ABSTRACT:
A rotational atomizer turbine of the present invention is designed to drive a bell-shaped disk in a rotational atomizer for a coating unit. The rotational atomizer turbine includes a housing, a rotatable turbine wheel with several turbine blades connected to a shaft and rotatably disposed in the housing. A plurality of nozzles are defined in the housing and are positioned relative the turbine wheel to drive fluid, i.e. gas onto the turbine blades. An intermediate chamber formed in the housing is fluidly communicated with and connected to the nozzles to hold gas therein. The intermediate chamber has a first inlet to supply gas. At least a second inlet is defined in the intermediate chamber for delivering gas into the intermediate chamber thereby increasing amount of gas therein to multiply a rotational speed of the rotatable turbine wheel as increased amount of gas is introduced to the turbine blades.
