<P>PROBLEM TO BE SOLVED: To switch the operating speed of a valve for controlling the flow path of a refrigerant in accordance with the operating mode of a device. <P>SOLUTION: A cooling device includes a refrigeration cycle 500 configured by successively connecting a compressor 1A, a condenser 2A, a pressure reducer and a cooler through the flow path of the refrigerant. The cooling device includes: a signal generation part for generating pulse signals of a pulse speed corresponding to the operating mode; a stepping motor rotated at a speed following the pulse speed of the pulse signals generated by the signal generation part; and a valve 41A provided in the flow path and provided with a valve body moved so as to open and close the flow path at the speed following the rotation speed of the stepping motor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
