Definitions
- Water flowing through one of the flow paths is di- Colhns, COIO- rected against a turbine blade assembly to drive a rotat- [22] Filed: June 21, 1972 able valve rotor in rotation at a rotary speed dependent upon the pressure of water following this flow path.
- the rotating valve port remains constant regardless of the rotary position of the valve port.
- the present invention is especially directed to the provision of a spray nozzle or showerhead which is operable to produce a pulsating or intermittently interrupted spray with no variations in back pressure exerted by the nozzle, thereby eliminating water hammer, and in which the rate of pulsation may be readily adjusted independently of the pressure of water supplied to the nozzle.
- a nozzle embodying the present invention includes a hollow cylindrical housing having a hollow cylindrical valve rotor supported for coaxial rotation between opposed end plates of the housing.
- An inlet tube is connected to supply water to the outer side of one of the housing end plates. Water from the inlet can pass through the inlet end plate through a first axially extending passage and also through a series of tangentially inclined passage ways.
- the tangentially inclined passage ways are aligned with an annular ring of turbine blades mounted on the valve rotor so that water discharged from the inclined passages impinges on the turbine blades to drive the valve rotor in rotation and passes through spaces between the blades.
- the end wall of the valve rotor in which the turbine blades are mounted also carries a series of axially extending passages located to conduct water discharged from the axial passage in the housing end plate.
- the axial passages and the inclined passages thus define two separate flow paths for water to flow from the inlet tube through the rotor to be recombined downstream of the rotor end wall. Apportionment of the inlet flow between these two flow passages is achieved by a shutter type valve which can be adjustably positioned to provide a variable restriction to the axially extending passage in the housing end plate.
- the valve rotor is a hollow cylinder, the turbine blades being formed in one end wall, and the opposite end wall of the valve rotor is formed with a valve opening or port in the shape of a segment of an annulus.
- This latter end wall of the valve rotor is located in substantial face to face engagement with the corresponding end wall of the housing.
- the nozzle discharge orifices are bored through the end wall of the housing and arranged in symmetrically spaced groups, identical in pattern, which lie within the annular path traversed by the valve port.
- the angular extent of the annular valve port is determined by the number of groups of orifices, the angular extent of the port being equal to 360 divided by the number of groups of orifices or a whole multiple thereof.
- the number of orifices exposed or uncovered by the valve port remains constant, regardless of the angular position of the rotating valve port.
- the rotating valve port uncovers and closes the orifices in succession as it is driven in rotation, thus intermittently interrupting the stream discharge from each individual orifice to produce a pulsating effect inthe stream.
- a floating wear plate of a material having a low coefficient of friction may be inserted between the housing end wall and a recess formed in the adjacent end wall of the rotor.
- valve rotor may take the form of a shaft fixed to the turbine, the opposite end of the shaft being received in a stationary hub on the interior side of the housing end wall.
- Each group of discharge orifices is connected via an internal chamber in the hub to symmetrically spaced inlet ports opening into the bore of the hub in which the valve rotor shaft rotates.
- An axially extending groove in the shaft functions as the valve port.

- FIG. 10 is a cross sectional view taken on line 10-10 of FIG. 9.
- One form of spray nozzle shown in the drawings includes a main connector tube designated generally I whose upper portion, as viewed in FIG. I, is formed with a relatively small diameter inlet passage 12. At its lower end, connector tube is formed with an enlarged diameter housing portion 14 whose open lower end is closed by an orifice fitting designated generally 16 threadably received within housing portion 14.
- a flow directing plate designated generally I8 is keyed in fixed position within the interior of housing portion 14 between the inner end 20 of fitting 16 and a shoulder 22 formed within housing portion 14. Water flowing downwardly through inlet passage I2 can pass through flow directing plate 1% via an axially extending passage 24 and also through a plurality of tangentially inclined passageways 26 which extend through plate 118.
- orifice fitting 16 and flow directing plate 18 cooperatively enclose a cylindrical chamber 28 whose upper wall is defined by plate 18 and whose lower wall is defined by the bottom plate 30 of the cup shaped orifice fitting 16.
