Definitions

  • ABSTRACT A combination spray and aerator device is disclosed for attachment to a faucet and includes a deflector selectively movable between a stream deflecting position in which the water is caused to flow through an aerator assembly and a non-deflecting position in which the water flows unobstructed to a spray skirt.
  • the de' flector may comprise a sleeve axially displaceable between the deflecting and non-deflecting positions.
  • a filtering arrangement including a strainer cup positioned within a swivel ball at the upper extremity of the device prevents particles larger than a predetermined size from passing through the device.
  • the area of the flow passage is made progressively larger from the inlet to the discharge region of the device.
  • the present invention relates generally to fluid devices having plural flow paths and particularly to sprayaerators adapted for attachment to water faucets or the like.
  • the deflector By breaking up the water in the deflecting position, the deflector contributes to the formation of a high quality aerated stream, that is, one which is full and has a uniform, circular shape and is devoid of flutter, spin or wild spots.
  • the formation of such a stream is further enhanced in devices of the present invention by progressivly increasing the flow passage area from inlet to discharge. The flow velocity is thereby progressively reduced and the stream broken up and widened during its passage through the device.
  • One specific, exemplary form of the invention includes a central post adapted to be attached to a faucet or similar water source and having an aerator assembly attached to its lower end.
  • a bore extends from the upper end of the post to a plurality of circumferentially-spaced discharge ports in the lower portion of the post.
  • a sleeve, disposed about the post in slidable relation thereto, is axially displaceable between a first or upper position in which the water passes unobstructed from the discharge ports of the post radially outward to a spray skirt and a second or lower position in which the water issuing from the discharge ports is deflected through about to flow downwardly through the aerator assembly.
  • Water from the post discharge ports is constrained to flow outwardly in the form of a uniform, radial sheet between a pair of spaced, parallel surfaces defined by the post and a flow directing element carried by the post.
  • the spray skirt surrounds the aerator assembly and sleeve and is coupled to the post for rotation thereabout.
  • the spray skirt has an internal surface for receiving the water from the discharge ports when the sleeve is in the upper position.
  • the internal surface defines spray forming and directing flutes shaped and oriented to establish the above-mentioned predetermined spray pattern.
  • the sleeve has helical cam surfaces engaged by pins secured to the spray skirt and rotation of the spray skirt about the post in one direction causes the sleeve to move to the above-mentioned upper, non-deflecting position while rotation of the skirt in the other direction moves the sleeve to the lower, stream deflecting position.
  • the upper extremity of the post may typically include a swivel ball retained by a threaded nut member adapted to be connected to the faucet.
  • the device may thereby be swivedled, in well known fashion, to various angular positions relative to the faucet.
  • a particle filtering arrangement including a strainer cup nested within the upper extremity of the post bore.
  • the upper edge of the strainer cup has a diameter slightly smaller than the diameter of the upper extremity of the post bore to define a small annular inlet opening limiting the size of particles that can enter the bore. Most particles that are unable to enter the narrow inlet opening are flushed to one side or-the other of the opening, that is, into the strainer cup or into the interior of the nut member. Any particles that become lodged in the inlet are pushed into the strainer cup by the action of a wiper ring carried by the threaded nut member, the ring having an inner edge in engagement with the swivel ball.
  • a high quality, aerated stream is in part achieved by progressively increasing the flow passage areas downstream of the annular inlet opening.
  • the cross-sectional area of the post bore is considerably larger than the area of the inlet opening.
  • the radial sheet of water issuing from the post discharge ports (which in total area are large enough so as not to introduce any flow restrictions) has a flow area larger than the post bore. Still larger is the flow passage bounded by the sleeve (in its lower position) and forming the entry to the aerator assembly.
  • the aerator assembly which includes a series of spaced screens, further breaks up and slows the water and tends to even out the stream.
  • a washer underneath the aerator assembly retains the assembly on the post and further functions to additionally spread the stream and dampen its velocity.
  • Cleaning of devices of the present invention is accomplished simply by removing the device from the faucet and rinsing the nut member and strainer cup. There is little or no tendency for particles to accumulate at any point downstream of the inlet opening, such particles as are able to pass through the inlet opening being of such size that they are flushed through the entire device.
  • FIG. 1 is an exploded, perspective view of a combination spray and aerator device in accordance with one form of the invention
  • FIG. 2 is an axial cross-section of the device of FIG. 1 showing the device in the spray position;
  • FIG. 3 is an axial cross-section of the device of FIG. 1 in which the device is shown in the aerator position;
  • FIG. 4 is a transverse cross-section of the device in the aerator position as shown in FIG. 3, the section being taken along the plane 4-4;
  • FIG. 5 is an axial cross-section of a portion of a sprayaerator device comprising an alternative form of the present invention
  • FIG. 6 is an axial cross-section of a spray-aerator device in accordance with another alternative form of the present invention.
