Description

Nutant fluid supply device.

Background of the invention

Shower heads, faucets and other heads or atomizing nozzles, are commercially available According to numerous designs and configurations. While many shower taps and heads are designed and sold for your decorative installation, there are a large number of mechanisms of different shower heads that have been planned to improve or change some characteristic of the water atomization pattern. Any particular atomization pattern can be described by The characteristics of atomization width, distribution or atomization path, atomization speed, and Similar. In addition, the atomization pattern may be adapted to, or designed for various purposes, including a more sensation pleasant skin, better rinsing behavior, muscle massage and water conservation, just to name a few.

The vast majority of atomization heads they can be classified as stationary or oscillating, and have openings or suppliers both fixed and adjustable. Heads Stationary atomization with fixed suppliers, are the most simple atomization heads, consisting essentially in a water chamber and one or more dispensers directed so that They produce a constant configuration. Atomization heads stationary with adjustable suppliers are typically of similar construction, except that some adjustment of the spout address, spout opening size, and / or number of suppliers used. For example, a shower head typically used in the construction of new homes residential, provides atomization housing stationary that has a plurality of atomization jets arranged in a circular pattern, in which the speed of atomization is adjustable by manually rotating a ring of adjustment in relation to the atomization housing.

These stationary atomization heads they make water flow through their openings and go through essentially the same trajectory repetitively, such as a shower head that directs the water spout to a position fixed on the skin of a person. The user of that head of shower experiences a stream of water continuously on it  area and, in particular, at high pressures or flow rates, the user can feel that the water is piercing his body, thereby reducing the positive effect derived from that head shower In order to reduce this undesirable feeling of shower heads, and to improve water distribution from the atomization heads in general, various attempts to provide oscillating spray heads.

Examples of oscillating shower heads are described in US Pat. Nos. 3,791,584 (Drew et al .), 3,880,357 (Balsch), 4,018,385 (Bruno), 4,944,457 (Brewer), and 5,577,664 (Heitzman). US Patent No. 4,944,457 (Brewer) describes an oscillating shower head, which uses a driving wheel mounted on a gearbox assembly that produces an oscillating movement of the nozzle. Similarly, US Patent No. 5,577,664 (Heitzman) describes a shower head having a rotary valve member actuated by a wheel, and a gear reducer to cyclically regulate the flow rate through the housing between high and low flow rates. Both shower heads mentioned require extremely complex mechanical structures in order to perform the desired movement. Consequently, these mechanisms are prone to fail due to the wear of the various pieces and to mineral deposits throughout the structure.

US Patent No. 3,691,584 (Drew et al .) Also describes an oscillating shower head, but uses a nozzle mounted on a rod that rotates and pivots under forces acting on it by virtue of water entering through radially arranged grooves, towards a camera around the stem. Although this shower head is simpler than those of Brewer and Heitzman, it still includes a large number of parts that require precise dimensions, and numerous connections between parts. In addition, the shower head is based on small openings for water passages, and is subject to mineral deposition and particle binding.

U.S. Patent no. 5,467,927 (Lee) describes a shower head with a device that has a plurality of Blades designed to produce vibration and pulsation. A shovel has endowed with an eccentric weight that causes vibration, and a shovel opposite has a front flange that causes pulsation by momentary blocking of water jets. Again, The construction of this shower head is quite complex and its narrow passages are subject to mineral deposition and binding with particles

US Patent No. 5,704,547 (Golan et al .), Describes a shower head that includes a housing, a turbine and a fluid outlet body, whose circulation of said fluid through the turbine causes the turbine to rotate. The rotary (rotary) turbine can be used to cause rotation of the fluid outlet body and / or an oscillating movement from side to side, in a manner similar to a pendulum.

U.S. Patent no. 4,073,438 (Meyer) describes a spray nozzle that has a housing with an inlet, a water distribution structure that has a nozzle in a end, and a cup-shaped element at the opposite end that It is operational in response to the tangential flow of water to the housing, to effect the orbital movement of the nozzle. It also describes a disc that rotates in rolling contact with a surface inside the housing, to carry out the fractional rotation of the nozzle. The cup-shaped element rotates around the longitudinal axis in response to the tangential flow of water from the entrance.

With reference to Figure 35, U.S. Patent no. 3,091,400 (Aubert) describes a dishwashing machine that has a rotating oscillating atomizer apparatus, comprising a body of atomization that has an atomization head and a piece of bearing, along with a ring that surrounds it. The apparatus 10 of oscillating atomization comprises body part 12, which has a atomization head 14 attached thereto, and a ring 16 which go around The body part 12 has a bearing seat 18 internal conical, and is located in a water supply conduit 20 which has a rounded edge that forms a bearing seat 22. The extended piece 12 has a collar 24 pushed down over the supply line 20, and an adjacent step 26, which is  projects outwards, hooks with the bottom side of the ring 16 and it rolls on it when water is supplied under pressure. Water supplied through conduit 20 enters in a distribution chamber 28 and emerges through the openings atomization 30 of the atomization head 14. The orientation of the openings 10 is chosen so that a moment of a set of moments puts the atomization body in rotation, bringing the step 26 of body 12 rolls over ring 16 as has been indicated in point 32.

A main advantage of the Aubert document is that the oscillation movement is caused by the tangential orientation of the atomization head openings, thereby limiting the choice of atomization patterns. Specifically, the tangential openings will form a pattern of very wide atomization that can be useful for dishwashers, but that It is very unwanted for a shower head. In addition, due to the mass of the atomization head 14 and the annular contact between the step 26 and ring 16, the water supply must be developed at high speed and pressure with internality to the head of Atomization start to oscillate.

U.S. Patents no. 2,639,191 and 3,357,643 (both from Hruby) describe a sprinkler and a source device, that have an elongated tubular rod received by a bushing in the inside of the elongated tubular body, in which the bushing provides sufficient clearance for the rod to allow the stem to rotate or swing inside a body elongated tubular However, this device is also based in a tangential flow of fluid to drive the rod. Further, the stem and body are so long that the device would not be Suitable for many applications.

U.S. Patent no. 3,009,648 (Halt) describes a spray head that has a single piece nozzle fixed to a fluid conduit, in which the nozzle has a conical plug inverter supported in position by means of struts. Stopper includes a plurality of openings to induce a rotating movement  of the nozzle. The sprayer distributes water according to a current swivel

U.S. Patents no. 5,439,174 and 5,588,595 (Sweet), as well as U.S. Patent no. 5,671,885 (Davisson), describe nutation sprinklers that have a portion body with a nozzle at one end and an atomizer plate supported on it at the opposite end downstream of the nozzle. The atomizer plate has a plurality of grooves current distributors, formed on one side of it, configured so that the atomizer plate rotates when it is hit by a current emitted from the nozzle. The atomizer plate has an axis coupled to the body by means of a ball and cage, a bearing cage or a flexible connector, respectively. The fluid is directed against the atomizer plate and deviates radially out of the atomizer plate without no control or redirection of fluid.

However, there is still a need for a perfected atomization head, shower head or other discharge apparatus that supplies a fluid, such as water, from a uniform and controlled way. It would be desirable for the head of atomization were trained to supply water the way desired, even at low pressures or adequate flow rates For use in shower heads and sump taps. The device should preferably cause a minimum pressure drop and supply fluid according to a directional atomization pattern. It would also be desirable for the atomization head to provide a Simple and compact design that includes a minimum of parts.

Detailed description of the invention I. Atomizer Head Assemblies that Include a Camera

The present invention provides a set of atomizer head with a mobile atomizer nozzle that supplies fluid according to an atomization distribution substantially uniform. The atomizer nozzle movement it is an oscillating movement, preferably combined with some rotational movement The oscillating movement is generated arranging an oscillating inductor member or oscillating turbine in the fluid supply path, inside a accommodation. The flow of water on the oscillating turbine causes that oscillates the oscillating turbine, in which the axis of the turbine rotates or it swings around a reference axis defined by the (the) swing limiter member (s). Turbine oscillating then causes the atomizing nozzle to oscillate. He atomization pattern produced by the atomizing nozzle oscillating changes more or less quickly so that the drops or the  fluid streams are directed along paths arched over time, instead of continuously on a single point This type of atomization distribution pattern is softer than many stationary patterns, and the unique design of The oscillating turbine does not include complex mechanical parts or significant flow restrictions.

More in particular, the present invention provides an atomization head assembly that has a housing, a nozzle assembly, a swing inducing member and a swing limiter. The accommodation has a first end that has a fluid inlet, and a second end that form a collar or opening in it. Nozzle assembly it has a first end that forms a pole arranged inside of the housing, a middle portion that extends through the opening, a second end that has a fluid outlet, a fluid conduit that provides fluid communication between the housing and fluid outlet, and limiter limiter of oscillation. The nozzle assembly is located downstream of fluid inlet The oscillation inducing member is arranged in the fluid channel that faces the inlet of fluid, and has a sleeve that extends from it to Loosely receive the post on it. The set of nozzle is oscillated with the passage of fluid flow, on or to through the oscillation inducing member.

The post comprises at least one entry, with preference a plurality of radial channels, and a step that provides fluid communication between the post inlet and the fluid outlet The input can be tangential to the line center of the passage. The pole and sleeve can be tapered.

Preferably, the fluid outlet comprises an atomizing nozzle and a plurality of outlet channels formed in the spray nozzle. An item can be arranged sealing between the collar and the middle portion of the set of nozzle, to prevent fluid leakage out of the housing to through the collar.

In another embodiment, the present invention provides an atomizer head assembly that has a housing, a nozzle that has a limiter member of swing, and a swing inducing member. Accommodation it has a first end that has a fluid inlet and a second end that forms an opening. Nozzle assembly it has a first end that forms a sleeve arranged in the inside the housing, a middle portion that extends to through the opening, a second end that has an outlet of fluid, a fluid conduit in fluid communication between the housing and fluid outlet. The first end of the set of nozzle is positioned downstream of the inlet of fluid. The oscillation inducing member is arranged in the accommodation that faces the entrance, and that has a post that extends from it in relation to loose coupling with the sleeve, preferably the post and sleeve conical

In another embodiment, a set is provided atomizer head that has a housing, a nozzle that It has a swing limiter member, and a member swing inductor The accommodation has a first end that it has a fluid inlet end, a second end that it has an opening, and a flow channel that extends between the First and second extremes. The nozzle assembly has a first end arranged inside the housing, the member swing inductor coupled to the first end, a portion half extending through the opening, the limiter member oscillation, such as an oscillating plate, coupled to the portion half adjacent to the opening, a second end that has a outlet nozzle, and a water channel that provides communication of fluid between the flow channel and the outlet nozzle.

Preferably, the inducing member of swing is a swinging turbine head, and the head of oscillating turbine forms a conical surface with grooves partially tangential that face the entry end of housing fluid. In a preferred embodiment, the member swing inductor can be a swinging turbine head which has a plurality of spans that extend radially, positioned downstream of the fluid inlet of accommodation. The oscillating limiter member may be a ring subject to spans.

An aspect of the present invention provides an atomizer head assembly with an inductor member of swing or a swinging turbine that makes the turbine atomizer oscillate regardless of quantity, design or configuration of the atomizer nozzle outlet channels. More particularly, the oscillation inducing member is not based in tangential exit channels made in the nozzle atomizer This allows nozzle outlets atomizer are designed in such a way that they produce a pattern and a desired atomization width, such as for a shower of one living place.

Another aspect of the invention provides a atomizer nozzle that can include any number and configuration of output channels, but preferably has a reduced number of output channels that have larger dimensions internal to prevent jamming due to mineral deposits  or to an accumulation of particles. Since the nozzle atomizer is oscillating, fluid distribution or coverage On a surface it is extremely uniform. Therefore, it they need less output channels to provide coverage complete a surface and, in case of a shower, get a feeling of softness Since a smaller number of channels, each channel can be widened so that it is less the channels are likely to be narrowed or plugged with the lime, or with other minerals or particles. More preferably, the channels are wide enough for sand to pass ordinary introduced into the fluid feed.

