Abstract
Abstract A spraying device includes a support arm mounted in a toilet bowl for pivoting between a retracted and an extended position at one of its ends, and carrying a spraying head at the other end. The spraying head has two compartments which are sealingly separated from one another, each of the compartments communicating with a different set of spraying apertures, one of the sets having a larger flow-through cross-sectional area than the other set. Separate conduits communicate a control valve to which a spraying liquid is delivered, with each of the compartments to issue through the two sets of apertures at different speeds in proportion to the different flow-through cross-sectional areas of the two sets. The control valve may be incorporated in the holder for the support arm, and the apertures of the two sets may aim in different directions, respectively. The compartment communicating with the set of larger total flow-through cross-sectional area may circumferentially surround the other compartment and its apertures may be inclined in the upward and frontward direction of the toilet bowl when the support arm is in its extended position in which the control valve is open.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
156 words
A spraying device, particularly for use in toilets, comprising a spraying head including external wall means bounding a chamber and having at least one first and one second spraying aperture communicating said chamber with the exterior of said spraying head, and internal wall means subdividing said chamber into at least two compartments sealed with respect to one another and communicating with said first and said second spraying aperture, respectively; means for admitting spraying liquid into each of said compartments to issue therefrom through the respective spraying aperture; and means mounting said spraying head in a toilet bowl movable relative to the latter and operative for moving said spraying head between a first position in which the spraying liquid is admitted into one of said compartments to issue therefrom through said first aperture and a second position in which the spraying liquid is admitted into at least the other compartment to issue therefrom through said second aperture.
Claim 2
Dependent Claim
156 words
A spraying device, particularly for use in toilets, comprising a spraying head including external wall means bounding a chamber and having at least one first and one second spraying aperture communicating said chamber with the exterior of said spraying head, and internal wall means subdividing said chamber into at least two compartments sealed with respect to one another and communicating with said first and said second spraying aperture, respectively; means for admitting spraying liquid into each of said compartments to issue therefrom through the respective spraying aperture; and means mounting said spraying head in a toilet bowl movable relative to the latter and operative for moving said spraying head between a first position in which the spraying liquid is admitted into one of said compartments to issue therefrom through said first aperture and a second position in which the spraying liquid is admitted into at least the other compartment to issue therefrom through said second aperture.
Claim 3
Dependent Claim
28 words
A spraying device as defined in claim 1, wherein said external wall means has a plurality of additional first and second spraying apertures communicating with said compartments, respectively.
Claim 4
Dependent Claim
50 words
A spraying device as defined in claim 1, wherein said mounting means are operative for admitting the spraying liquid in said second position of said spraying head additionally into said one compartment so that the spraying liquid in said second position issues both through said first and said second apertures.
Claim 5
Dependent Claim
71 words
A spraying device as defined in claim 2, wherein said first spraying apertures have a combined flow-through cross-sectional area which exceeds the combined flow-through cross-sectional area of said second spraying apertures so that the spraying liquid issuing through said first spraying apertures has a pressure and speed less than those of the spraying liquid issuing from said second spraying apertures and thereby performs a more gentle cleaning action than the latter.
Claim 6
Dependent Claim
29 words
A spraying device as defined in claim 4 wherein at least some of said first spraying apertures are inclined in the frontward direction of the toilet bowl and upwardly.
Claim 7
Dependent Claim
18 words
A spraying device as defined in claim 2, wherein one of said compartments circumferentially surrounds the other compartment.
Claim 8
Dependent Claim
28 words
A spraying device as defined in claim 6, wherein said one compartment communicates with said first spraying apertures, and the other compartment communicates with said second spraying apertures.
Claim 9
Dependent Claim
60 words
A spraying device as defined in claim 1, wherein said means mounting said spraying head in a toilet bowl include a support arm; and wherein said admitting means includes a main conduit and at least two branch conduits each communicating said main conduit with one of said compartments, said branch conduits being supported by and extending along said support arm.
Claim 10
Dependent Claim
36 words
A spraying device as defined in claim 8; and further comprising valve means interposed between said main conduit and said branch conduits and operative for controlling the admission of the spraying liquid into said branch conduits.
Claim 11
Dependent Claim
63 words
A spraying device as defined in claim 9, wherein said mounting means further includes at least one pivot mounting said support arm at the toilet bowl for pivoting between a retracted inoperative, and an extended operative, positions; and wherein said valve means is connected to said support arm and operative for closing in said retracted position and for opening in said extended position.
Claim 12
Dependent Claim
35 words
A spraying device as defined in claim 10, wherein said mounting means further includes a holder for said pivot; and wherein said valve is incorporated in said holder and is partly formed by the same.
Claim 13
Dependent Claim
22 words
A spraying device as defined in claim 4, wherein said first spraying apertures extend in different directions from said first spraying apertures.
