Abstract:
To fill a C/P oil without using a vacuum pump.
The air is expelled from a ventilator hole 23 in a pressure- resisting container 20 by leading in a low pressure coolant from a compressor 31 to be an oil filling object to the pressure-resisting container 20, and furthermore, when a C/P oil is filled, a high pressure coolant is led in from the compressor 31 to the inside of the pressure tight container 20, and the C/P oil is filled into the compressor 31 from its low pressure side 32 by the pressure of the high pressure coolant. The finishing of the C/P oil filling is confirmed by a sight glass 28.