In addition, the invention provides a system of speed at which an important portion of the pressure drop, and preferably substantially all the pressure drop, to through the atomizer head, it is produced in a large hole that create a water dispenser that is guided and distributed down by  The open channels. This speed system is advantageous for reduce the mineral deposition and weight of the atomizer head and of the spray nozzle. There is less mineral formation using a speed system because the output channels are not longer depending on the openings having small areas in cross section to divide the flow of water into streams individual and therefore the output channels can be widened or re-designed. Head weight atomizer and atomizer nozzle decreases with a system of speed, because the spray nozzle is running below the flow restriction hole and therefore is not filled with liquid during operation. On the contrary, the atomizer nozzle includes a housing and a diverter in the inside the housing to direct the water that leaves the orifice. The reduced weight is particularly beneficial in a oscillating spray nozzle because the reduced mass causes a proportional reduction in the angular momentum of the atomizing nozzle that causes head housing vibration atomizer. While the speed system, as just describe and as supported by the following Figures, it is preferably using in combination with the members oscillation inductors described here, being able to speed also be used together with other mechanisms oscillators, including that of U.S. Pat. no. 5,551,635, whose Patent is incorporated herein by reference, and that of U.S. Pat. no. 4,073,438, whose patent is also incorporated herein as reference.

Still another aspect of the invention provides a limiter of oscillation. The atomization width of a atomizing nozzle of the present invention, is determined both for the design of the outlet channels in the nozzle atomizer as per the angle of deflection imparted in the nozzle  atomizer For example, if the spray nozzle provides a 6º atomization width during use in a stationary mode, and the oscillation produces an angular deflection of 5º out of the center, then the effective atomization width during use in oscillating mode according to the present invention will be of around 16º (additional width of 5º in all directions). Therefore, the swing limiter member plays a role important in determining the effective atomization width of the atomizing nozzle, as well as the extension of the arc path that each fluid stream crosses during A simple swing.

A further aspect of the invention consists in a swing inducing member that is arranged in relation to direct contact or engagement with the head assembly atomization. While the oscillation inducing member can be coupled, attached or otherwise fixed to a set of spray nozzle, it is generally preferred not to integrate or fix the swing inductor member with the nozzle assembly atomizer More particularly, the atomizer nozzle assembly It has an end that is distal in the spray nozzle. Be prefer that this distal end of the nozzle assembly atomizer and oscillation inducing member each receive at another in relation to loose male-female, particularly where the distal end and the limb can easily slide or pivot in proper relationship without limitation. A particularly preferred arrangement consists of a post cylindrical (male) received inside a cylindrical sleeve  (female), where the external diameter of the post is smaller than the inner diameter of the sleeve. Alternatively, the post can form a truncated conical surface (male) received inside of a truncated conical cuff (female), where the truncated conical angle of the post is less than the conical angle of the sleeve. Be You must understand that the post can be part of the nozzle assembly atomizer, and that the sleeve can be part of the inductor member of oscillation, or vice versa. It is preferred to design the post and the sleeve with sufficient tolerances between the two so that the oscillation inducing member may oscillate in relation to the atomizer nozzle assembly without linkage. Also I know prefer more the use of a swing inducing member having a conical or truncated cone with a first diameter, received in a conical or frustoconical cuff of the set of atomizer nozzle

An advantage of the loose relationship, such as a pole and sleeve ratio, of the oscillation inducing member or oscillating turbine, with respect to the body, is that there is very little friction or other forces to be overcome before the oscillating turbine starts to oscillate. In this way, the initiation and maintenance of the oscillating movement of the present invention is substantially independent of speed of fluid flow, and operates very effectively in heads of shower and faucets even at much lower flow rates of 19.46 liters per minute (2.5 gallons per minute) maximum, imposed by the laws of many states.

A second advantage of the post relationship and sleeve is that the oscillating turbine is easily lifted, moved or tilted out of the center line axial fluid inlet. In fact, even when you are not by passing fluid through the atomizer head assembly, the oscillating turbine can remain positioned at an angle inclined relative to the axial center line of the inlet of fluid. In order to provide the oscillating movement more effective, it is preferred that the oscillating turbine be displaced sufficiently out of the axial center line of the inlet of fluid so that an important portion of the fluid supplied through the fluid inlet be directed on one side only from the oscillating turbine face to any given point in the weather. The loose coupling ratio of pole and sleeve, allows the fluid discharge apparatus of the present invention get a sufficient displacement of the turbine oscillating within a much shorter longitudinal distance (the distance measured along the axial centerline from the fluid inlet to fluid outlet), with fewer parts.

Yet another aspect of the invention provides that one or more intermediate sleeves are arranged with a pole and a sleeve as described above. For a set of atomizing nozzle that has a pole, a sleeve and one or more intermediate sleeves, it is preferred that the relationship between each member (post, sleeve and intermediate sleeve) provide swing between them.

Another aspect of the invention provides a channel sufficiently open flow through the head assembly atomizer, so that the speed limitation restriction fluid flow can be a flow control washer arranged in the atomizer head assembly in the vicinity of the fluid inlet, and the hole size just upstream of the nozzle outlet channels atomizer In this way, adequate pressure is maintained in the inside the housing to drive the oscillating turbine, while generating adequate water velocity at the fluid outlet  as to provide a satisfactory shower.

Still another aspect of the invention provides an atomization head assembly that has bolts mounted on the outlet channels of the spray nozzle. The movement oscillating and the forces of the atomizing nozzle, make the bolts rotate or vibrate in contact with the inner surface of the channels, thus eliminating any possibility of mineral formation. The bolts preferably have a head attached to the atomizer nozzle and a shaft attached to the head of the bolt that extends through the output channels. It is important that the head and bolt shaft do not block fluid flow through of the output channel.

It should be appreciated that the atomization heads of the present invention, and the individual components of the themselves, they can be made with any known materials that are resistant to chemical and thermal attack by the fluid that It passes through them. When the fluid is water, the Preferred materials include plastics, such as polytetrafluoroethylene, and metals or metal alloys, such as stainless steel Other additional materials suitable for your use in the present invention, will be apparent to the subject matter experts, and are considered to be within reach of the present invention.

The housing 42 forms a chamber 43 substantially water tight, with an inlet 45 located upstream of the oscillating turbine 44. The ground 50 of the housing 42 forms a collar, hole or opening 52 therethrough, to slidably receive an axis 54 that is fixed to the plate oscillating 46 inside the housing 42, and to the nozzle atomizer 48 outside housing 42. Shaft 54 is sealed inside the hole 52 by means of a sealing lip 56 to prevent water leaks from the housing, while allowing  that the shaft 54 bends and rotates inside the opening 52. An O-ring can also be used to seal the shaft 54 in The opening.

The oscillating turbine 44 has a surface upper 58 conical forming a plurality of non-radial channels 60 (see also Figure 4), and a cylindrical sleeve 62 in general. The upper surface 58 of the oscillating turbine 44 is preferably extends beyond sleeve 62 to form a annular projection 64 facing the lower end 62. The sleeve 62 of the oscillating turbine has an inner surface 68 that defines an inside diameter that is larger than the diameter outside of shaft 54. When assembled, sleeve 62 slides on the shaft or post 54 and the oscillating turbine 44 remains in the upper part of shaft 54.

The oscillating plate 46 has a surface bottom 72 which is tapered upwards out of the ground 50 of housing 42. The angle formed between the oscillating plate 46 and the 50 floor determines the maximum degree of oscillation experienced by atomizing nozzle 48 limiting the inclination of the spray nozzle assembly. Preferably, the surface bottom 72 of the oscillating plate forms an angle between around 1 and around 20 degrees with the 50th floor of the housing 42, more preferably between about 2 and around 10 degrees, and more preferably around 4 degrees, when the center line of the nozzle assembly is aligned with the center line of the accommodation. Tip inclination atomizer will be similarly limited, resulting in the angle mentioned above between the plate and the housing a Increase the effective atomization width of the atomizer head by a factor of twice the angle, that is, the same increase angular in all directions.

The shaft or pose 54 provides a step 74 in fluid communication with shaft input (s) 76 and the atomizing nozzle 48. Inlet 76 consists of preference in a plurality of channels that extend through from the wall of the pole, preferably forming a downward angle from the top of the housing 12 towards the floor of the accommodation. Step 74 comprises a speed tube 75 that limits the flow rate of the fluid through the head atomizer according to water conservation standards, such as at 19.46 liters per minute (2.5 gallons per minute, GPM). Step 74 then opens in fluid communication with the channels outlet 78 of the spray nozzle 48.

Therefore, the fluid follows a path to enter chamber 43 through entrance 45, passing over the oscillating turbine 44, entering through entrance 76 in step 74 of axis 54, and leaving the atomizing nozzle 48 through a plurality of atomization channels 78 in communication of fluid with step 74 of axis 54. In operation, a source of fluid under pressure is in communication with the inlet of the accommodation. The turbine oscillates due to the fluid that impacts on the upper surface of the oscillating turbine. The swing essentially means that the oscillating turbine is inclined to a side and other, and orbit around the central axis of the axis so that the inner surface near the lower end of the turbine oscillating is rolling in contact with the outer surface of the axis. The oscillating action of the oscillating turbine exerts forces on the axis that are transferred to the oscillating plate through the axis, so that the bottom surface of the oscillating plate is in rolling contact with the floor of the housing. Nozzle atomizer also oscillates in response to the oscillating movement of the axis. Once the chamber has been substantially filled with water, water enters here through the shaft inlet and flows through a passage of the shaft to the spray nozzle.

Figure 4 is a cross-sectional view. of the atomizer head 40 taken along the lines 4-4 of Figure 1. The upper surface 58 of the oscillating turbine 44 has been illustrated with grooves 60 formed following a non-radial configuration. It should be appreciated that the fluid flow that impacts on oscillating turbine 44, will push to the oscillating turbine 44 laterally towards an inclined position so that the center point of the oscillating turbine 44 is substantially out of the fluid stream from the input 45, and only one side of the oscillating turbine 44 is aligned with the fluid stream at any point in time. Every one of the channels or slots 60 that have formed at the end upper 58 of the oscillating turbine 44, are non-radial, and act like spans that cause the oscillating turbine to orbit around of the fluid inlet as the fluid circulates through the slots The non-radial grooves 60, the conical surface 58 and the loose relationship between sleeve 62 and post 54, ensure that when the fluid circulates against the top of the turbine oscillating 44 under pressure, oscillating turbine 44 will tilt out from the center, and it will start to swing. More particularly, the fluid that hits the conical surface 58 of the turbine 44, causes a tilting force 31, and the fluid that passes through the grooves 60 causes rotational forces 33. Therefore, the fluid stream that passes through inlet 45, makes swing to oscillating turbine 44 in the direction of the needles of the clock, as shown by arrow 61. Once you have started the oscillating movement, the continuous flow of water keeps oscillating turbine 44 in oscillating mode. In addition, the fluid flow also causes a maintenance force in situation that pushes the turbine down, tending to keep the turbine free to be displaced from its cooperating relationship with the nozzle set Therefore, it is preferred that the angle of the conical surface 58 is large enough to produce at least a slight tilting force even when the turbine is already fully inclined, but not so big as to cause the turbine to go up and out of its contact with the nozzle assembly.

For a given oscillating turbine, the speed or swing ratio can be increased (or reduced) increasing (or reducing) the proportion of fluid flow to through the atomizer head. However, it is possible to design the oscillating turbine so that it has a more oscillation speed fast or slower for a given fluid flow rate changing the angle or pitch of the slots in the oscillating turbine. With reference to Figure 12, an oscillating turbine can be designed so that it has a swing speed generally lower by reducing the pitch of the slots, that is, designing the slots 162 with a small angle, β, relative to the radius. From similarly, the oscillating turbine can be designed so that have a higher swing speed by increasing the pitch of the slots, that is, designing the slots 164 with an angle major, δ, with respect to the radius. Referring again to Figure 4, the slots can even be designed with an angle variable to form a type pattern "wheel-of-peaks". In addition, the number and size of the slots can also be modified to that suits a swing speed.

