一定回転制御装置。 A refrigerating compressor of a refrigerating vehicle is connected to an oil motor, and pressure fluid is supplied to the oil motor through a discharge circuit from a variable displacement hydraulic pump driven by the traveling engine of the refrigerating vehicle and equipped with a pump displacement control device. The pump capacity control device is provided with a pilot circuit connected to the discharge circuit, and the pilot circuit is opened when the pressure difference across the throttle provided in the discharge circuit exceeds a set value. A constant rotation control device for a compressor for a refrigerating machine of a refrigerating vehicle, comprising a pilot valve that connects the pump displacement control device to a tank when a pressure difference is below a set value.
