Abstract
In a rotary atomizer (10) including a rotating bell (92) secured to a rotating shaft (20a) of an air motor (20) held in an atomizer body, the rotating bell having a plurality of orifices (92a) for supplying paint to an object to be painted, the rotating bell being rotated to spray the paint toward the object to be painted, the rotary atomizer comprises a paint passage (102a) with a paint port (112c) at an end thereof fluidly communicating with the orifices of the rotating bell, and a water passage (108) arranged outside of the paint passage and having a water port at an end of the water passage leading to the orifices of the rotating bell. A needle (94) for opening and closing the paint port may be provided.
Claims20
A rotary atomizer, comprising:
- a rotary bell secured to a rotary shaft of an air motor held in an atomizer body, the rotary bell defining a plurality of orifices for dispensing a paint toward an object to be painted, wherein the rotary bell is configured to rotate to atomize the paint so as to spray the paint toward the object to be painted;
- a paint passage having a paint port, at a distal end thereof, fluidly communicating with the orifices of the rotary bell;
- a water passage, disposed outside of the paint passage, having a water port, at a distal end thereof, fluidly communicating with the orifices of the rotary bell;
- a water supply coupling coupled to the water passage and configured to supply water to the water passage, wherein the water supply coupling comprises an opening configured to fluidly couple to a water source;
- and
- the plurality of orifices are configured to dispense the paint and water simultaneously.
A system, comprising:
- a rotary atomizer, comprising:
- a rotary bell coupled to a rotary shaft of an air motor disposed in an atomizer body of the rotary atomizer, wherein the rotary bell comprises a plurality of orifices configured to dispense paint toward an object to be painted, wherein the rotary bell is configured to rotate to atomize the paint so as to spray the paint toward the object;
- a paint passage comprising a paint port disposed at a paint passage distal end, wherein the paint passage is fluidly coupled to the plurality of orifices;
- a water passage disposed outside of the paint passage and comprising a water port disposed at a water passage distal end, wherein the water passage is fluidly coupled to the plurality of orifices, and the plurality of orifices are configured to dispense the paint and water simultaneously;
- and
- a water supply coupling coupled to the water passage and configured to supply water to the water passage, wherein the water supply coupling comprises an opening configured to fluidly couple to a water source.
A system, comprising:
- a rotary atomizer, comprising:
- a rotary bell coupled to a rotary shaft of an air motor disposed in an atomizer body of the rotary atomizer, wherein the rotary bell comprises a plurality of orifices configured to dispense paint toward an object to be painted, and the rotary bell is configured to rotate to atomize the paint so as to spray the paint toward the object;
- a paint passage comprising a paint port disposed at a paint passage distal end, wherein the paint passage is fluidly coupled to the plurality of orifices, and the paint passage comprises a paint circular cross-section about a longitudinal axis of the rotary shaft;
- a water passage disposed outside of the paint passage and comprising a water port disposed at a water passage distal end, wherein the water passage is fluidly coupled to the plurality of orifices, the water passage comprises a water circular cross-section concentric with the paint circular cross-section, and the plurality of orifices are configured to dispense the paint and water simultaneously;
- and
- a water supply coupling coupled to the water passage and configured to supply water to the water passage, wherein the water supply coupling comprises an opening configured to fluidly couple to a water source.