Figures 17A-I are diagrams schematics illustrating the oscillating movement between a sleeve 62 of oscillating turbine, and a post 54 of nozzle assembly, of according to the atomizer head of Figure 1. Starting with the turbine sleeve 62 and post 54 tilted to the right of housing 42, turbine sleeve 62 and post 54 orbit in favor of clockwise around center point 69 of the accommodation, illustrated here at 45 degree increments between figures. Since post 54 and sleeve 62 always tilts in the same direction, their respective central points 71, 73 are substantially radially aligned with the point central 69 of the accommodation. According to orbit the turbine sleeve 62 clockwise (as shown by the movement of the central point 71 of the turbine, around the center point 69 of the housing), sleeve 62 forces the post 54 to lean and orbit in the same direction of the needles of the clock (as shown by the movement of the center point of the pole around center point 69 of the housing).

Making brief reference to the Figure 1, turbine 44 and turbine sleeve 62 contact the post 54 at three points: (1) the lower inner edge of the sleeve 62 in the direction of inclination (i.e. right in Figure 1); (2) an inner point near the upper end of the sleeve 62 in the outward direction of the inclination (it is say, on the left in Figure 2), and (3) the underside of the turbine. Since there are three points of contact, it is necessary that one or more of the points move so that the rock turbine. Although all contact points are wet by the fluid, such as water, the continued use of the turbine can cause some marginal wear on the pole or surface cuff inside.

Figures 10A-I are diagrams schematics illustrating the oscillating movement between a plate swing and floor of the housing of the present invention. Due to the angle formed between the oscillating plate and the ground, a rolling contact circle between the oscillating plate and the ground defines a first circle on the oscillating plate 46 that has a diameter 47 (and a circumference) that is different from diameter 51 of a second circle on the floor 50 of the housing 42. With the In order to maintain contact with the ground, the oscillating plate must absorb the difference of the circumferences by rotation. As shown, if the diameter of circle 47 is smaller than the diameter of circle 51, then (in the absence of slippage between the oscillating plate and the floor), the oscillating plate 46 will rotate (as indicated by arrow 140) in a direction opposite to the oscillation (as indicated by arrow 142). Each view Next of Figures 104A-I represents a 45 degree swing in favor of clockwise.

The oscillation begins in Figure 10A with the pole (not shown) tilted towards the bottom of the page, so that the first circle 47 of the oscillating plate is pushed to contact circle 51 of floor 50. For the purpose illustrative, two triangular markers 144, 146 have been placed on the oscillating plate 46 and on the floor 50, respectively, adjacent to the initial point of contact between circles 47, 51. As the oscillation, and consequently the point of contact, is moves in favor of the clockwise, the oscillating plate You experience a slight rotation against the hands of the clock. For the diameters 47, 51 given, shown in the Figures 10A-I, it seems that during a full swing, the oscillating plate 46 rotates about a quarter turn in opposite direction, to provide a swing: ratio of rotation of about 4. The rotation in this case occurs in the opposite direction of oscillation because the diameter and the circle circumference 47 are smaller than the diameter and the circle circumference 51 (that is, D_ {3}> D_ {4}). It will also be appreciated that the ground itself could be conical. It will be appreciated that the oscillation ratio: rotation can be increased by providing a greater difference in the diameters of, or of the angles between, the oscillating plate and the ground. The principles that govern the oscillation relationship: rotation that just describe with respect to the oscillating plate and the ground, are also true for the oscillation inducing member or the turbine swing and post.

Referring again to Figure 1, the post 54 is surrounded by two intermediate sleeves 80, 82 (the use of intermediate sleeves is optional), which have a diameter greater than that of axis 54 and less than that of sleeve 62 of the oscillating turbine 44. The sleeves 80, 82 oscillate (i.e. tilt and turn around the axis) when they come in contact with the inner surface 66 of the oscillating turbine 44. The addition of the sleeves allow the oscillating turbine to tilt in a desired angle while maintaining a small contact angle between the surfaces

The pole or shaft 54 also includes a channel of absorption 84 that opens towards an annular cup 86 of the nozzle atomizer 48 in proximity to opening 52. The channel of absorption 84 traps any water that can escape from around of the opening 52, and in case no sealing is used. The vacuum created by the water leaving the exit channels 78, water from cup water 86 through absorption channel 84, and towards step 74. Channels 84 also supply air to the space located below the speed tube 75, allowing with it that the stream of water coming out of the speed tube 75 maintain your speed while being diverted and guided towards down the channels 78.

Figure 2 is a cross-sectional view. of a second embodiment of atomizer head assembly. He atomizer head 90A is substantially the same as the head atomizer 40 of Figure 1, except as regards the ratio between the oscillating inductor member or oscillating turbine 92, and the distal end 94 of the atomizer nozzle assembly. From according to the discussion above, the oscillating turbine 92 includes a post 96, instead of a sleeve, and the distal end 94 Includes a cuff 98, instead of a pole. In addition, post 96 and sleeve 98 illustrates the use of conical surfaces 100 and 102, respectively, which more preferably have a common point pivoting 104 at some point along the center line. As in the case of the oscillating turbine 44 above, the fluid flow from inlet 45 impacts on the surface 58 and tilts oscillating turbine 92 aside until surfaces 100, 102 come into contact. The fluid flow to through slots 60 on one side of the turbine, imparts tangential forces on oscillating turbine 92 (as has been described in relation to Figure 4), causing it to oscillate oscillating turbine inside the sleeve 94. The component of oscillating motion bearing, can be displayed easily in this 90 atomizer head configuration more easily than in the configuration of the atomizer head 40, because  probably to the contact between turbine post 96 and the sleeve 98 is substantially a line instead of the three points of contact shown by turbine 44 of Figure 1.

Figures 18A-I are schematic representations of the oscillating movement between the oscillating turbine post 96 and nozzle assembly sleeve 98, according to the atomizer head of Figure 3. Due to that the diameter of circle 59 formed on the surface of the turbine 96 is smaller than the diameter of circle 61 formed in the opposite surface of sleeve 98, as turbine 96 oscillates clockwise, turbine 96, exemplified by circle 61 will turn in the opposite direction to the needles of the watch. Atomizer head 90A is preferred over head atomizer 40 because the wear associated with three is eliminated contact points. It is estimated that reduced wear is a combined result of eliminating the three contact points and allow the rotation of the nozzle assembly (contrary to the clockwise for a swing in favor of the hands of the clock as shown in Figures 10A-10I), it match the turbine rotation (contrary to the needles of the clock for a swing in favor of clockwise). Due to which the post 96 and sleeve 98 rotate in the same direction, the amount of friction between the two is significantly reduced or Possible is removed. Although the atomizer head 90 has been represented with post 96 and sleeve 98 provided with most preferred frustoconical surfaces, it is also suitable make post 96 and sleeve 98 so that they have simple cylindrical surfaces.

Figure 3B is a cross-sectional view. of the atomizer head of Figure 3A with two details modified. First, the atomizer head 90B incorporates a nozzle assembly having a thin-walled tube 110, which attach the oscillating plate 46 with the atomizing nozzle 48. The tube thin-walled has been made preferably with a material very rigid, preferably a metal such as stainless steel, with in order to reduce the external diameter of the tube 110B (in comparison with tube 110A of Figure 9A). For example, the tube can comprise a stainless steel tube that has a diameter internal of about 3.81 mm (0.15 inches) and a diameter outer of about 4.57 mm (0.18 inches). Reducing the external diameter of tube 110B, the amount of force is reduced required to tilt or tip the nozzle assembly.

Second, the atomizer head 90B has been shown with one or more channels or bypass slots 112, to divert a portion of the fluid around turbine 60. The bypass channels 112 may be desirable to reduce the forces applied to the turbine by water, and consequently reduce the forces applied between the turbine and the set of nozzle, and between the nozzle assembly and the ground, and the like, up to the amount of forces needed to maintain a swing reliably. It is estimated that some forces unnecessarily high could cause increased wear between the mobile members of the atomizer head, and a generation of noise

Figure 5 is a bottom view of the head atomizer that shows the atomizer nozzle outlets. While the output channels can be provided in one way known in the state of the art, a set is defined preferred output channels 78 by a plurality of fins 79 connected to a baffle 77. The primary objective of the baffle 77 is to provide a curved path for water that circulates through the nozzle. It is preferred to direct an amount smaller of the output channels 78 with a smaller angle to the atomizer nozzle shaft 48 in order to provide a more uniform coverage or spray pattern on an object, to a short distance from the atomizer head, such as a person who  take a shower. Preferably, output channels 78a are formed with a smaller angle at separate intervals around the perimeter of the spray nozzle or in radially internal positions towards the central axis of the atomizing nozzle One represented).

Figure 6 is a cross-sectional view. of an atomizer head assembly 120, in which the numbers same point similar elements of the previous embodiment illustrated in Figure 2. The existing input channels 76 in post 54, extend towards step 74 at an angle tangential with the central axis of post 54 and step 74, which causes the fluid to form whirlwind. The whirling fluid or spiral 122, pass through step 74 to the nozzle atomizer 124. Since the moment of the whirling fluid force the fluid out against the walls of step 74 and the spray nozzle 124, no baffle is required. With Preferably, the atomizing nozzle also includes fins 79 for reduce or eliminate the whirlwind of the fluid and define a number of fluid streams coming out of the spray nozzle. Plus preferably, the fins are arranged so that they cause the fluid exits at an angle of 5º with the central axis of the post.

Figure 7 shows a sectional view cross section of an alternative atomizer head 130, constructed and operational in accordance with a preferred embodiment of the present invention, and in which the same numbers indicate elements similar to those of the previous embodiment illustrated in Figure 2. The atomizer head 130 has an atomizer nozzle 132 with bolts 134 located in the output channels 136. Bolts 134 they have a head at one end arranged inside the chamber or step 138 and a straight rod in general that extends descending to, or through, the output channels 136. The centrifugal force generated by the oscillating spray nozzle causes the bolts 134 to rub and maintain the sides of the channels Output 136 free of lime and other mineral deposits. The self-maintenance feature is very useful in areas where water has a high concentration of lime and of other minerals, and a pressure atomizer head is desired.

Figures 8A-D are graphic representations of the uniformity of the patterns of atomization of four atomizer heads, including three commercially available showerheads (Figures 8A-C) and a shower head made according with Figure 2 of the present invention (Figure 8D), at a Atomizer head distance. Figures 9A-D they are similar graphics prepared using the same four shower heads, but at a greater distance. Each of the atomizer heads was connected to a pressure source water constant, and usually directed down on a row of glass tubes, each of which has a diameter about 6.35 mm (1/4 inch). The results of this experiment are shown in the graphs as a side view of the liquid collected in the tubes. It is clear that the results shown in Figures 8D and 9D provide the distribution of more uniform water across the width of the atomization pattern. The other graphs show a tendency to concentrate the water supply in a small point or sub-region of the atomization pattern.

Figures 11A and 11B are side views schematics of the atomizer head 40 according to Figure 2 and the water pattern supplied by the spray nozzle 48. Yes atomizing nozzle 48 would remain stationary, it would result an atomization width defined by dashed lines 150 of according to the design of the spray nozzle itself. When allows the atomizing nozzle 48 to oscillate according to the present invention, the atomization width is increased by 2α, where a is the same angle as the angle between the plate oscillating and ground (see Figure 2). Figure 11 illustrates also the only atomization pattern that can be seen to simple view. The rapid oscillation of the spray nozzle 48 causes the individual currents or drops come off and expand over an arched trajectory For example, suppose the nozzle atomizer has twelve output channels: three output channels 78th directed to 2nd out of center, and nine channels directed to 6th out of center. If the atomizer head It is designed to present a 2º oscillation, that is, provide an angle of 2º between the oscillating plate and the ground, then a total atomization angle of 16 ° will be reached. Market Stall that an oscillation of 2º will provide 4º of deflection (that is, 2nd in all directions), the three output channels directed at 2º they will atomize fluid at angles that cover from 0º to 8º from the axis, which represents a quarter of the atomizer head area, and the nine output channels directed at 6º will atomize fluid by angles covering 8º to 16º, which represents the three quarters of the atomization area. It should be appreciated that they can be used many other designs and arrangements of output channels of according to the present invention.

