DEFINITION

Classification: 417/369

(under subclass 366) Apparatus in which there is provided a divided flow path or pump fluid which has been acted upon by the pumping member of said pump, one branch of said divided

flow path serving to direct pump fluid to the motor or part thereof.

(1) Note. To fall within the scope of this definition, flow passage means must be present for the express purpose of providing a divided flow path. Mere accidental divided flow paths through or around a motor of conventional design, in the absence of passage means provided for such purpose, is excluded, e.g., one flow path between electric motor field coil and casing and another between the field coil and armature is not considered classifiable under this definition.