- the outlet of chamber 28 is formed by a plurality of relatively small diameter bores 32 through bottom plate 30 of fitting 16.
- a hollow cylindrical valve rotor designated generally 36 is mounted for coaxial rotation within chamber 28 by a projecting shaft 38 at its upper end received within a central bore 40 in plate 18 and by a ball 42 retained within opposed conical recesses formed in bottom plate 30 and the bottom wall 413 of valve rotor 36.
- valve rotor 36 is formed with an annular series of turbine blades 46 located in an annular band near the outer periphery of plate 44 in alignment with the lower ends of passages 26, water discharged from the lower ends of passages 26 impinging on the inclined turbine blades 46 to drive valve rotor 36 in rotationv
- Axially extending bores 48 are also formed to extend through upper plate 44 at a radial position such that bores 48 are aligned with passage 24 in flow directing plate 18 as valve rotor 36 is driven in rotation.
- Valve rotor 36 substantially fills chamber 28, and thus substantially all water passing through flow directing plate 18 either via passage 24 or passages 26 passes into the interior of valve rotor 36 either through bore 48 or through the spaces between turbine blades 46.
- a valve port 50 is cut through bottom valve 43 of valve rotor 36 to accommodate flow of water from the interior of rotor 36.
- valve port 50 is shaped in the form of an annular segment coaxial with the axis of rotation of rotor 36.
- the discharge bores or orifices 32 in bottom plate 30 are located in three symmetrically arranged groups about the central axis of orifice fitting 16, the groups of orifices 32 all falling within the annular path of movement traversed by valve port 50 of valve rotor 36.
- the radial extent of annular valve port 50 is selected to radially overlap the various groups of orifices 32, while the angular extent of port 50 is equal to 360 divided by the number of individual groups of orifices. In the embodiment shown in the drawings, three groups of orifices are employed, and therefore the angular extent of port 50 is 120.
- valve 52 To adjustably apportion the flow from inlet passage 12 between passage 24 and passages 26, a shutter type throttling valve designated generally 52 is employed to act as an adjustable closure for the inlet of passage 24.
- valve 52 includes a shutter like valve member 54 fixedly mounted upon a shaft 56 journaled for rotation in housing portion 14 immediately above plate 18.
- a valve lever 58 is fixedly mounted upon shaft 14, and by manipulation of lever 58, flow from inlet passage 12 through passage 24 may be adjustably throttled in accordance with the degree by which valve member 54 overlies the upper end of passage 24.
- An external casing for the nozzle includes a lower casing member 60 formed with a flange 62 clamped between the lower end of housing portion 14 and a shoulder 64 on orifice fitting 16.
- a coupling ring 66 is detachably mounted upon the upper end of lower casing member 60. Ring 66 is formed with an inwardly projecting ear 68 which forms a sliding support for actuating lever 58, ring 66 being notched to accommodate movement of lever 58.
- An upper casing member 70 engages the upper surface of ring 66 and is formed with an internally threaded sleeve 72 at its upper end for engagement with of main connector tube 10.
- a downwardly facing conical seat 74 at the upper end of upper casing 70 is employed to detachably couple a pivot ball adapter 76 of conventional construction to the upper end of main connector tube 10.
- the spray nozzle is coupled, by means of pivot ball adapter 76, to a supply conduit (not shown) in the same manner as a conventional showerhead.
- the temperature and pressure of water flowing into inlet 12 from the supply conduit via pivot ball 76 are adjusted in the conventional manner.
- water from inlet passage 12 passes through the stationary flow directing plate 18 either via passage 24 or inclined passages 26.
- the direction and location of passages 26 is such that water flowing through passages 26 is discharged to impinge on the inclined blades 46 of valve rotor 36, thus causing the valve rotor to rotate at a velocity which is dependent upon-the velocity at which water is discharged from passages 26.
- Water which does not pass through passages 26 must pass through passage 24 and thence through bores 48 in the rotating rotor 36.