Figure 13 is a cross-sectional view. of an alternative atomizer head assembly 160, constructed and operational in accordance with a preferred embodiment of the present invention, and in which the same numbers indicate elements similar to those of the previous embodiment illustrated in Figure 2. The atomizer head assembly 160 has a housing 42 for contain an oscillating turbine 44 and an oscillating plate 46. The housing 42 forms a chamber 43 with an input 45 positioned upstream of the oscillating turbine 44. The ground 50 of the housing 42 forms a hole or opening 52 therethrough to slidingly receive an axis 54 that has been fixed to the plate oscillating 46 inside the housing 42, and to the nozzle atomizer (not shown) outside housing 42. Shaft 54 is seals inside hole 52 by means of a lip of sealed 56 to prevent water leakage from the housing while allowing shaft 54 to tilt and rotate inside opening 52. An O-ring can also be used to seal shaft 54 in the opening. It should be appreciated that the opening 52, in all the embodiments described herein, it is sufficiently wide enough to allow the shaft to rotate and pivot around the center line of the housing, so that the swing movement described. While accommodation 42 it is preferably substantially fluid tight, it is expected some fluid passage between shaft 54 and opening 52, and that is  within the scope of the present invention.

The oscillating turbine 44 has a surface 58 conical upper, which has a plurality of spans 164 that they extend radially, and a sleeve 62 generally cylindrical. The openings 165 are preferably tapered downwards and towards the center line of turbine 44, similar to a propeller. The openings 165 and the surface 167 inclined or truncated, act so that they induce the oscillating movement of the oscillating turbine when they come into contact with a stream of water, in a very similar to the slots of the oscillating turbine of Figure 2. With In order to limit the degree of oscillation, a swing limiter element 166, which may be a ring mounted around the perimeter of spans 165 as has represented, or the ends of each span 165 may be formed so that they face upstream as shown in the Figures 15 and 16. The oscillation limiter element 166 acts to limit the degree to which the oscillating turbine leans over the axis, to achieve a result similar to that of the plate oscillating described above. Preferably, the item 166 oscillation limiter forms a truncated conical surface 169 which is inverted with respect to the conical surface 167, so that the defined step between surfaces 167, 169 is pushed to remain in alignment with the fluid entering the housing 42 from dispenser 171, even as the turbine 44. For example, if turbine 44 is in position substantially vertical, then the fluid that passes through the spout 171 will push against surface 167 and cause the turbine 44 bends to one side. However, when turbine 44 bends sufficiently so that the surface 169 of the member 166 oscillation limiter be drawn into the fluid flow passing through the nozzle 171, then the fluid pushes against surface 169. Preferably, surfaces 167, 169 are designed with sufficient angles and surface areas of so that the inclination of the turbine is limited. It should be appreciated also that spans 165 can extend between surfaces 167, 169, either exactly radially (as shown in the Figure 14) or by forming an angle somewhat offset from the radius. The spans that have a greater angle deviated from the radius, may be designed so that they drive the turbine more correctly in a desired orbit without security, or perhaps with some security, about a tracking ring to limit the degree of inclination. In addition, it may be useful to provide grooves or projections on the surface 167 of the tracking ring in order to increase the relative force that is applied to the tracking ring.

The oscillating turbine 44 preferably forms a plurality of openings 168 that are in fluid communication with step 174 of axis 54. Sleeve 62 of the oscillating turbine it has an inner surface 68 that defines an inner diameter that is larger than the outer diameter of the shaft 54. When assembled, the  sleeve 62 slides on shaft 54, and oscillating turbine 44 is keeps on top of the shaft 54. The oscillating turbine 44 and the shaft 54 may be made of TEFLON or other polymeric material suitable, to allow some friction between the oscillating turbine 44 and axis 54, and so that the oscillating turbine 44 can move freely around axis 54. The openings can replace essentially to the oscillating plate, described above, due to to the fact that the ring compensates and controls the amount of oscillation experienced by the shaft and spray nozzle. He oscillating movement is, in this embodiment, the same as described above in Figures 10A-I.

Figure 14 is a top view of the turbine Oscillating 44 shown in Figure 13. The openings 165 are located forming an angle such that when the flow of fluid from the entrance hits the openings, the oscillating turbine will lean to a side and start to rock. The oscillation limiter element 166 of this embodiment, it is a tracking ring. The ring is tapered down, and has an outer diameter that is larger than the external diameter of the upstream water inlet. The ring tracking acts to limit the oscillation movement of the turbine in the same way as in the oscillating plate described previously.

Figures 5 and 16 are section views transversal and from above, respectively, of a sixth embodiment of the present invention, constructed and operative of according to a preferred embodiment of the present invention, and in which the equal numbers indicate elements similar to those of the previous embodiment illustrated in Figure 13. The turbine oscillating 44 has a plurality of tapered spans 165 that cause that the oscillating turbine bends to one side and begins to oscillate by contacting the water coming from the entrance. Taperings of the openings act to limit the oscillation of the turbine oscillating 44. The oscillating movement used by the ring of tracking and / or tapered spans, is the same as described previously in relation to the Figures 10A-I.

Figure 19 is a side view, in section transverse, of a fifth embodiment of a head assembly atomizer of the present invention, and in which the same numbers indicate elements similar to those of the previous embodiment illustrated in Figure 2. The atomizer head 170 includes a lift turbine 172 which has an upper surface 58 with slots 60 as in the other embodiments of the invention that have been discussed previously. The lift turbine 172 it also has a sleeve 174 with fluid passages 176 therethrough, and a swing limiter plate or member 178 attached to the end of the sleeve 174 opposite the turbine surface 58. While that the oscillating plate 178 will oscillate on the floor 50 as it has been described in Figures 10A-I, the oscillating plate 178 is part of turbine 172, instead of the nozzle assembly 180 as in the other embodiments described herein. For him Otherwise, turbine 172 itself will oscillate according to the Figures 10A-I

The oscillating plate 178, or alternatively another cuff portion, includes an annular lifting ring 182, shown here as an inward lip, which is arranged in a constrained position with respect to an annular groove of pairing 184, in a portion of the nozzle assembly 180, such  as the top portion of the post. In this way, the action oscillating of turbine 172, oscillating plate 178 and lip 182, cause lip 182 to go up and down one side of the set of nozzle 180 in an instant by contact with the upper wall 186 of the groove 184, and cause the nozzle assembly 180 to oscillate on the swing limiting surface 183. As the oscillating plate 178, lip 182 will maintain a point of contact with surface 186 of nozzle assembly 180, and plate oscillating 178 will maintain another point of contact with the ground 50, where the two points are on generally opposite sides of the axis 69 atomizer head.

Figure 20 is a side view, in section transverse, of a sixth embodiment of head assembly atomizer, in which equal numbers indicate elements similar to those of the previous embodiment illustrated in Figure 2. The atomizer head 190 includes a turbine 44 which has a upper 58 with grooves 60 as in the other embodiments of the invention discussed previously. Turbine 44 includes also a sleeve 62 which is arranged on a post 54 of a nozzle set Head nozzle assembly atomizer 190 includes an elongated rod 192 having a first end that supports the post, and a second end secured to a atomizing nozzle 194. The atomizing nozzle or housing 194,  it is similar to the nozzle 48 of Figure 2, since the nozzle 194 it includes a baffle 77 and output channels 78. However, the atomizer nozzle 194 also includes a limiter 46 limiter integral oscillation that oscillates on a surface 196 of the accommodation 42. Note that the oscillating movement of the member 46 oscillation limiter on surface 196, is concordant with the description of Figures 10A-I, and the oscillating movement of turbine 44 over post 54 is concordant with the description of Figures 17A-I. An advantage of atomizer head 190 is that the seals 156 can be removed and collar 52 is widened to receive the atomizing nozzle 48. It is preferred that the housing 42 also includes a conduit 194 that directs the flow of fluid around rod 192, and towards its contact with the channels of outlet 78 of the atomizing nozzle 48. More preferably, the defined fluid passage between conduit 194 and nozzle atomizer 48, are aligned so that the fluid passes gently from the duct to the exit channels.

Method and Apparatus for Controlling Fluid Supply

The present invention provides a set of atomizer head that allows the user to adjust or control the less a characteristic of the fluid supplied from the head atomizer, such as the atomization width, the speed of atomization or impact, volumetric flow rate, and the Droplet size The atomizer head assembly includes a housing, a nozzle assembly, an inductor member of movement and a limiter of movement. The types of Useful movements according to the invention include the swing, vibration, spin and the like. The most movement preferred is the oscillation.

The present invention supplies fluid through of a nozzle assembly that is coupled to, or at least in relation to cooperation with, a movement inducing member. Therefore, altering or controlling the movement of the member motion inductor or the nozzle assembly itself, you can achieve alteration or control of the fluid supply from the nozzle set The present invention alters or controls the nozzle assembly movement: (a) either by changing the forces acting on the motion inducing member (it is say, increasing, reducing, redirecting the flow of fluid in relation to the motion inducing member), (b) already is limiting the range of movement that the member can go through motion inductor (i.e. limiting or relaxing the limits physics of the motion inducing member, either directly or either indirectly), (c) either limiting the range of motion that the nozzle assembly can pass through, or (d) either combination of (a) and (b).

The accommodation has a first end that has a fluid inlet, and a second end that forms a collar or opening in it. The nozzle assembly has a first end disposed inside the housing, a middle portion that extends through the opening, a second end that it has a fluid outlet, and a fluid conduit that provides fluid communication between the housing and the fluid outlet. The nozzle assembly is oscillated by fluid flow what has happened, is over, or through the inducing member.

The most preferred atomizer head for use Together with the present invention, it is the oscillating atomizer head described below with reference to the Figures 1-19, whose subject was described herein invention in its U.S. patent application co-pending Series No. 09 / 115,362, deposited on 14  July 1998, whose application is incorporated here as reference. Consequently, the oscillating limiter member comprises an oscillating plate, more preferably a plate oscillating that has a convex conical surface that fits in the housing adjacent to the opening to limit the nozzle assembly movement. In addition, the inducing member of swing is preferably an oscillating turbine, which more preferably it has a convex conical upper surface with angular momentum induction grooves, preferably not grooves radial, formed in it.

The present invention provides a method and a apparatus for altering the fluid supply characteristics of a mobile atomizer head, preferably a nozzle oscillating atomizer. A user can modify the fluid supply characteristics of the spray nozzle manipulating several simple surfaces, including buttons push buttons, buttons with cams attached to them, and others simple devices for manipulation or limitation of atomizer nozzle movement. More in particular, according to described above, the present invention provides fluid through a nozzle assembly that is coupled to, it has formed integrally with, or at least is in relation to cooperation with, a movement inducing member. Thus, altering or controlling the movement of the inducing member of movement, or the movement of the atomizer nozzle itself, is You can alter or control the fluid supply from the nozzle set The present invention alters or controls the nozzle movement: (a) either by changing the forces that they act on the motion inducing member (i.e. increasing, reducing, redirecting fluid flow in relationship with the motion inducing member); (b) either limiting the range of motion through which the motion inducing member (i.e. limiting or relaxing the physical limits of the motion inducing member, either directly or indirectly); (c) limiting the range of movement through which the nozzle assembly can pass, or (d) already either with a combination of (a) to (c).

Figure 21 is a sectional side view cross section of an atomizer head assembly 200 which has a flow washer speed control system. The term "flow washer speed control system", according to used here, refers to atomizer heads that have a flow rate limiting washer 202, arranged downstream of inlet valve 204 and inductor member of movement 92 (i.e. oscillating turbine), but current above the nozzle exit channels 78. The washer 202 flow rate limiter is designed to maintain a relatively constant fluid flow rate through its central hole by constricting the hole as Increase chamber pressure. Additional details and designs of flow rate limiting washers are located described in U.S. Pat. no. 4,457,343 and 4,508,144, the which are incorporated here for reference.

Positioning the washer 202 flow rate, downstream of the inductor member of movement 92, the fluid flow rate that is supplied to through the nozzle 48 is maintained at a given level regardless of fluid pressure or speed in the inside chamber 43. A needle valve 204 is located positioned in a cooperative relationship with a valve seat 206 in order to produce a flow limitation that causes a pressure drop in chamber 43 and an increase in speed of the fluid that impacts the motion inducing member 92. In this way, member 92 (turbine) can be made to move (swing) at high speeds regardless of the pressure of the camera. In addition, at low fluid flow rates, the valve of water may be restricted (i.e. partially closed) in order to maintain a good movement speed u oscillation. It should be noted that at more chamber pressures high, it is necessary to have an effective entry opening more small, to cause sufficient fluid velocity to move member 92 at high speed. For a shower of one housing, the preferred flow washer has a diameter of hole of about 3.25 mm (0.128 inches), and can be used with an outlet tube 208 having a diameter greater than around 3.30 mm (0.135 inches), more preferably around 3.56 mm (0.134 inches).

