Class Information
Number: 416/187
Name: Fluid reaction surfaces (i.e., impellers) > Rotor having flow confining or deflecting web, shroud or continuous passage > Radially extending web or end plate > Circumferentially and radially continuous web or end plate > Having opposed annular surface between adjacent blades > Angularly spaced, axially elongated blades (i.e., squirrel cage type)
Description: Apparatus in which the working member* has a dimension along the axis of rotation which is substantially greater than the dimensions along a radius (transverse to the axis of rotation) or across the member (thickness), the plurality of such members arranged and spaced around the annular surface, the member being of substantially constant radial extent along its length and supported between the two surfaces distally from the axis of rotation.
