Rotary atomizer

DETAILED DESCRIPTION It is therefore an object to provide a rotary atomizer which can eliminate dried paint build-up on its front rotating surface.
It is further an object of this invention to provide a rotary atomizer which is light, compact and easily manufactured as well as easily serviced.
It is further an object of this invention to provide a rotary atomizer which is highly resistant to paint build-up on its exterior surfaces.
A rotary atomizer cup is provided which has the main portion of the cup or bell with a large central bore in which is suspended a distributor assembly.
A combination of the cup and distributor assembly forms therebehind a feed chamber which primarily feeds paint through an annular gap between the distributor assembly and the main cup to the front discharge surface of the cup.
The distributor assembly has located in the middle thereof a small diffuser which allows a very small proportion to the total paint fed through the center feed tube to pass to the middle of the front of the distributor.
By precisely sizing the passages, a small cup-like area on the front of the distributor/diffuser assembly may be kept full of liquid paint, and that paint then flows off over the front surface of the distributor such that all of the front surface of any portion of the bell can be covered with wet paint.
By suspending the distributor assembly on three small pins, total coverage of the front discharge surface of the cup with paint will be very uniform thereby providing superior atomization and finishing.
This construction also makes for easy and quick flushing during color changing.
A combination center feed tube and stationary shaft extends forwardly from the housing base and is held in place by means of three set screws which engage a groove in the stationary shaft.
A rotating shaft with a set of bearings is located over the stationary center shaft and has affixed to the front end thereof the rotary cup or bell atomizing element.
Use of this construction allows the turbine assembly to be easily removed and serviced without the need to disconnect any hoses or the like thus minimizing downtime