In accordance with the present invention, an advantage Main flow washer speed control system is that it can be used to control the impact of the fluid coming out of the nozzle. As discussed in what before, when the chamber pressure increases, the hole Flow washer becomes smaller in diameter, which gives as a result a fluid stream of higher velocity than It passes through. In conventional shower heads, the washer flow must be located at the entrance of the chamber, and any benefit of high speed current dissipates in the chamber since the velocity of the fluid leaving the nozzle is determined by the nozzle outlets. In the system of flow washer speed control of the present invention, the output channels of the atomization housing do not restrict the flow of flow, since the joint sectional area Transverse of the channels is much larger than that of the washer flow or speed tube. Consequently, the can fluid speed that passes through the flow washer, enters the atomization housing, is redirected by the deflector, and comes out through the high-speed output channels without any significant restriction. The result is that it can be maintained a constant flow rate while allowing the user to Choose a low impact or high impact atomization.

With the needle valve 204 completely seated (closed), there is no flow through the nozzle. As the needle valve opens slightly, such as turning a handle 210 with a cam 212 attached to the needle valve 204, the fluid passes into chamber 43 at a high speed, causing high oscillation speed and low chamber pressure which causes a soft oscillating atomization. As more opens the needle valve 204, the pressure in chamber 43 is increased, causing the flow washer to restrict and provide a Higher speed atomization and higher impact. Optionally, the motion inducing member can be slowed down or stopped, either by opening valve 204 further to produce a low-speed current, or by opening a detour in around the motion inducing member, to produce a higher uniform impact current. Both atomization Smooth as high impact atomization, provide a flow of fluid according to flow washer class 202.

Figure 22 is a side view, in section transverse, of a head assembly 220 having a valve bypass 222 to redirect fluid around turbine 92, or in around speed tube 75. Bypass valve 222 establishes communication respectively between the fluid inlet and two or more channels chosen between channel 224 directed to the turbine 92, channel 226 directed towards the camera but around the turbine 92, or channel 228 directed around chamber 43 until nozzle assembly 208. Bypass valve 222 is made so that it communicates the fluid coming from the input 45 with one or more channels 224, 226, 228, turning a knob 230 coupled to stem 232. A valve element 222 of preferred bypass, can be described as a seated cylinder in housing 42, in which the cylinder walls have several holes in precise longitudinal and radial positions, to align with appropriate channels 224, 226, 228 as rotated valve 222. The detailed action of the valve is described. branch 222 in relation to Figures 23A to 23F in what follow.

Figures 23A-F are views lateral, in cross section, of the bypass valve Figure 22, which show their performance at various angles of rotation. Figure 23A shows the bypass valve in a position in which fluid is directed from inlet 45 to the channel 224, substantially without restriction. Therefore the nozzle assembly is in oscillating mode. Figure 23B shows bypass valve in one position (45 degrees in favor of clockwise in relation to Figure 23A, as shown by arrow 234), in which the fluid is directed from the input 45 through holes 225, 229 to both channels 224, 226, respectively. Therefore, the fluid portion directed through one or more channels 226 exceeds the turbine, producing a lower velocity current through the channel 224 and reducing the oscillation speed of the turbine. The figure 23C shows the bypass valve in one position (90 degrees a clockwise in relation to Figure 23A, according to is shown by arrow 234), in which the fluid is directed from the entrance 45 through the holes 229, to the bypass channels 226, thereby eliminating the oscillation of the turbine while maintaining the flow rate through the nozzle set

Figure 23D is the same as Figure 23A. The Figure 23E shows the bypass valve in one position (45 degrees counterclockwise relative to Figure 23D, as shown by arrow 235), in which the fluid It goes from the entrance 45 through holes 225, 227, until both channels 224, 228, respectively. Therefore the portion of fluid directed through one or more channels 228 (such as for a gentle wash mode, the use of a set of standard nozzles or the use of separate output channels in the spray nozzle), exceeds the turbine, giving rise to a more velocity current down through channel 224, and reducing the speed of swing of the turbine. Figure 23F shows the valve bypass in one position (90 degrees against the needles of the clock in relation to Figure 23D, as shown by the arrow 235), in which the fluid inlet 45 is blocked, and the atomizer nozzle is inoperative. It should be recognized that the Incremental rotation of valve 222 can achieve one or more gradual transitions between modes of operation.

Figures 24A-E, 25A-E and 26A-E, are seen schematic cross-section of the bypass valve Figures 23A-E, taken along the lines 24-24, 25-25 and 26-26, respectively.

Referring again to Figure 22, the bypass channel 228 extends through the wall of the housing 42, then opening adjacent to the set of nozzle 48 such that the fluid is directed to a pool of collection 236. Pool 236 empties into exit channels 78 through low pressure and speed through a plurality of holes 238, in order to reduce the overall velocity of the flowing fluid of the output channels 78. The introduction of a current of low speed in order to reduce the speed of the mainstream, it is mentioned here as "wash mode soft".

Figure 27 is a sectional side view cross section of an atomizer head assembly 240 for the fluid control up to a set of fluid outlet channels stationary 244. While bypass valve 242 operates in the same manner as bypass valve 222 of the Figures 22-26, valve 242 has been simplified in by virtue of the elimination of channels 229. The rotation in favor of the clock hands of the valve 242, directs the fluid through of channel 228 and output channels 244. Channels 244 are preferably directed at an angle such that they increase The effective atomization width of the atomizer head assembly 240.

Figure 28 is a sectional side view transverse of an atomizer head assembly 250 which has a bypass valve 252 to reduce fluid around the tube speed 75 through channel 228 to pool 236. The bypass valve 252 also includes a cam shaft 254 (offset from bypass valve in the outward direction the page), which fits with a 256 sleeve that controls the width of atomization of the nozzle assembly by restricting the movement of the oscillating plate 46. As the bypass valve 252 is rotated, cam shaft 254 causes sleeve 256 to descend so that the annular flange 258 comes into contact with the oscillating plate 46, limiting the degree of oscillation and, consequently, narrowing the atomization width, further cuff descent can immobilize the oscillating plate and provide a fluid flow of high impact.

Figure 29 is a side view, in section transverse, of a set of atomizer head like that of the Figure 28, except that sleeve 266 has a flange 268 arranged below the oscillating plate 46. As it is rotated bypass valve 262, cam 264 is caused to raise the sleeve 266 so that the flange 268 comes into contact with the oscillating plate 46, thereby limiting the range of motion of the nozzle assembly, and narrowing the atomization width.

Figure 30 is a side view, in section transverse, of a set of atomizer head 270 having a 272 ring of atomization width adjustment, below the oscillating plate 274. As the adjusting ring 272 is turned on clockwise, the adjustment ring 272 is dragged towards the 276 ring by threaded hitch, and the range of oscillating plate movement 274. All surfaces of the atomizer head assembly 270 contacted by the plate oscillating 274 are preferably forming an angle towards a common point 278, in order to keep post 279 centered on the inside of channel 277.

Figure 31 is a side view, in section transverse, of a set of atomizer head 280 that has a bypass valve 282 (of any known type), for direct water from chamber 43 around speed tube 75, to the nozzle assembly, to achieve a wash soft.

Figure 32 is a sectional side view cross section of an atomizer head assembly 290 which has a oscillation inducing member 292, a limiting member of oscillation 294, and a nozzle 296. The fluid is supplied from chamber 43 through holes 293 and channel 295, up to a external surface of the nozzle 296. Additionally, it has including a bypass valve 282 to provide a Soft, low speed wash current to channel 295.

Figure 33 is a side view, in section transverse, of an atomizer head assembly 300 which is substantially similar to the atomizer head assembly of the Figure 19, except for the addition of a valve 282 soft wash bypass, which supplies fluid to your communication with the nozzle exit channels 286 atomizer The output channels 286 are directed, with preference, so that the fluid leaving the channels 286 is mix with the fluid that comes out of the exit channels 78, but only after the two fluid streams have left the nozzle 288.

Figure 34 is a side view, in section transverse, of an atomizer head assembly 10 that has a set of impact adjustment (speed), arranged current below the speed tube 75. The adjustment set 312 of impact includes a needle valve 314 that can be positioned in speed tube 75 or in another hole, to provide a greater flow restriction and an increase in the speed of the fluid that passes through it. As shown in Figure 34, the assembly 310 may be provided with a grip member 316 appropriate, to stop the oscillation of the nozzle assembly while adjusting the position of needle valve 314. The grip member 316 has been represented as an annular ring which is pushed up by a compressed spring 318. It has provided a handle 320 to allow the user to pull the grip member 316 down, until the surfaces of grip 322 contact the outer surface of the housing of atomization 324, and secure the nozzle assembly in position stationary The tab 326 provided at the end of the valve needle 314, can then be held between the fingers of the user, and turned on. Because the needle valve 314 has been threaded through the center of baffle 328, valve 314 can move forward and backward to obtain a desired degree of fluid impact It is preferred that the threads are made of so that they are tight enough to ensure the needle valve position despite a vibration or prolonged oscillation of the nozzle assembly.

While the above has been directed to the preferred embodiment of the present invention, can be designed other additional embodiments of the invention without departing from the basic scope of the same, and whose scope is determined by the claims that follow.

I. Additional Sets of Atomizer Head that Include a camera

The present invention provides an apparatus equipped with a mobile nozzle that supplies fluid for use in various applications, such as, but not limited to, showers or vortex baths. The movement of the nozzle may include a nutante movement, a rotational movement, a movement arched, a swinging movement or a combination of these movements. The movement of the nozzle is energized by the arrangement of a swing inducing member, such as a oscillating turbine, in the path of the fluid supply in the Interior of an accommodation. Water flowing over the turbine oscillating, makes the oscillating turbine oscillate. Turbine oscillating imparts movement to the nozzle according to a arched path defined. The movement of the nozzle, or at minus redirection of the nozzle outlet, provides a more satisfying vortex bath experience than  stationary nozzles An advantage of the unique turbine design oscillating is that it does not include complex mechanical parts or that cause significant flow restrictions.

An aspect of the present invention provides an apparatus with a swing or turbine inducing member oscillator that is fitted directly with the nozzle. The nozzle can have any number of output channels, but preferably it has less than about five channels of output, and more preferably it has one or two output channels that They direct the fluid with equal or different angles. Turbine oscillating is preferably mounted on a pole located in the inside of a sleeve or track, where the upper surface Conical swinging turbine faces the water inlet. Because the pole has a smaller diameter than the inner surface of the sleeve or track, the number of rotations of the turbine must take place so that each oscillation acts to reduce or control the speed of the oscillation. Cuff it can form an oval receptacle that causes a flattening of the angle of rotation of the nozzle according to an oval axis. Optionally, air can be introduced into the flow path of water as it passes through, or leaves the apparatus, to provide a stream of aerated water for contact with the skin. It should be understood that when the detailed description of the invention discusses an oscillation inducing member that has a post and a nozzle assembly that has a sleeve, the scope of the present invention and of each of the embodiments described also includes the oscillating turbine that has a sleeve and a nozzle assembly that has a pole. In fact, aspects of the present invention can be operable in combination with other coupling members that are capable of support the oscillation inducing member while allowing Turn and rock.

Another aspect of the invention provides a device that can include more than one output channel, but preferably it has two output channels that form angles opposite to the center line of the device. In this arrangement, a swinging turbine is received relaxing in a swinging turbine that is attached to the nozzle, so that as the oscillating turbine oscillates, the nozzle oscillates. Since the nozzle is oscillating in shape independent of oscillating turbine, distribution or coverage of fluid on a surface, it is extremely uniform. The opening of the housing through which the nozzle assembly, has a diameter slightly larger than the nozzle assembly, such that the difference in diameter can be used to determine the rotational speed of the nozzle.

