control knob 260, together with the rotor body 80' is threadably mounted into valve body 212, the engaging threadable surfaces being indicated generally by the numerals 270, in Figure 9. In Figure 9, the control knob 260 is shown in its most downstream position wherein the control aperture 255 of plug 257 is completely open - so that little, if any fluid flow will enter the rotor chamber 250 through radially outer ports 254. As the control knob 260 is rotated to a more upstream position, the central aperture 255 is closed off to a greater and greater degree. The manner of adjustment of fluid flow through the central inlet aperture 255 and the radially outer inlet ports 254, is thus essentially the same as that heretofore described with reference to Figures 1 - 4.

The valve body 300, as shown in Figure 11, is essentially of the same configuration as that shown in Figure 1, and is utilized as a valve body for other types of valves as well, as will be shown.

The valve body 300 has a fluid inlet bore or means 297, a centrally located, integral valve plug 301 in the inlet or upstream side, a generally cylindrical valve bore 303 immediately downstream of plug 301, a transverse air inlet bore or means 309 communicating with the valve bore just downstream of the threaded surface area 305, and an enlarged valve bore 311 at the downstream end of the valve body 300. The valve body 300, as described, is designed to contain not only the components of the valve of the instant invention, but is designed so as to contain the internal components of a manually adjustable directional jet stream, of the type described in my Patent No. 4,221,336. Thus, a spring member 302, inner and outer bearing members 304, 306 and manually rotatable discharge ball or nozzle 308 is contained within enlarged downstream valve bore 311, and afluidflow restrictor 315 isthreadably mounted to threaded surface 305 just upstream of the air inlet means 309 in order to create an intimate air-water admixture as the water exits from the restrictor 315 and enters the enlarged downstream bore section 311. The valve body configuration of this invention thus can be seen to have multiple uses.

It will be appreciated by those skilled in the art that many changes, modifications and substitutions are possible without departing from the spirit and scope of this invention. Therefore, applicant intends to be bound only by the scope of the appended claims.
