Abstract
A hydraulic fluid system is disclosed and that utilizes a hydraulic motor or gear pump and a magneto-rheological fluid (MRF) brake that is interconnected with an output of the hydraulic motor. The MRF brake may utilize a rotatable rotor that is disposed within a magneto-rheological fluid and that is interconnected with an output (e.g., a rotatable output shaft) of the hydraulic motor. An electrical control signal may be provided to the MRF brake (e.g., to a magnetic coil) to adjust the viscosity of the magneto-rheological fluid, and thereby a braking torque exerted on the output of the hydraulic motor.
