<P>PROBLEM TO BE SOLVED: To provide a refrigerated vehicle which keeps the temperature in a refrigeration chamber at a super low value without adversely affecting a space in a cabin. <P>SOLUTION: A fixed displacement pump 21 to be driven by an engine, a first fixed displacement hydraulic motor 22 to be driven by the discharge capacity from the fixed displacement pump, a variable displacement pump 23 which is driven by the first fixed displacement hydraulic motor to control the discharge capacity so as to ensure the predetermined target value, and a second fixed displacement hydraulic motor 24 to drive a compressor 11 by the discharge capacity from the variable displacement pump are provided in a refrigeration device of the refrigerated vehicle. The fixed displacement pump is provided in a power take-out circuit 2A in the vicinity of the engine, and the first fixed displacement hydraulic motor, the variable displacement pump and the second fixed displacement hydraulic motor are respectively provided on a fixed-speed rotation circuit 2B in the vicinity of the refrigeration chamber, and the power take-out circuit and the fixed speed rotation circuit are connected to each other via a long pipe 25. <P>COPYRIGHT: (C)2003,JPO |
