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.
Claims10
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.