- passages 24 and 48 bypasses the turbine blades and does not exert any effect on the rotating valve rotor 36, except possibly to exert a slight drag or resistance to rotation of the rotor.
- the rotative speed of rotor 36 may be adjusted independently of the supply pressure by adjusting the degree to which valve member 54 overlies passage 24.
- Passage 24 may most conveniently be considered to be an adjustable venting orifice for venting the pressure withing inlet passage 12.
- valve port 50 opens and closes the respective groups of orifices 32 successively as port 50 is driven in rotation thus intermittently interrupting the stream flowing from each individual orifice 32. This intermittent cyclic interruption of each of the individual streams from the nozzle produces a pulsating action on the surface or area of the body against which the stream is directed.
- the nozzle is shown with three groups of orifices 32 and with the angular extent of valve port 50 thus being 120.
- This particular arrangement may be considered to be a preferred one, although this preference is based on the rather subjective test of what appeared to be the most pleasant massaging action.
- the number of discharge orifices 32 was increased to cover the entire annular band traversed by the valve port, the resulting effect was similar to that which might be achieved by moving a conventional showerhead in a circular path.
- the stream from each individual orifice 32 is turned on for one-third of a revolution of the valve rotor and turned off during the remaining two-thirds of the revolution.
- This ratio of on time to off time produces a definite pulsating sensation which apparently spreads over an area somewhat greater than that actually struck by the stream.
- Variation of the rate of pulsation by adjustment of shutter valve 52 may be modified further by the degree to which orifice fitting 16 is tightened into housing portion 14 to thus vary the frictional resistance to rotation of valve rotor 36.
- FIGS. 7 and 8 A modified form of spray nozzle is disclosed in FIGS. 7 and 8 which differs from th previously described embodiment by a modification to the valve rotor. Because ofthe offset location of valve port 50 in bottom wall 43 of valve rotor 36 of the embodiment of FIGS. 1 through 6, the forces developed by the pressure of water against bottom wall 43 are not uniformly applied about the axis of rotation. These unbalanced forces applied to that portion of bottom wall 43 diametrically opposite valve port 50 tend to tilt valve rotor 36 about its axis in a direction lifting that portion of bottom wall 43 through which valve port 50 passes upwardly away from the lower end wall of orifice fitting l6, while at the same time pressing the diametrically opposite portion of bottom wall 43 downwardly against the lower end wall of fitting 16. Over a period of time, the underside of bottom wall 43 opposite valve port 50 can become worn, thus permitting even further tilting of the rotor.
- FIGS. 7 and 8 The embodiment of FIGS. 7 and 8 is designed to minimize wear resulting from the application of the unbalanced force described above. Because the modification of FIGS. 7 and 8 involves primarily a change in the shape of bottom wall 43 and the addition of a floating wear plate, only the housing and valve rotor have been illustrated in FIGS. 7 and 8, it being understood that the remaining structure of the showerhead will be identical to that of the embodiment of FIGS. 1 through 6. In FIGS. 7 and 8, parts common to the FIG. 1 through 6 embodiment have been identified by employing the same reference numerals with a subscript 0 added.
- bottom wall 43a is formed with an upwardly offset portion which extends circumferentially of the rotor for approximately 240 between shoulders 82 (FIG. 8). That portion of bottom wall 43a through which valve port 50a extends is stepped downwardly from offset portion 80 so that when valve rotor 36a is mounted within orifice fitting 16, only portion 84 is in face-toface contact with the inner surface of the fitting end wall, while portion 80 of bottom wall 43a is spaced upwardly above the fitting end wall.
- a floating wear plate 86 is placed within fitting 16a to ride within the recess between shoulders 82.
- Wear plate'86 is preferably formed from a material having a low coefficient of friction, such as polytetrafluoroethylene, and, upon rotation of rotor 36a, which. is driven in rotation with the rotor by one of the shoulders 82. Because of its low coefficientof friction, wear of floater 86 is minimized.
- FIGS. 9 and 10 Still another form of nozzle is shown in FIGS. 9 and 10 in which the wear problem presented by the unbalanced pressure forces is minimized by applying these forces radially against a shaft bearing.
