    • 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.
    • 用于内窥镜系统的空气供给装置包括:空气压缩机,其压缩空气并将空气供给到密封空间;以及压力传感器,其检测密封空间中的空气压力。 此外,设置有压力设定装置和压力控制器。 压力设定装置用于设定在密封空间中要实现的压力值,并且压力控制器根据由压力传感器检测到的空气压力和由压力设定装置设定的压力值将压缩机接通和关闭 。 空气供给装置具有主阀。 主阀的入口连接到密封空间,主阀的出口连接到空气供给装置的出口。 通过打开主阀,封闭在密封空间中的空气从出口排出,以一定压力冲击物体。
