ABSTRACT:
A transport refrigeration system is connected to a hydraulic system including a pump, control valves, a reservoir and a hydraulic device. When the refrigeration system is running, the hydraulic system is disabled and the diesel and compressor are run responsive to cargo refrigeration requirements. When the hydraulic system is activated, the diesel is caused to operate at a preselected speed for maximum hydraulic flow and the refrigeration electrical, if necessary, system unloads the compressor to divert more engine power to the hydraulic pump.
