Patent attributes
An integrated fluid handling apparatus 10 includes a power take off device 108 having a rotating power take off mechanism 122, a hydraulic pump 104 having a rotating fluid pump mechanism 146, a flow torque tube 106, and an electric motor/generator 102 having a rotating electric power conversion mechanism 173. A rotational power transfer system includes connector devices 128, 138, 166 and 172 that are drivingly connected to and that drivingly connect the mechanisms 122, 146 and 173 in one mode of operation. The electric motor/generator 102 includes heat exchange fluid flow passages that establish a fluid flow path to the inlet of the pump. The mechanisms 122, 146 and 173, and the connector devices 128, 138, 166 and 172 are assembled and used as a whole within a housing, without externally exposed mechanical drive connections and without externally exposed fluid connections, between such mechanisms and devices.