- the embodiment of FIGS. 9 and 10 differs from that of FIG. 1 solely by modification of the valve rotor and orifice fitting, hence much of the structure shown in the FIG. 1 through 6 embodiment has not been duplicated in FIGS. 9 and 10.
- Structure in the FIG. 9 and 10 embodiment corresponding to that of the FIGS. ll through 6 embodiment is identified by the same reference numerals with the addition of a subscript b".
- orifice fitting 16b of FIGS. 9 and 10 is modified from that of the previous embodiment by the addition of a stationary adapter member 90 which is fixedly secured within the interior of fitting 16b in overlying relationship with the bottom end wall of the fitting.
- Adapter 90 is formed with a centrally located hub 92 through which a central bore 94 extends to serve as a bearing for a shaft 96 which forms a portion of the valve rotor of this embodiment.
- adapter member 90 For each group of discharge orifices 32b, adapter member 90 is formed with a housing portion 98 having an internal chamber 100 which opens radially at an inlet port 101 into bore 94 and which is in communication at its opposite end with an individual group of discharge orifices 32b.
- the valve rotor of the FIG. 9 and 10 embodiment consists of an upper wall 44b, similar in construction to the upper wall 44 of the FIG. 1 through 6 embodiment, and a centrally located shaft 96 which is fixedly secured to wall member 44b.
- Shaft 96 is rotatably received within bore 94 of adapter member 90 and is formed with an axially extending groove 102 which functions as the rotating valve port of the device.
- the angular extent of groove 42 about the rotor axis is 120.
- valve port l02b does not act directly upon each individual discharge orifice 32b, but instead controls the flow of water from the supply side to a relatively large chamber 100 which is commonly connected to all of the individual orifices 32b of a given group.
- the number of individual orifices in communication with the supply side of the rotating valve can vary from a minimum of an entire single group of orifices when only one inlet port 101 is exposed to valve port 102 to two entire groups or orifices when valve port 102 partially uncovers each of two adjacent inlet ports 101.
- Inlet ports 101 are all of like dimensions and are symmetrically disposed about the circumference of bore 94 on 120 centers. Thus, the total area of inlet port in communication with valve port 102 remains constant at all times to present a constant cross sectional flow area which eliminates a pulsation in the back pressure exerted on the supply by the nozzle. Although the total ultimate outlet area presented by discharge orifices 32b can vary, the resistance to flow imposed by the discharge orifices is modulated at the inlet port 101 to maintain the back pressure exerted by the nozzle substantially constant at all times.
- FIG. 9 and It does, however, modify the characteristics of the spray discharged by the nozzle as compared to that discharged by the embodiments of FIGS. ll through 6 and 7 and 8.
- each in dividual orifice 32 is either discharging water under full pressure or is not discharging water at all.
- the discharge pressure at each individual orifice 32b can vary in dependence upon the total area ofits associated inlet port 101 which is uncovered by valve port I02.
- water is initially discharged from the orifice in a substantially cylindrical slug having a diameter generally corresponding to that of the individual orifice and an axial length dependent upon the period of time over which the orifice is uncovered.
- this cylindrical slug of water moves away from the nozzle, air resistance tends to cause the slug to break up into individual droplets, the slug at first tending to try to assume a teardrop shape and at some point bursting or exploding into a group of individual droplets.
- the distance from the nozzle at which this explosion will occur is dependent to a large extent upon the initial supply pressure and the rate of rotation of the valve rotor.
- FIG. 9 and 10 embodiment tends to discharge a slug which almost immediately begins to assume a generally teardrop shape, water discharged during the middle of the discharge cycle being under higher pressure and thus tending to catch up with the initially discharged portions of the slug, while the decreasing discharge pressure at the end of the cycle causes the water to trail out.
- the explosion of the individual slugs discharged from the FIG. 9 and 10 form of nozzle tends to occur at relatively short distances from the nozzle, i.e., in the neighborhood of 6 inches under pressure and rotor speed conditions which in the FIG. 1 through 8 embodiments would occur at 12 to 18 inches from the nozzle.
