Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
A spray head assembly comprising a body, a moveable holder carried by said body, spray means in said movable holder for spraying fluid from said body, a passage defined in said body, said passage communicating with said spray means to deliver the fluid thereto which is to be sprayed, deflection means in and moveable with said moveable holder, said deflection means being normally moved to a first position between said spray means and said passage and out of the path of the fluid stream issuing from the spray means when the moveable holder is moved to a first position and said deflection means being moveable to a second position wherein said spray means is positioned between said deflection means and said passage when the moveable holder is moved to a second position, said deflection means being positioned in the path of the fluid stream issuing from the spray means when said moveable holder is in said second position whereby said deflection means is impinged by said fluid stream to diffuse the fluid stream.
Claim 2
Dependent Claim
173 words
A spray head assembly comprising a body, a moveable holder carried by said body, spray means in said movable holder for spraying fluid from said body, a passage defined in said body, said passage communicating with said spray means to deliver the fluid thereto which is to be sprayed, deflection means in and moveable with said moveable holder, said deflection means being normally moved to a first position between said spray means and said passage and out of the path of the fluid stream issuing from the spray means when the moveable holder is moved to a first position and said deflection means being moveable to a second position wherein said spray means is positioned between said deflection means and said passage when the moveable holder is moved to a second position, said deflection means being positioned in the path of the fluid stream issuing from the spray means when said moveable holder is in said second position whereby said deflection means is impinged by said fluid stream to diffuse the fluid stream.
Claim 3
Dependent Claim
22 words
The assembly of claim 1 wherein said moveable holder is rotatable and is rotated approximately 180* between said first and second positions.
Claim 4
Dependent Claim
13 words
The assembly of claim 1 wherein said deflection means comprises a vane means.
Claim 5
Dependent Claim
33 words
The assembly of claim 3 wherein said vane means is spiral in form and swirls the fluid stream issuing from the spray means when said moveable holder is moved to said second position.
Claim 6
Dependent Claim
33 words
The assembly of claim 1 wherein said deflection means comprises means for producing turbulence in the fluid stream issuing from said spray means when said moveable holder is moved to said second position.
Claim 7
Dependent Claim
12 words
The assembly of claim 1 wherein said deflection means comprises a pin.
Claim 8
Dependent Claim
57 words
The assembly of claim 1 wherein said deflection means comprises a first bore communicating with said spray means and a plurality of second bores communicating with said first bore the fluid stream issuing from said spray means entering said first bore and exiting from said second bores when said moveable holder is moved to said second position.
Claim 9
Dependent Claim
50 words
The assembly of claim 1 wherein said moveable holder defines a passage therethrough in communication with said fluid-delivering passage, said spray means being positioned in said holder passage, and plug means in said holder passage carrying and positioning said deflection means and maintaining said spray means in said holder passage.
Claim 10
Dependent Claim
74 words
The assembly of claim 1 wherein said moveable holder defines a passage therethrough in communication with said fluid delivering passage, said spray means being positioned in said holder passage, plug means in said holder passage, insert means in said holder passage between said spray means and said plug means, said insert means carrying and positioning said deflection means, and said plug means maintaining said spray means and said insert means in said holder passage.
Claim 11
Dependent Claim
31 words
The assembly of claim 1 wherein when said moveable holder is moved to said second position, the flow of fluid through said spray means is reversed for cleansing the spray means.