Still another aspect of the invention provides a limiter of oscillation. Optionally, the member swing limiter can be manually adjusted by the user to obtain the desired jet from the apparatus. The swing speed can be adjusted by allowing the Oscillating turbine bends more or less. The degree of inclination affects the radius of the oscillating turbine with which it hits the water stream. A small inclination will result greater number of rotations per minute (rpm) than an incline great for any turbine that has an angle of conicity, a surface area and a given angle / groove size.

The swing limiter members, of according to the present invention, they can be formed according to a diversity of settings to define the offset desired of the oscillation inducing member. These members swing limiters include, but are not limited to, tracks, walls, plates, grooves, sleeves or cylinders, and posts. The invention uses any number of a combination of members oscillation limiters and oscillation inducing members, or even of portions of oscillating inducing members. Examples of combinations include: (a) a turbine pole limited by a sleeve (see Figure 35); (b) a nozzle post limited by a cylinder (see Figures 42 and 43), and (c) a body of turbine limited by the chamber wall (see Figure 38). However, these and other considerations will be apparent. for experts in the field in view of this description, and are included within the scope of this invention.

While the swing inductor member it may be coupled, attached or otherwise secured to a nozzle, it is generally preferred not to integrate or fix the member oscillation inductor to the nozzle. Especially, the mouthpiece It has an end that is proximal to the oscillation inducing member. It is preferred that this proximal end of the nozzle and the member oscillation inducer receive each other according to a relationship lazy male-female, especially when the proximal end and oscillation inducing member can easily slide or pivot in proper relationship without restriction. An especially preferred arrangement consists of a post and sleeve relationship in which a cylindrical post (male) it is received inside a cylindrical sleeve (female), where the external diameter of the post is smaller than the diameter inner cuff Alternatively, the post may form a truncated conical surface (male) received inside a conical cuff (female), where the conicity angle of the Pole is smaller than the conicity angle of the sleeve. Be understand that post can be part of the nozzle assembly, and the sleeve may be part of the oscillation inducing member, or vice versa. It is preferred to design the pole and sleeve with sufficient tolerances between them so that the inducing member of oscillation can oscillate in relation to the nozzle assembly without bonding In addition, it is more preferred to use a oscillation inducing member having a conical post or conical trunk with a first diameter, received in a conical sleeve or frustoconical of the nozzle assembly. Examples of various oscillating atomizer head assemblies, which can be adapted for use in the present invention, they are described in the US 6,092,739, which is incorporated herein as a reference in its entirety.

Another embodiment or aspect of the invention, provides a motor energized with fluid that is capable of driving various devices, such as a nozzle assembly, a sprayer mobile or a secondary pump. This engine is especially useful in applications that require a low output speed due to that the complexity of the reduction gears could be Probably unnecessary. The engine is equipped with a member swing inductor in relation to pole / sleeve with a actuator assembly or nozzle assembly, in which the oscillation of the actuator assembly or nozzle assembly is limited or constrained by means of an oscillating limiter member. While the oscillation of the actuator assembly is limited, it still allows the actuator assembly to rotate inside the oscillating limiter member and that the actuator assembly forms A motor output shaft. The swing limiter member is preferably a groove (which fits with an oscillating plate of the actuator assembly or nozzle assembly), a plate (that fits with an oscillation slot of the actuator assembly or assembly of nozzle), or a cylinder (that fits with a set post actuator or nozzle assembly). The limiter of oscillation will fit with the actuator or nozzle assembly inside of a certain dimensional tolerances to limit the degree of oscillation (maximum angle outside the central axis) imparted to the set. While the degree of oscillation that can be tolerated is expected to be dependent on the intended use of the motor output, the degree of oscillation will usually be lower that an angle of five (5) degrees of center deviation, preferably less than an angle of two (2) degrees of deviation from the center. It should be understood that the motor output shaft can be coupled to any device without limitation, if that device is integral with the shaft (such as an actuator bolt deviated from the shaft), in relation to loose coupling hitch with the shaft, coupled to the shaft, or in relation to temporary clamping or conditional to the axis. A preferred drive shaft includes a step of fluid through it, to form a nozzle assembly. Other axis preferred motor engages with a separate nozzle assembly, of known way, to provide a simple movement (circular, oscillating or alternative, etc.), or complex (elliptical, sweep, etc.), of the nozzle assembly. Said separate nozzle assembly is preferably supported in the housing, on an axis or a fixing the type of ball and socket that extends through the center of the set. The nozzle assembly may have a shape spherical or cylindrical, and a groove may have been designed actuator in the assembly to produce the flow pattern desired coming out of the nozzle.

Another aspect of the invention provides a device that can include more than one output channel, with preference at least one channel that is aligned with the line device center, with the remaining channels positioned forming  angles opposite the center line of the device. Additionally, no the chamber that surrounds the oscillating turbine and the nozzle set is much larger than the set of nozzle. The reduced size provides effective channeling of the fluid with very small losses of speed, causing This design is useful for areas with low water pressure.

In an alternative embodiment, the turbine Oscillating has been fixed to the nozzle assembly. Turbine oscillating rotates in response to the fluid flowing into the chamber and to the fluid flowing out of the nozzle assembly, to Provide a uniform flow pattern. This design is particularly useful in areas with low water pressure, due to that the water entering the nozzle can cause the turbine / nozzle assembly out of the groove or collar, allowing the complete set to rotate easily.

Still in another embodiment of the present invention, the oscillating turbine and the pole, are attached to a nozzle that has a combination of both high and low pressure. Water flows out of the oscillating turbine and to through the post, as described above; however, the water then flows to a high pressure chamber that has high pressure outlets that emit small drops of water at high speeds. A portion of the water is directed to a low chamber pressure through a flow control member, having the chamber low pressure outlets, where larger water drops, to Low speed, leave the nozzle. The big and small drops they leave the nozzle at different speeds, thus producing two patterns of drops that provide the bathroom with uniform coverage and a satisfactory speed of water flow.

It should be understood that the apparatus of the present invention, and the individual components thereof, may be made with any known materials that are resistant to chemical and thermal attack by the fluid that passes into its through. When the fluid is water, the device or components of the apparatus are preferably made from a plastic extrudable or injection moldable, or from a material polymer, more preferably an acetal resin such as DELRIN (a registered trademark of Du Pont de Nemours, E.I. 7 Co. of Wilmington, Delaware). The apparatus may also include components. made from metals or metal alloys, such as steel stainless. Other materials suitable for use herein invention, will be apparent to one skilled in the art and will considers that they are within the scope of this invention.

Figure 43 is a sectional view of another embodiment of the present invention. The apparatus 1044 has a housing 1046 to contain a turbine 1048 similar to the shown in Figure 53. However, oscillating turbine 1048 is is received relaxed in a 1050 sleeve that is part of a nozzle assembly 1052. The housing 1046 forms a camera 1054 with an input 1056 positioned upstream of the oscillating turbine 1048. The ground or distal end 1058 of the accommodation downstream of the oscillating turbine, forms a 1060 collar, hole or opening through to receive slidingly the nozzle assembly 1052, which has a 1062 nozzle extending beyond the 1060 collar, and a 1050 sleeve to support 1048 oscillating turbine.

The 1048 oscillating turbine has a surface 1064 conical top that is attached to a 1066 post. The surface top 1064 of the swing turbine 1048 extends with preference radially beyond post 1066, to form a ring overhang The external diameter of post 1066 is smaller that the inner diameter of the sleeve 1050 such that when oscillates the oscillating turbine inside the sleeve, the oscillation movement is transferred to the nozzle 1052.

The nozzle assembly 1052 provides a elongated portion having a staggering portion 1070 annular, which rests on an optional washer or bearing 1072. The elongated portion of the nozzle assembly has fluid inlets 1074 positioned above the angular stepping 1070, and 1078 fluid inlets positioned below stepping 1070. The elongated portion further forms a step 1068 that provides fluid communication between inlet (s) 1074 and 1078 and nozzle 1062. The 1074 entries consist, with preference, in a plurality of channels that extend through of the nozzle wall, preferably at an angle towards down from the top of the housing 1046 towards the ground 1050 of the accommodation. The 1078 entries extend, with preference, through the wall of the nozzle assembly, preferably forming an angle down and towards the center line  of the nozzle assembly 1052. The nozzle 1062 can provide one or more, preferably two, 1080 output channels in fluid communication with step 1068. The output channels they are, more preferably, angled out about compared to others, off center line of the set of 1052 nozzle

The opening 1060 has an inside diameter simply larger than the outer diameter of the set of 1052 nozzle that extends through it. The difference of diameter acts to control the speed of rotation of the set of nozzle 1052. For example, if the internal diameter of the opening  1060 is 13 mm (0.51 inches), and the outer diameter of the nozzle set is 12.7 mm (0.5 inch), with each 360º oscillation of the oscillating turbine, and therefore a oscillation of the nozzle assembly, the nozzle assembly will rotate 0.798 mm (0.0314 inches) or 1 / 50º of its circumference in opposite direction to the swing, resulting in a complete revolution for every fifty oscillations. In this example, if oscillating turbine 1048 is oscillating at 1800 rpm, then the nozzle assembly 1052 will rotate around 36 rpm

The water flow to the housing 1046, can be regulated by means of a 1082 needle valve or a valve of gate. Additionally, the water flow can be aerated by air drag to the accommodation through the port 1084

Figure 44 is a sectional view of a apparatus 1083 similar to that shown in Figure 43, in which They use equal numbers to designate similar elements. The 1048 oscillating turbine is quietly received in a sleeve 1050 that is part of the nozzle assembly 1052. The housing 1046 forms a 1054 camera with a 1056 input positioned upstream of the 1048 turbine. The floor 1058 of the housing form a collar, hole or opening 160 through it to receive slidingly the nozzle assembly 1052, which has a 1062 nozzle positioned outside the housing and sleeve 1050, to support the oscillating turbine 1048 inside the accommodation. The nozzle assembly 1052 forms a stepping ring 1070 which is located in an adjustable slot 1088. The slot width 1088 can be adjusted using the plate mobile 1087 up or down, thereby limiting the speed of oscillation of the oscillating turbine, and in turn, the speed of oscillation and inclination of the nozzle assembly 1052. Reducing the width of the groove (represented here as the vertical distance of the groove between the floor 1050 and the plate 1087), a small inclination of the 1052 nozzle assembly and high RPM, thereby increasing the width of the groove will result in a greater tilt and lower RPM for the nozzle assembly.

Figure 45 is a sectional view of a alternative apparatus of the present invention. The 1090 apparatus provides 1092 housing to maintain a swinging turbine 1094 and a 1096 nozzle assembly. Housing 1092 forms a 1098 chamber with a fluid inlet positioned upstream of oscillating turbine 1094. Housing 1092 has a floor 1102 defining an opening 1194 through it, to support the nozzle assembly 1096. The oscillating turbine 1094 is is slippery received in a sleeve 1108 that has a upper end open. Accommodation 1092 has a member of support 1110 attached thereto, where the support member 1110 define a hole 1112 therethrough, to receive slidably the lower end of the sleeve 1108. The lower end of the sleeve 1108 has an actuator bolt 1114 that extends from the same, which is located offset from the center of the longitudinal axis of sleeve 1108.

The nozzle assembly 1096 defines an opening or actuator slot 1116 therein, to receive the actuator bolt 1114, so that when turbine 1094 oscillates, the movement of swing is turned into a rotating movement that is transferred to the nozzle assembly 1096 through the actuator bolt 1114. The nozzle assembly has been fixed to the housing around of axis 1097, allowing a movement from side to side with respect to the 1120 nozzle outlet. A ball and socket joint, can be also used to fix the nozzle assembly to accommodation, thereby allowing a circular or arched movement of the nozzle outlet 1120. Alternatively, the shape of the actuator slot 1116 may be designed to produce a swing pattern side by side, or a fluid pattern of shape Oval coming out of mouthpiece. It will be understood that the set of Swing / sleeve / support / bolt actuator, can be considered as a water driven motor, which can drive any number of devices known to experts in the matter.

