<p>PURPOSE:To make it possible to miniaturize and lighten a hydraulic pump by securing an oil controlling mechanism of a hydraulic motor to drive an AC generator or car refrigerator on the side of a hydraulic motor. CONSTITUTION:In a device to drive at least either an AC generator 7 or car- mounted refrigerator 8 by rotating a hydraulic motor 3 by the hydraulic power of a hydraulic pump 2 working from the output of a car engine 1, an oil return path for returning a part of the hydraulic power from the hydraulic motor 3 to the inlet side of the motor 3 through an adjust valve 6 is provided to stabilize the hydraulic pressure of the motor 3. The oil flow adjusting mechanism of the motor 3 absorbs the fluctuation of the oil flow of the pump 2 by a variable displacement type main hydraulic motor having a piston reciprocating control mechanism and auxiliary hydraulic motor interlocking to said main hydraulic motor to regulate the rotation fluctuation of the motor 3. As a result the AC generator 7 and/or car-mounted refrigerator 8 can be stably driven. The securing of the oil adjusting mechanism in the side of the hydraulic motor makes it possible to simplify and lighten the hydraulic pump.</p> |
