Abstract
An air and liquid supplying device has an air pump, a first feed liquid tank containing a first liquid, and a first selector valve connected to a feed air passage and a feed liquid passage of an endoscope. The pump is connected to the first selector valve by a air supply passage and the liquid tank is connected to the valve by a liquid supply passage. The air supply passage is connected to the tank through a pressurizing passage. The first valve is shifted between a first position where air from the pump is fed into the feed air passage and a second position where the first liquid is fed into the feed liquid passage. A second feed liquid tank containing a second liquid is connected to the air supply passage between the pump and the pressurizing passage. A second selector valve is connected to the air supply passage and shifted between a first position where air from the pump is fed into the air supply passage, and a second position where the second liquid is fed into the air supply passage.
