Abstract
A nozzle for use in cleaning applications is provided. The nozzle has a rotatably supported nozzle body, on which one or more nozzle orifices are provided. The nozzle housing itself serves as the rotary drive, which is carried along by a fluid led into the housing with torque. In order to stabilize the drive action, at least one braking device is provided on the nozzle which generates a braking torque by fluid action, preferably through the recoil on a nozzle opening.
Claims27
A nozzle assembly for discharging a fluid for cleaning containers, comprising:
- a rotatable nozzle housing having a cylindrical chamber,
- a first fluid drive for applying a first torque on the nozzle housing and thereby rotating the nozzle housing,
- said nozzle housing being formed with a braking fluid discharge opening having an orientation that opens outwardly of the said cylindrical housing chamber in the direction of rotation of the nozzle housing for directing liquid outwardly of said housing to retard the rotation of said nozzle housing as an incident to the direction of pressurized fluid through said nozzle housing, and
- said nozzle housing being formed with at least one spray discharge orifice of a first form that opens outwardly of said cylindrical housing chamber with an orientation different from said breaking fluid discharge opening substantially in a radial direction for discharging a predetermined fluid spray from said rotatable housing in a radial direction as an incident to the direction of pressurized fluid through said housing and rotation of said housing, and
- said nozzle housing being formed with a braking fluid discharge opening having an axis that does not intersect the axis of rotation of the nozzle housing and which is oriented such that the braking fluid discharge opening opens outwardly of the said cylinderical housing chamber in the direction of circumferential rotation of the nozzle housing for directing liquid outwardly of said housing to retard the rotation of said nozzle housing as an incident to the direction of pressurized fluid through said nozzle housing.
2 more elements
A nozzle assembly for discharging a fluid for cleaning containers, comprising:
- a rotatable nozzle housing having a nozzle orifice formed therein for discharging fluid from the nozzle housing, said nozzle housing having a cylindrical shape and enclosing a substantially symmetrical interior space which is transversed by the fluid,
- a first fluid drive that includes a torque generating device for imparting torque to fluid and for applying a first torque on the nozzle housing and thereby rotating the nozzle housing, and
- a braking device comprising a second fluid drive that is separate from the first fluid drive and which is arranged to retard the rotation of the nozzle housing, and
- said torque-generating device including a cylindrical section which is part of a bearing element arranged to rotatably support the nozzle housing, said cylindrical section having a mantle surface as well as an annular face surface facing in a flow direction, an entry opening in the form of a groove which is open to the mantle surface and the face surface, said groove extending so as to be inclined to the axial direction, and a small gap for bearing of the nozzle housing established between the mantle surface and the nozzle housing and arranged concentrically thereto.

A nozzle assembly for discharging a fluid for cleaning containers, comprising:
- a rotatable nozzle housing having a nozzle orifice formed therein for discharging fluid from the nozzle housing,
- a first fluid drive for applying a first torque on the nozzle body and thereby rotating the nozzle housing,
- a braking device comprising a second fluid drive that is separate from the first fluid drive and which is arranged to retard the rotation of the nozzle housing, said braking device including a breaking discharge opening provided in the housing from which discharging fluid brings about a reaction force, said breaking discharge opening being bounded circumferentially by a first wall aligned substantially axially that is inclined outward in a turning direction and upon which the discharging fluid exerts a recoil force which retards the nozzle housing in its rotation movement and a second wall approximately parallel of the first wall and ahead of the first wall in the direction of rotation of the nozzle housing.
A nozzle for discharging a fluid for the cleaning of containers comprising,
- a rotatable nozzle body including a housing having a nozzle orifice formed therein for discharging fluid from the nozzle,
- a fluid drive including a rotor formed by the housing of the nozzle body which is driven by the action of the fluid, a torque-generating device including a cylindrical section which is part of a bearing element arranged to rotatably support the nozzle body, said cylindrical section having a mantle surface as well as an annular face surface facing in a flow direction, an entry opening in the form of a groove which is open to the mantle surface and the face surface, said groove extending so as to be inclined to the axial direction, and a small gap for bearing of the housing being established between the mantle surface and the housing of the nozzle body and arranged concentrically thereto.