The nozzle assembly 1096 defines a step of fluid that is in fluid communication with a plurality of 1118 fluid inlets inside the housing, and a channel of fluid outlet 1120 outside housing 1092. The 1118 fluid inlets preferably extend through the 1096 nozzle assembly wall, forming a slight angle. He 1096 nozzle assembly can be spherical, round, elliptical or oval, depending on the desired water flow pattern at the outlet of the nozzle or fluid outlet channel 1120.

During use, the water contacts the part top of oscillating turbine 1094 causing it to oscillate in the inside the sleeve 1108. The sleeve 1108 oscillates in turn, generating rotation from your contact with the member of support 1110, moving the actuator bolt 1114 according to a movement in general, where the center of the actuator bolt is not aligned with the longitudinal axis of sleeve 1108. As per shown in Figure 56, the oscillating sleeve 1108 acts as motor to rock the nozzle assembly 1096 in a movement of front back around axis 1097, to produce a pattern of sweep of the water coming out of the nozzle 1120.

The water flow can be aerated through the Air supply to the chamber through a port. The flow of water to the chamber can be restricted with the activation of a needle valve represented, or a gate valve as It has been discussed above.

Figure 46 is a sectional view of a mobile jet outlet that could be used in the set of nozzle instead of the 1080 output channels shown in the Figures 2 and 3. The end of the nozzle assembly 1052 may be adapted to receive a 1081 outlet dispenser that has a plurality of channels that extend through it. The supplier of exit 1081 can form a ball secured to a socket so that the angular position of the outlet spout 1081 can then be adjusted by the user with their hands. Preferably, the ball is secured to the socket under sufficient friction to avoid a relative slip during use, but can be adjusted easily by a user. The output channels formed in both ball independent hemispheres, can be positioned forming a divergent angle from each other, as shown in the Figure 2, or essentially in parallel with each other. An expert in matter will appreciate the multitude of usable angles for The output channels.

Figure 47 is a sectional view of another embodiment of the present invention. The apparatus 1156 has a housing 1158 to contain an oscillating turbine 1160 similar to the one shown in Figure 1. However, oscillating turbine 1160 it is received relaxed in a sleeve 1162 that is part of the nozzle assembly 1164. Housing 1158 forms a chamber 1166 with an input 1168 positioned upstream of the turbine swing 1160. The floor or distal end 1170 of the housing form a necklace, hole or opening 1172 through it, to receive slidingly the nozzle assembly 1164, which has a 1174 nozzle communicating outside the housing and the 1162 sleeve to support the 1160 swing turbine inside of accommodation.

The 1160 oscillating turbine has a surface conical upper 1176 similar to that described in Figure 1, that is, attached to a post 1178. The upper surface 1176 of the oscillating turbine 1160 extends, preferably, beyond of post 1178 to form an annular projection. External diameter of the 1178 slightly truncated conical post, it is smaller than internal diameter of the conical surface of the sleeve 1162, such that when the oscillating turbine inside oscillates of the sleeve, the oscillating movement is transferred to the set of 1164 nozzle

The nozzle assembly 1164 provides a 1180 portion of annular stepping, which rests on the floor of the housing, with 1182 fluid inlets positioned by above the annular step 1180, and forms a step 1184 that is in fluid communication with the inlet (s) 1182 and with the nozzle 1174. The entries 1182 form, with preference, a plurality of channels that extend through the wall of the nozzle. The nozzle has a plurality of output channels 1186, in fluid communication with step 1184. Preferably, one of the output channels 1186 is in relation of alignment with the center line of the nozzle assembly, and the remaining output channels are forming outward angle each in relation to the others, deviated from the center line of the nozzle assembly 1164.

The opening or collar 1172 has a diameter inside slightly larger than the outer diameter of the 1164 nozzle assembly. This difference in diameter acts to control the rotation speed of the nozzle assembly 1164

The water inside the accommodation 1158 can exit below the nozzle, between the nozzle and the collar 1172, causing a random atomization to be emitted from the nozzle set In order to avoid the formation of a water pressure between the collar and the nozzle, you can form a groove 1188 in the nozzle assembly 1164. So so much, when the water descends out of the nozzle, the groove will relieve pressure and allow water to pass along from the outer surface of the nozzle, to gather the water that It comes out of channels 1186.

Figure 48 is a sectional view of a apparatus 1157 similar to that shown in Figure 47, where the parts Similar carry the same number. In this embodiment, you can form a groove 1190 in collar 1172, to get the same result than in the apparatus shown in Figure 47. Additionally, the slot can be provided with an element sealant 1191, such as an O-ring, etc., to prevent the water out. The tip of the nozzle 1174 may be made of, or coated with an elastic material 1175, such as rubber, so that the tip of the nozzle can be flexed to break and eliminate Lime or other mineral deposits easily.

Figure 49 is a sectional view of a apparatus 1200 similar to that shown in Figure 47, where Similar parts carry the same number. The apparatus 1200 has a housing 1158 to contain an oscillating turbine 1160. The 1160 oscillating turbine is quietly received in a sleeve 1162 that is part of the nozzle assembly 1164. The 1170 floor of the housing forms a collar, hole or opening 1172 through it, to slidably receive the nozzle assembly 1164, which has a nozzle 1174 that extends through the housing and sleeve 1162 to support the oscillating turbine 1160 inside the accommodation. Nozzle assembly it also includes a sleeve 1202 that forms an annular step 1204 that rests against the floor 1170 of the housing. Cuff 1020 has an external diameter that is smaller than the diameter internal of the collar 1172, such that the sleeve 1202 and the 1164 nozzle assembly are free to rotate inside the necklace. The nozzle assembly forms a plurality of entries of fluid 1206 that are connected to a plurality of outputs 1208 a through steps 1210.

When the fluid is supplied to the housing through inlet 1168, fluid pressure pushes down on oscillating turbine 1176, compressing the spring 1204 and pushing the nozzle 1174 down, so that fluid outlets 1208 extend beyond the end bottom 1214 of sleeve 1202, and release the fluid. When cut off the fluid flow, spring 1204 forces the nozzle up, pushing outlets 1208 toward sleeve 1202 to prevent deposits of lime or other minerals from forming in the 1208 nozzle outlets. With proper configuration of the fluid inlets 1206, this action can also be used to regulate the flow so that it is constant even when they can vary network pressures.

The collar 1172 can also form a groove 1216, similar to the one shown in Figure 47, to release Water pressure and avoid random sprays. 1202 sleeve it can also have a slot to achieve the same effect as slot 1216.

Figure 50 is a cross-sectional view. of an apparatus 1270 of the present invention. The 1270 apparatus has a housing 1272 to contain a 1274 oscillating turbine. The housing 1272 forms a chamber 1276 with an entrance 1278 positioned upstream of the 1274 oscillating turbine. The ground 1280 of housing 1272 forms a collar, hole or opening 1282 through it, to slidably receive a post 1284 that is fixed to oscillating turbine 1274 inside housing 1272, and a nozzle 1286 outside the housing 1272. The post 1284 is keeps in oscillation ratio inside the opening 1282 by means of an annular step 1288 that allows the Pole 1284 bends and rotates inside the opening 1282. This embodiment employs contact rotation-generator, swing-limiter where does contact that sleeve extension of post 1284 and the wall that is extends inside, and forms a contact surface 1285, such as a flexible or high friction surface such as a ring in O, or other suitable structure.

The 1274 oscillating turbine has a surface conical upper, and is similar to the oscillating turbine shown in the Figure 48. Post 1284 provides a 1290 step in communication of fluid between the fluid inlet 1292 and the nozzle 1286. you should appreciate that the particular 1274 oscillating turbine here sample, it is not limiting, since any of the oscillating turbine / pole configurations here are show.

The 1286 nozzle has a 1294 high chamber pressure, which is in fluid communication with step 1290, and a plurality of 1296 high pressure output channels. The camera high pressure 1294 defines an opening 1298 that is in communication of fluid with a 1300 low pressure chamber. The 1300 chamber of Low pressure has 1302 low pressure output channels. A portion of water circulates through chamber 1294 high pressure, to the 1300 low pressure chamber, where the nozzle at a lower pressure than the water leaving the chamber high pressure, thus forming large drops. The water that comes out of the  1296 high pressure output channels, form smaller drops that the water leaving the exit channels 1302 low Pressure.

Therefore, the fluid follows a path to enter chamber 1276 through entrance 1278, passing over 1274 oscillating turbine, entering through entry 1292 in step 1290 of post 1284. The fluid exits after the nozzle 1286 through either the 1296 high output channels pressure, or output channels 1302 of low pressure. In operation, a source of fluid under pressure is in communication with entry 1278 of housing 1272. Pressure of the water that enters the housing 1272, exerts forces on the post 1284, pushing post 1284 down and allowing The turbine oscillates. The 1274 turbine oscillates due to the fluid that flows over the upper surface of the 1274 oscillating turbine. A Once the chamber has been substantially filled with water, the water enters through the entrance of the post, and circulates through a passage of the post to the outlet channels of the nozzle. This design is especially useful for use with high water currents pressure, to produce drops at low and high pressure, providing a globally uniform shower to take baths and the like. The Large drops, lower speed, help eliminate any pulsating sensation of the drops at high pressure, because they are out of sync with the high pressure drops.

Figures 51, 51A and 52 are sectional views. transverse of two alternative coupling designs that can be used to harmonize the movement broken-nutational motor output shaft, or 1164 nozzle assembly, and use that movement to make rotate a gear or shaft, respectively, that has a true axis of rotation. In both Figures 51 and 52, housing 1158, the 1160 oscillating turbine and 1164 nozzle assembly are essentially the same as in the apparatus 1157 of Figure 8, and use the same reference numbers for the elements Similar. The differences between 1310 and 1330 engines, for one part, and section 1157, on the other hand, are aimed at additional members subject to nozzle assembly 1164 instead of the nozzle 1174, and to the additional member attached to the floor of the accommodation 1158.

In Figure 51, the nozzle assembly 1164 It has an extended pole 1312, fitted with a type joint "universal" that provides at least two degrees of freedom which can house the oscillating movement of the nozzle assembly  1164. A bolt 1314 is pivotally engaged through from the side of post 1312, or alternatively held in a manner pivotable next to post 1312. The outermost ends of the bolt 1314 are hooked ivotably with an annular ring 1316 which has double tabs 1318 that extend radially from it. The tabs 1318, in turn, are engaged pivotally with another ring ring 1320 that has holes 1322 pilot through. The annular ring 1320 is maintained in true axial alignment by a cylindrical bearing 1324 fixed to the bottom of floor 1170 of housing 1158. Ring 1320 it can then be coupled to, or include several, means actuators, including 1326 gear teeth arranged around the perimeter of the ring.

In Figure 52, the nozzle assembly 1164 it has a shortened pole 1332 that has a central opening 1333 in the same. A shaft 1334 is maintained in true axial alignment by means of a cylindrical bearing 1336 fixed to the floor 1170 of the housing 1158. Shaft 1334 includes a pole 1338 that extends towards opening 1333. Post 1338 includes double tabs 1340 extending radially therefrom, towards a groove 1342 formed inside the opening 1333 of the nozzle assembly 1164. An important aspect of the invention is that the 1330 engine is driven by fluid that does not flow through a nozzle, but it exits through a separate port 1344 and, Depending on the application, you may not need any camera in absolute. A separate port of that type may be incorporated into housing 1158 of Figure 51, the post 1312 being with plugged preference.

Designs devoid of camera

The present invention provides an apparatus of fluid discharge that supplies fluid according to a distribution of substantially uniform atomization. The movement of the device is an oscillating movement, preferably combined with some rotatory motion. The oscillating movement is generated by withstand an oscillating inductor member or oscillating turbine, in the path of the fluid supply with a body member, which perhaps includes racks, beams, an accommodation, and / or others structural members Unlike with typical nozzles based on an opening, the body does not need to contain pressure or be fluid tight, and in fact can be substantially open. The water flowing over the oscillating turbine causes the swing turbine turn and swing. The oscillating turbine affects then to the direction of the atomization pattern that leaves the atomizing nozzle, distributing the fluid according to a pattern rotating around the axis of the device. Fluid flow distributed, coming from the oscillating turbine, is intercepted by a deflector and redirected down. The passage of the turbine oscillating and the baffle, are chosen so that they minimize the loss at the moment of the fluid flow. According to the invention, the baffle can be provided in any appropriate way, such as by means of an integral part with the body or the turbine oscillating, or as a completely separate component.

