DEFINITION

Classification: 415/53.1

Cross flow runner:

(under subclass 52.1) Device comprising a runner* blade* row which forms a hollow cylinder. The working fluid* in the device flows from a position outside and on one side of the cylinder through the blade row to a position inside the cylinder and then again through the blade row to a position outside and generally on the other side of the cylinder.

(1) Note. The working fluid* usually flows in a direction perpendicular to the runner's axis of rotation.

(2) Note. Cross flow-type runners may also be referred to as transverse flow runners.
