Abstract
Abstract A spraying device is described comprising a nozzle formed with an outlet orifice through which the fluid issues in the form of a jet, and a cup-shaped member having a thin wall defining an open end of slightly larger diameter than the outlet orifice. The cup-shaped member is floatingly mounted for lateral and axial movement with respect to the nozzle orifice such that the jet issuing therefrom always impinges the cup-shaped member within its open end. The device further includes limiting means limiting the floating movement of the cup-shaped member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
177 words
A spraying device comprising a nozzle formed with an outlet orifice through which the fluid issues in the form of a jet, a cup-shaped member having an open end supported close to and in alignment with said orifice so as to be impinged by the jet issuing therefrom, said cup-shaped member being floatingly mounted with respect to the nozzle so as to be movable both in a lateral direction with respect to said orifice and in an axial direction towards and away from said orifice, and limiting means limiting the floating movements of the cup-shaped member with respect to the nozzle orifice, the open end of the cup-shaped member facing the orifice being defined by a thin, substantially cylindrical wall whose thickness is a small fraction of the diameter of its open end, the inner diameter of the cup-shaped member being slightly larger than the sum of the outlet orifice diameter and the maximum lateral movement permitted by the limiting means, the surface of the nozzle facing the cup-shaped member around the nozzle orifice being substantially flat.
Claim 2
Dependent Claim
177 words
A spraying device comprising a nozzle formed with an outlet orifice through which the fluid issues in the form of a jet, a cup-shaped member having an open end supported close to and in alignment with said orifice so as to be impinged by the jet issuing therefrom, said cup-shaped member being floatingly mounted with respect to the nozzle so as to be movable both in a lateral direction with respect to said orifice and in an axial direction towards and away from said orifice, and limiting means limiting the floating movements of the cup-shaped member with respect to the nozzle orifice, the open end of the cup-shaped member facing the orifice being defined by a thin, substantially cylindrical wall whose thickness is a small fraction of the diameter of its open end, the inner diameter of the cup-shaped member being slightly larger than the sum of the outlet orifice diameter and the maximum lateral movement permitted by the limiting means, the surface of the nozzle facing the cup-shaped member around the nozzle orifice being substantially flat.
Claim 3
Dependent Claim
23 words
The device according to claim 1, wherein the depth of the cup-shaped member is at least one-half the diameter of its open end.
Claim 4
Dependent Claim
22 words
The device according to claim 1, wherein the outer rim of the cup-shaped member facing the orifice has a relatively sharp edge.
Claim 5
Dependent Claim
28 words
The device according to claim 1, wherein said cup-shaped member is biased by its own weight to close the nozzle orifice upon the termination of the jet therefrom.
Claim 6
Dependent Claim
35 words
The device according to claim 4, wherein the outward movement of the cup-shaped member is limited by said limiting means to a distance less than the diameter of the open end of the cup-shaped member.
Claim 7
Dependent Claim
36 words
The device according to claim 5, wherein the lateral movement of the cup-shaped member is limited by said limiting means to a distance less than one-half the diameter of the open end of the cup-shaped member.
Claim 8
Dependent Claim
73 words
The device according to claim 1, wherein the limiting means comprises a rod of greater length, and of smaller diameter, than the nozzle orifice and passing therethrough, the outer end of the rod being attached to the center of the bottom wall of the cup-shaped member, and the inner end of the rod including a stop limiting the outward movement of the rod and the cup-shaped member with respect to the nozzle orifice.
Claim 9
Dependent Claim
65 words
The device according to claim 1, wherein the bottom wall of the cup-shaped member is formed with a recess in its outer face, and wherein said limiting means includes a U-shaped rod having two legs attached to the nozzle and carrying a second rod at its center of smaller cross-sectional area than, and seatable within, said recess in the bottom wall of the cup-shaped member.
Claim 10
Dependent Claim
56 words
The device according to claim 1, wherein said cup-shaped member is carried by a rod passing through said nozzle orifice, and is constituted of an enlarged end of said rod and a flexible plastic sleeve received thereover such that one end of the sleeve projects below the enclosed end of the rod facing the nozzle orifice.
Claim 11
Dependent Claim
33 words
The device according to claim 9, wherein said flexible plastic sleeve is frictionally received on said enlarged rod end, and is removable therefrom so as to convert the device to a misting device.