The atomization pattern produced by the turbine oscillating changes more or less quickly so that they are directed currents or drops of fluid, along arched paths over time, instead of continuously to a single point. This type of atomization pattern is more pleasant than many stationary patterns, and the unique design of the oscillating turbine not includes complex mechanical parts or flow restrictions significant. It may be desirable to incorporate dividers in the baffle in order to divide the fluid flow into a plurality of discrete fluid streams.

Another embodiment of the present invention provides a fluid discharge apparatus equipped with a oscillation inducing member, or oscillating turbine, which causes that the body or housing that supports the turbine or member swing inductor, also swing. More particularly, the oscillation inducing member is arranged in relation to relaxed contact with the body or housing of the device, thus reducing the number of pieces necessary to achieve such movement, and increasing the capacity of the apparatus to produce a desired spray pattern and width, such as for a tap or a shower in a house. The fluid is distributed out of the surface of the turbine according to a rotating pattern, and to then it moves without flow restriction on the baffle down to the exit of the device, whose output may be substantially open or may include non-restrictive dividers or channels in any number and with any configuration. According used here, the term "descending" or "down" means that the flow distributed out of the turbine oscillating, with a first angle in relation to the center line axial of the fluid inlet, is directed so that the fluid change its direction to a second smaller angle in relation with the axial center line of the fluid inlet.

While you can conceive that the turbine oscillating distributes the fluid with a first angle which is something less than 90 degrees, the turbine can distribute fluid with a angle less than 60 degrees from the axis, preferably less than 45 degrees from the axis, and more preferably between about 30 degrees and about 40 degrees from the axis. The baffle can receive or intercept the distributed fluid from the turbine, with an angled surface similar to the first angle with the one that distributes the fluid outside the turbine. Further, While the deflector can redirect the fluid there are many angles, even angles towards the axial centerline instead of out of the axial center line, the baffle must have a smooth tilt, gradually changing, to redirect fluid towards a more hermetic discharge pattern than the one it would provide Any other turbine. Preferably, the deflector will redirect the fluid with an angle within about +/- 20 degrees of a line parallel to the axial center line, and even more  preferably the deflector will redirect fluid according to two or more angles, such as having twelve channels 66 with four of they forming an angle of 0 degrees, and the other eight in angles of 10 degrees. It should be understood that, since the turbine oscillates and some embodiments of the deflector will oscillate dependently or independent of the oscillating turbine, the relative angles and the  combinations of turbine and deflector angles are constantly changing and are more dependent on the degree of swing allowed by the design of its connections, that is, the dimensions of a pole and sleeve, or an oscillating ring plate and the space limiter member, etc. Finally the surfaces of the turbine and the baffle are preferably concave with the in order to achieve a gradual transition of the direction in which water flow occurs with momentum losses that are only minimal, and without excessive splashing or fogging of the Water.

Preferably, the inducing member of oscillation or oscillating turbine, is arranged in relation to coupling or direct contact with the body of the device. More in in particular, the body member supports the oscillating turbine in ratio of axially separated from the fluid inlet, if the support causes a mechanical bond, such as an arrangement of type flexible connector or ball and cage, or a loose relationship of male-female, such as the preferred ratio of post and sleeve. The term "pole and sleeve relationship", as used here, includes any of a number of configurations in which a pole (male connector), which forms a cylindrical, conical or truncated surface, is received Relaxing inside a sleeve (female connector), which it forms a cylindrical, conical or truncated conical inner surface, to allow the oscillation between them to occur. The lower surface of the pole is preferably rounded or formed in any other way to minimize friction and linking between members. It should be understood that the cuff it can be formed as an integral part of the body or housing, and the post may be part of the oscillation inducing member, or vice versa. It is preferred to design the pole and sleeve with sufficient tolerances between the two, so that the member oscillation inducer can oscillate in relation to the body or accommodation without linking. In addition, it is better preferred to use a post and sleeve ratio having a conical surface or conical trunk on at least a portion of the pole with a first diameter for rolling pole hitch with a conical surface or truncated cone on at least a portion of the sleeve that has a slightly larger diameter supported in axial relation separated from the fluid outlet. Conical or truncated conical surfaces they must have a common cusp in order to the surfaces Get in full rolling contact.

The oscillating turbine can be supported by the body, frame or housing of the device of any configuration, but preferably supported by a series of thin fins, preferably three or four, that extend radially from the body wall, frame or housing, positioned below the output channels. The use of fins thin is usually enough to support the turbine oscillating without providing any significant restriction to global fluid flow Alternatively, the oscillating turbine it can be supported by a simple arm that extends to along one side of the device.

The device has shown the ability to operate with a reduced water flow rate, while it has provided a satisfactory stream of water that is particularly useful in a sump tap. Due to the action oscillating, distribution or coverage of fluid discharged out of the apparatus on a surface, it is extremely uniform and can be characterized as a fluid distribution broken-nutational as stated in the request for  U.S. Patent Series No. 09 / 115,362, which is incorporated here as reference. Therefore, the distribution pattern allows the device has fewer channels and are less restrictive, with greater cross-sectional area to make it less likely that are restricted or plugged with lime, or other particles or mineral deposits

While the degree of oscillation may be limited by tolerances between a pole and a sleeve, or between an oscillating plate and a space limiter member, the apparatus it may also optionally include a limiter member of active swing An active swing limiter member, such As a tracking ring, it operates as a self-centering mechanism for the oscillating turbine.

It should be understood that the apparatus of the present invention, and the individual components thereof, can be of any known materials, preferably those materials that are resistant to chemical and thermal attack by part of the fluid that passes through it. When the fluid is water, the  Preferred materials include plastics, such as one or more injection moldable materials or extrudable polymers, more preferably an acetal resin, and metals or alloys metallic, such as stainless steel. Other suitable materials for use in the present invention may be apparent to subject matter experts, and are considered within the scope of The present invention.

Figures 36 to 38 are top views of several conical upper surfaces 558 of a 554 turbine. The upper surface 558 of oscillating turbine 554 has been illustrated provided with spans 560 formed according to a configuration not radial. It should be appreciated that the fluid flow that impacts on the oscillating turbine will push the oscillating turbine to one side, towards an inclined position, so that the center point of the oscillating turbine will be substantially out of the current of fluid coming from the inlet, and only one side of the turbine oscillating aligns with the fluid stream at any time in the time. Each of the 560 spans formed on the surface top of oscillating turbine 54, are non-radial, and cause that the 554 oscillating turbine orbits around the entrance of fluid 550 as the fluid flows against the openings 560. The openings do not 560 radial, conical surface and relaxation ratio between the pole and the sleeve, ensure that when the fluid flows against the top of the swing turbine 554 under pressure (even low pressure), the oscillating turbine will lean towards out of center, and the swing will begin. Especially the fluid that hits the conical surface 558 of the turbine, originates a tilt force, and the fluid that passes through the vain 560 gives rise to rotational forces. Therefore, the fluid stream that passes through the inlet causes it to oscillate the oscillating turbine.

Once the oscillating movement starts, the continuous flow of water keeps the turbine oscillating in mode of oscillation. In addition, fluid flow also causes a force descending push down the turbine, tending to keep the turbine against a displacement of its cooperative relationship with the cuff Therefore, it is preferred that the angle of the 558 conical surface is large enough to produce at least a slight tilt force even when the turbine is already fully inclined, but not so large as to cause the turbine to push up and out of your contact with the sleeve. It should be understood that each of the embodiments of Figures 36 to 39 may also be effective if the oscillating turbine comprises a sleeve (instead of a pole) and the atomization housing comprises a pole (instead of a sleeve) for its coupling with the turbine sleeve oscillating

For any given oscillating turbine, the speed or oscillation ratio can be increased (or reduced) with the increase (or reduction) in the speed of fluid flow through the atomizer head. However it is possible to design the oscillating turbine so that it has a speed faster or slower oscillation for a flow rate of given fluid, changing the angle or pitch of the slots or spans of the oscillating turbine, or changing the relative dimensions of the post and sleeve or other similar oscillating means or swing limiters.

With reference to Figure 36, a turbine oscillating can be designed so that it has a speed of generally lower swing, reducing the pitch and the depth of the openings, that is, designing the openings 560 with a small angle, β, with respect to the radius. Similarly, the oscillating turbine can be designed so that it has a faster swing speed increasing the passage of spans, that is, designing the spans with a greater angle, δ, with respect to the radius, as shown in Figure 37. In addition, the number or separation and size of the openings, can be modified to accommodate an oscillating turbine, as shown in Figure 38, in which the 560 spans are quite separate, allowing that a significant portion of the water passes over the turbine without impact on any of the alters 600 and therefore providing less angular movement to the turbine.

Figure 39 is a bottom view of a head atomizer that shows the output channels of the housing. While the output channels can be provided from in any manner known in the art, a preferred set of output channels 604 are defined by a plurality of ribs or dividers 606 connected to the inner surface 610 of the 542 atomization housing. Four 608 fins have been fixed to housing 543, and extend radially inwardly to support the sleeve 570. It is preferred to direct a portion smaller of the output channels 604 with a smaller angle to the axis of the atomization housing 542, in order to provide a more uniform atomization or coverage pattern on an object to a short distance from the atomizer head, such as a person who  he is taking a shower. The lower angle output channels are preferably form at separate intervals around the perimeter of the spray nozzle, or in radially positions inside, towards the central axis of the atomization housing (no represented).

Figures 40 and 41 are sectional views of a apparatus 620 in which the oscillating turbine 622 defines a hole 624 extending through the top of the turbine 558, and through post 556, preferably along the axis turbine center. The lower end of the sleeve 546 defines an opening 626 therein. A valve element 628 is It is arranged at the lower end of the sleeve 546, and acts to change the flow of water that leaves assembly 620 of shower head The valve element can adopt any number of ways, including shut-off valves, valves needle, butterfly valves, gate valves, and the like, but in this case it has been shown as a gate valve manual or sliding element 628. When the sliding element 628 is in the open position, water flows through hole 624 of the oscillating turbine 622, and out of the opening 626 of the sleeve 546. The flow pattern provides a compact current of water that is useful for cleaning a razor, a Toothbrush, or other object. As shown in Figure 41, when the sliding element is in the closed position, the water will is forced to flow over the turbine, and out through of the output channels 566. Alternatively, the surface inside 548 near the bottom end of sleeve 546, can be tapered inward so that when the element Slider 628 is in open condition, the turbine falls slightly  to be insured by the accommodation, such as through the sleeve that grabs the pole and / or hooking the housing of Safely the bottom side of the oscillating turbine head. Be you should appreciate that any of the realizations that are here are show, can be adapted for use with an oscillating turbine similar that has a hole through it, and a valve element to provide a narrow stream of water out of the apparatus.

Figure 42 is a sectional side view cross section of an apparatus 640 in which the sleeve 546 is supported from fluid inlet 550, by means of an element 642 cage or saddle. The oscillating turbine 622 is similar to that shown in Figure 14, with a hole 624 that extends through. The cage 642 supports the sleeve 546 of such so that the cage and the sleeve do not move when the turbine swing 622 and housing 642 are moving. Cage 642 comprises arms 646 that are attached to fluid inlet 550 and to sleeve 546. Arms 646 have a cross section thin, so that they do not interfere with the flow of water that comes out of the 640 set. A 648 oscillation limiter ring, for limit the oscillation of the turbine 622, extends from the water inlet 50 to a point just above the oscillating turbine 622, so that the conical upper surface of the oscillating turbine can contact the inner surface of the ring 648. The degree of oscillation for housing 542, is similarly limited by oscillating ring plate 544 and the 552 collar or half space limiter, including a 650 plate swing limiter that contacts the top of the 542 housing to limit the degree of oscillation, allowing that way a stream of compact water as in Figure 48. The 650 swing limiter plate can be adjusted longitudinally to allow varying degrees of oscillation to the accommodation 542.

While the above is addressed to the preferred embodiment of the present invention, can be devised other embodiments of the invention without departing from the scope basic of the same, and whose scope is determined by the claims that follow.
