A hydraulic system including a hydraulic power source (102) having an output and a directional control valve (106) coupled to the output of the hydraulic power source. The system also includes a hydraulic cylinder (108) coupled to the directional control valve that receives hydraulic fluid at a first port and expels it at a second port as it moves a load (114) at a movement rate, a fixed displacement motor (150) coupled the directional control valve and receiving hydraulic fluid expelled by the hydraulic cylinder and a variable displacement pump (154) attached to a drive arm (152) of the motor. |
