Aerial centrifugal impeller

Abstract

An impeller includes a lower dome having a curved outer surface. Disposed on the curved outer surface of the lower dome is a plurality of blade. The blades are formed to define an inner curved surface and an outer curved surface, each blade having a leading edge and a terminal edge. The impeller comprises an an upper dome, the inner surface of which is mounted on the outer curved surfaces of the blades; The upper dome has an annular opening formed therethrough. The annular opening of the upper dome is coaxially positioned with an annular bore in the lower dome. The annular bore is sized for receiving a rotary shaft. A plurality of flow compartments or chambers are defined in the conjunction of the lower dome, the plurality of blades, and the upper dome. An embodiment of the impeller comprises a rotary shaft in connection between at least the annular bore of the lower dome on one end and a motor on the other.

What is claimed is: 
     
         1 . An impeller comprising
 a. a lower dome having a curved outer surface wherein an annular bore is formed therethrough;   b. a plurality of blades circumferentially disposed on said curved outer surface of said lower dome, wherein each of said blades has an inner curved surface, an outer curved surface, a leading edge and a terminal edge;   c. an upper dome having an annular opening formed therethrough, said upper dome having an interior surface mounted on the outer curved surfaces of said blades;   
       wherein a plurality of flow chambers are defined in the conjunction of said lower dome, said plurality of blades, and said upper dome. 
     
     
         2 . The impeller of  claim 1  further comprising a shaft positioned in at least said annular bore of said lower dome. 
     
     
         3 . The impeller of  claim 2  further comprising a motor operationally connected to a motor.
