Abstract

A hydraulic arrangement for turning the rotor shaft of an axial flow elastic fluid turbine rotor. The arrangement includes a variable speed hydraulic motor, the torque produced thereby being dependent upon the pressure of motive fluid supplied therethrough. The motor is connected through suitable coupling or clutch to the shaft. A plurality of sources of motive fluid each at a predetermined pressure range are connected to the motor. A flow control arrangement for selectively introducing motive fluid from each of the plurality of sources to the hydraulic motor to provide the desired torque output from the motor is provided.
