Best Mode For Carryino Out The Invention Referring more particularly to the drawings, Figs. 1-9 show the various parts of the present invention. Referring to Fig. 1, the shower head 10 according to the 1o present invention includes an outer shell 12, that is threadingly engaged to a valve body 14. In the upper part of the shell is mounted a ball joint 24 maintained within the shell by a split ring 26 and sealed by an O-ring 28. Within the ball joint is located a flow control ring 30, a flow control restrictor 32 and a screen washer 34.
The valve body 14 has a generally cylindrical cavity forming an inlet port.
The upper end of the cavity, relative to the orientation shown in Fig.' 1, is of a large cross-sectional area and mates with the ball joint 24. Disposed at the lower end of the cavity is a downstream opening 56, which is of a smaller area. The downstream opening 56 functions as the inlet port relative to the outlet ports to be described herein. The inlet port is shown more fully in Fig. 6, which is a top view of the 2 o valve body 14.
The downstream opening 56 communicates with a passageway 54, which is also shown in cross-section in Fig. 6, as well as end-wise in Fig. 4. The passageway has at least two outlet ports 58 and 60, as shown in. Figs. l and 5. For purposes of this discussion, the ports 58 and 60 will be respectively referred to as a first outlet port (58) and a second outlet port (60). The first outlet port 58 ' communicates with the face plate 18 of the shower head. The face plate 18 is retained against the valve body 14 by a retainer ring 20 which, via threads 52, engages the valve body. A series of O-rings 28 mounted at various locations around the retainer ring and the face maintain sealing engagement between the parts.
The face plate 28 has two portions. The first portion, as shown most clearly in Figs. 8 and 9, consists of a series of angled bores 62 which communicate with the first opening 58. These bores produced a constant spray. The second portion of the face plate 28 consists of a series of bores 64 grouped pair-wise around the W~ 92/02305 PCd'/LJ~9l/056 9 ~'Y
U~~l~ ~
a;~
periphery of the face plate, as shown in Figs. 8 and 9. These holes receive water through two channels, 66 and 68, which communicate with' an annular cavity 76, in the rear side of the face plate, as shown in Figs.
1 and 8. This annular cavity 76 is in fluid communication with the second outlet ' port 60. Disposed between the face plate 28 and the valve body I4 is a rotor 22, which is shown in more detail in Fig. 10. The rotor has a rotor base 48 with a series of blades 50 spaced about the periphery. The rotor is oriented such that water from the channels 66 and 68 tangentially impacts the rotor blades 50, thereby imparting rotation. The spinning rotor thus breaks the flow of water from the annular cavity 76 to the outlet bores to 64, thereby producing a pulsating effect.
Operation of the present invention is controlled by a pushrod 36 disposed within the passageway 54 in the valve body 14. The pushrod 36 is an elongated member having left and right cam following surfaces 44, 46. In the middle portion of the pushrod are two areas of reduced diameter 40 .
and 42 to allow the flow of water. Also located on the pushrod 36 are. a series of O-ring channels 38a, b, and c which have mounted thereupon another series of O-rings 28. The left O-ring channel 38a and the right O-ring channel 38c are used to establish a fluid seal fox the pushrod within the passageway 54. The central 0-ring cavity 38b with the accompanying O-ring communicates with the downstream inlet port 56 to direct 2o water from the inlet port 56 through the first and second outlet pons 58 and 60 as controlled by the user. When the pushrod is in the orientation shown in Fig. l, all of the water flows from the downstream inlet 56 to the first outlet 58 and thereafter through the series of angled bores 62 to produce a continuous spray effect.
Conversely, if the pushrod 36 is moved to the right side of the downstream opening 56, the first outlet passage S8 would be sealed and the second outlet passage 60 would be open, thereby producing the pulsating "jet"
effect described hereinabove.
Alternatively, there can be a mixture of water flowing between the first and second outlet ports 58 and 60 if the middle O-:ring channel 38b of the pushrod 36 was orientated somewhere between the full left position as shown in Fig. 1 and the full right position as described.
Control of the location of the pushrod is done by a cam ring 16 which is shown in more detail in Fig. 7. Cam ring I6 is mounted in the shower head by the retainer ring 20. It is free to rotate under control of the user. As shown in Fig. 7, 5 ~ ~ ~ y ~ f, ~ P~,'1'/US91/05639 ~a~ .~, r .y~
the cam ring 16 has a series of outer teeth 74 which arewsed by the user to turn the cam ring. Disposed within the cam ring 16 are two cam surfaces 70 and 72 which engage the left and right cam follower surfaces 44 and 46 on the pushrod 36.
As can be seen, the present invention represents a much simpler valve 5 mechanism that requires few parts and yet which can be made to perform all the necessary functions for providing various spray effects. It also requires much fewer parts to orient the user's force in the manner necessary for proper operation.
In the foregoing description of the present invention, a preferred embodiment of the invention has been disclosed. It is to be understood that other mechanical and design variations are within the scope of the present invention. For example, the .
present invention could be easily adapted for a hand-held shower head.
Furthermore, a series of pushrods or a pushrod with additional flow control surfaces could be used to provide a series of different spray effects. Accordingly, the present invention is not limited to the particular arrangement which has been .15 illustrated and described herein.