  • FIG. 7 is a transverse cross-section of the device of FIG. 6 taken along the plane 7-7.
  • the spray-aerator has a central, longitudinal axis 10 and includes a mounting nut 12 having an internal thread 14 for attachment, in conventional fashion, directly to a faucet (not shown) or to an adapter (not shown) which in turn is connected to the faucet.
  • the nut 12 includes an annular recess 16 and a shoulder 18, the recess 16 receiving a sealing O-ring 20 and the shoulder 18' supporting a plastic wiper ring 22.
  • a flat rubber gasket 28 rests on the wiper ring 22.
  • a central post 32 Depending from the mounting nut 12 is a central post 32 having a spherical swivel head 34 nested within the nut 12 so that the spray aerator device may he swiveled relative to the faucet to direct the discharge stream as desired.
  • the inner edge 26 of the lip 24 maintains contact with the outer surface of the swivel head 34 as the post is swiveled.
  • the post 32 has a generally cylindricalcentral section including a pair of axially spaced grooves 36 and 38 formed in the outer surface thereof.
  • the groove 36 receives the inner ends of a pair of pins 40 whose function will be described below; the groove 38 retains a sealing O-ring 42.
  • Projecting from the upper part of the central section of the post 32 and integral therewith is an axially oriented key 44.
  • a longitudinal bore 46 Extending along the major portion of the length of the post concentric of the axis 10 is a longitudinal bore 46. At its upper end, within the swivel head 34, the bore 46 is enlarged to form a receptacle 48 having an upper edge 50. Projecting inwardly from the wall of the receptacle 46 are four narrow, axially oriented ribs 52 upon which is seated a strainer cup 54. The cup 54 has an upper edge 56 defining together with the edge 50 a narrow, annular inlet opening 58. A rod 60 projects upwardly from the bottom of the cup 54 and serves as a handle to facilitate removal and re-insertion of the cup.
  • central bore 46 Near the lower end of the central bore 46 are several circumferentially spaced discharge ports 64. In the embodiment under consideration four such ports are shown although more or less than this number may be employed.
  • the ports 64 are equally spaced about the central axis 10 and separated by struts 66 having a triangular cross section as best shown in FIG. 4.
  • the lower extremity of the post consists of a generally cylindrical, bifurcated tip 70 having a circumferential groove 72.
  • the tip 70 may be compressed to bring the lower edges of the tip halves together; when released, the tip 70 springs back to the original configuration shown in the drawings.
  • the sleeve 76 Surrounding the central section of the post 32 in slidable relation thereto is a sleeve 76.
  • the sleeve 76 may be made of Delrin and has an axially directed keyway 78 for receiving the post key 44 and the sleeve is thereby restricted to axial, that is, vertical movement relative to the post.
  • the sleeve 76 further has a pair of diametrically opposed, symmetrical slots 80 oriented in skew relation to the central axis 10.
  • the slots 80 may be helically oriented with respect to the axis 10.
  • the pins 40 extend through the slots 80.
  • a spray skirt 84 positioned concentric of the axis 10, surrounds the sleeve 76 and is freely movable relative to the sleeve.
  • the skirt 84 comprises an upper cylindrical portion 86 having an internal bore receiving the sleeve 76 and a lower, enlarged portion 88 defining a flared, internal surface of revolution 90 having flutes 92 for directing the discharging water in the desired spray pattern.
  • the design of the flutes to achieve a particular spray pattern is well known in the art; in the example shown there are 24 equally spaced flutes whose exit surfaces are angularly oriented relative to the central axis 10 so as to provide a spray pattern consisting of four streams parallel to the axis 10, eight streams diverging from the axis at an angle of 5 and 12 streams diverging from the axis at 10.
  • the skirt 84 may be made of clear acrylic plastic.
  • the cylincrical portion 86 of the spray skirt 84 has a pair of diametrically opposed holes retaining the outer portions of the pins 40.
  • the outer ends of the pins lie flush with the outer surface of the cylindrical portion 86 of the skirt 84.
  • the pins 40 and holes in which they are received may be dimensioned for a sliding tit and held in place by an ornamental sheet metal ring 94 bonded about the upper portion of the skirt 84.
  • the pins 40 and holes in which they are received may be dimensioned for an interference or force fit so that once installed the pins are not readily removable; alternatively, the pins 40 may be dimensioned for a sliding fit and held in place by an ornamental sheet metal ring 94 bonded about the upper portion of the skirt 84.
