PURPOSE:To purify water in the tank by furnishing a control device, which is actuated by a sensor for the condition of water, having thereby proper adjustment of the water, and by replacing water in the receiver tank automatically. CONSTITUTION:When the water level attains the upper limit point (water increases when the water contained in the inhaled atmosphere liquefies), an electric signal is given from a level sensor 12, which is to sense the water level in a receiver tank 7, to actuate a control device 13. Thus a solenoid valve 14 is opened to exhaust the water 15 from the receiver tank 7 as well as a water supply device 4 is released to supply new water to a compressor 1. When exhaust of the water 15 depress the water level in receiver tank 7 to the lower limit point, the solenoid valve 14 is shut and the water supply device 4 also. Thus the 15 water in the receiver tank 7 can be purified through automatic replacement. |
