Class Information
Number: 415/219.1
Name: Rotary kinetic fluid motors or pumps > Working fluid passage or distributing means associated with runner (e.g., casing, etc.) > Casing with axial, conical flow runner
Description: Device wherein the means comprises a casing* and wherein the working fluid* flows to, through, and from the runner* along a path extending along the runner"s axis of rotation. The working fluid path has a ring like or annular cross section taken perpendicular to the axis of rotation, which cross section is centered about and which cross section decreases or increases in diameter along the axis of rotation.
