<p>PURPOSE:To stably obtain a high output AC power and to facilitate the drive of an on-board refrigerator, by driving a hydraulic motor by means of a hydraulic pump driven by engine power, and by operating an AC generator and a compressor in the on-board refrigerator with the use of the output of the hydraulic motor. CONSTITUTION:A hydraulic motor 2 is driven by the hydraulic power of a hydraulic pump 2 operated by the output of an automobile engine 1. Oil discharged from the hydraulic motor 3 is cooled by a heat-exchanger 4 as necessary, and is then returned to the hydraulic pump 2 side. A part of hydraulic pressure from the hydraulic pump 2 is returned into the suction side of the hydraulic pump 2 through a regulator valve 6 to aim at stabilizing the hydraulic pressure of the hydraulic pump 2. Further, the hydraulic motor 3 is coupled to an AC generator 7 and a compressor 8 in an on-board refrigerator, parallelly or selectively by means of a change-over switch device which is not shown. Therefore, on-board apparatuses are driven by the generated AC power, and the cold service of a selling mobile car is ensured by driving the compressor.</p> |