  • a flow control element 96 of Delrin is attached to the lower part of the post 32 for shaping and directing the flow of water issuing from the post discharge ports 64.
  • the control element 96 has an upper, planar surface 98 which, in cooperation with an adjacent, parallel surface 100 on the post 32, confines the water discharging from the ports 64 to flow outwardly toward the spray skirt 84 as a uniform, radial sheet.
  • An aerator assembly 104 carried by the tip 70 of the post 32, comprises a ring-like, metallic housing 166 containing a series of brass screens 108 separated axially by annular, plastic spacers 110.
  • the screens 168 of which there may be three in a typical installation, have central apertures for receiving the tip 70 and the aerator assembly 104 is retained by a brass washer 112 snapped into the groove 72.
  • the screens may have various mesh sizes. In one practical example, each screen is made of 24-mesh stock.
  • the lower portion of the spray skirt 84 substantially completely surrounds the aerator assembly 104 and the upper surface 11 of the assembly 104 is disposed a small distance below the surface 98 of the control element 96.
  • a high quality aerated stream is in part obtained by observing certain area relationships along the flow path.
  • the area of the flow passage becomes progressively larger along the flow path thereby progressively reducing the stream velocity and breaking up the flow stream.
  • the area A of the annular inlet opening 58 is 0.0177 sq. in.
  • the cross-section area B of the post bore 46 is 0.0314 sq. in.
  • the flow area C of the space between the surfaces 98 and 100 is approximately 0.0365 sq. in.
  • the annular area D defined by the outer edge of the flow control element 96 and the inner wall of the sleeve 76 is 0.041 sq. in.
  • the total area of the ports 64 is large enough to preclude any restrictions from being introduced thereby and as a result the water flows outwardly between the surfaces 98 and 100 as an essentially solid sheet that is substantially uniform about the axis 10.
  • the quality of the aerated stream is further enhanced by the presence of the deflecting sleeve 76 against which the water breaks up and is provided with an inwardly directed component.
  • the screens 108 further break up and slow the water and even out the flow.
  • the washer 112 further dampens, that is, reduces the water velocity and also helps spread or fatten" the stream thereby additionally compensating for the inward component introduced upon deflection from the sleeve 76.
  • the size of the washer 112 determines its effectiveness for this purpose and according to the example under consideration, the washer has a diameter of five/sixteenth inch.
  • Devices according to the invention also incorporate a simple yet effective filtering arrangement.
  • the narrow, annular inlet opening 58 is dimensioned to prevent particles above a minimum acceptable size from entering the device.
  • Cleaning of the device of the present invention is accomplished simply be removing the device from the faucet and rinsing the removable strainer cup 54 and the mounting nut 12.
  • FIG. 5 there is shown an alternative form of the present invention including a central post identical to the post 32 already described except that it has a pin-receiving upper groove 122 that is enlarged in the axial direction.
  • the device includes a spray skirt H24 and sleeve 126 bonded together or otherwise joined so that these elements move as a single unit.
  • Opposed pins 128 are secured to the skirt and sleeve and project into the groove 122. Because the axial length of the groove T22 is considerably larger than the diameter of the pins 128, the skirt and sleeve combination may be displaced vertically to the extent permitted by the groove to move the lower portion of the sleeve into, or out of, the water deflecting position.
  • FIG. 5 does not incorporate the cam action furnished by the helical slots in the device of FIGS. 1-4; nevertheless, because there is little resistance to displacement of the sleeve, the force required to change the position of the sleeve is minimal.
  • FIGS. 6 and 7 show another version of the invention including a mounting nut 34, a central post 136 having a swivel head 13% coupled to the nut 134, a sleeve 140, a spray skirt 142 and an aerator assembly 144. All of these elements cooperate in the manners already described, and although this version does not include the strainer cup feature of the previously discussed forms of the invention, it will be understood that such feature may be utilized herein.
  • the post 136 includes a Delrin flow plug 146 having a series of axially-oriented flanges 148 whose outer extremities 154 are threadedly received within an expanded portion of the post bore 152. Although four flanges 148 are shown, it will be understood that more or less may be utilized.
  • the plug 146 also includes a radial shoulder 154 having an upper surface 156 that cooperates with a radial surface 158 on the post 136 to constrain the water discharging from between the flanges 148 to flow outwardly as a relatively thin radial sheet. To facilitate the early formation of such water sheet, the axial flanges 148 may be undercut as shown at 160.
  • the lower extremity 162 of the flow plug 146 is bifurcated and grooved as described in connection with the tip 70 of the device of FIGS. 1-4 and in like fashion supports the aerator assembly 144 with a brass retaining and flow spreading washer 164.
