As shown in the figure, a water supply gun 4 is attached to the water supply port of the radiator 1, and the coolant passages of the radiator 1, engine 2, and car heater 3 are evacuated and antifreeze is supplied. In order to evacuate the coolant passage, a vacuum pump 5, a separator 6, and a recovery tank 8 are installed.
It is equipped with a vacuum tank 7 with a water supply gun 4, a vacuum circuit connected to the water supply gun 4, an antifreeze supply pipe 9 and a water supply pipe 1.

トを開いて残圧を除去する。 The fluid supply system is started after the water supply gun 4 is tightly clamped to the water supply port of the radiator 1, and the vacuum port is opened and the vacuum tank 7 and vacuum pump 5 supply air in the cooling water pipes of the car heater 3, engine 2, and radiator 1. At the same time as exhausting the air and closing the vacuum port, open the liquid supply port, force the coolant with the liquid supply pump 13 to fill the cooling water pipes of the radiator 1, engine 2, and car heater 3, and finally open the vacuum port to remove the remaining liquid. Remove pressure.

タンク４へ圧送する。 In addition, since the coolant is vacuumed when removing residual pressure after filling is completed, the absorbed coolant is recovered. This causes the cooling liquid to fall from the vacuum tank 7 under its own weight into the recovery tank 8, and when the recovery tank 8 is full, the passage with the vacuum tank 7 is closed and the coolant is forcedly fed to the mixing tank 4 with air.

があつた。<Problems to be solved by the invention> In the conventional device described above, when the cooling water pipes of the radiator and engine are evacuated, the saturated steam in the atmosphere turns into moisture and moisture enters the vacuum pump. Oil and water are separated in the oil-water separation tank 14, but since the water and oil are stirred at high speed in the vacuum pump, they cannot be completely separated in the oil-water separation tank 14 and are drained together with the oil and water, so the amount of oil used is small. However, if water is mixed into the oil, the water evaporates and the sealing properties of the pump walls become poor, which affects the vacuum pump function.

Therefore, maintenance of cooling liquid vacuum filling capacity is improved. Additionally, since the water content in the lubricating oil for vacuum pumps is drastically reduced, the number and amount of water and oil being drained together from the oil-water separation tank is reduced, which has the effect of reducing the amount of lubricating oil used. .
