Abstract
An air feeding device for endoscope system includes an air compressor that compresses air and feeds the air in a sealed space, and a pressure sensor that detects air pressure in the sealed space. Further, a pressure setting device and a pressure controller are provided. The pressure setting device is used for setting a pressure value to be achieved in the sealed space, and the pressure controller turns ON and OFF the compressor in accordance with the air pressure detected by the pressure sensor and the pressure value set by the pressure setting device. The air feeding device has a main valve. An inlet of the main valve is connected to the sealed space, and an outlet of the main valve is connected to an outlet of the air feeding device. By opening the main valve, the air enclosed in the sealed space is discharged from the outlet to strike an object at a certain pressure.
