1. An air feeding device for an endoscope, comprising:
- a pressure control system that controls a pressure of air within a sealed space defined within said air feeding device so as to fall within a predetermined set range;
an abnormal condition detecting system that detects an abnormal condition of at least one of the pressure within the sealed space and control of said pressure control system;
a resolving system that resolves the abnormal condition when the abnormal condition detecting system detects an abnormal condition; and
a discharge valve configured to discharge an air pulse of a predetermined duration from said sealed space to said endoscope.

12. An air feeding device for an endoscope, comprising:
-
a compressing system that compresses air within a sealed space defined within said air feeding device;
a pressure measuring device that measures a current pressure of the sealed space;
a pressure control valve provided between the sealed space and outside, a pressure within said sealed space being decreased by opening said pressure control valve;
a pressure control system that controls said compressing system and said pressure control valve so that the pressure within the sealed space falls within a predetermined set range;
an abnormal condition detecting system that detects an abnormal condition of at least one of the pressure within the sealed space and control of said pressure control system;
a resolving system that resolves the abnormal condition when the abnormal condition detecting system detects an abnormal condition; and
a discharge valve configured to discharge an air pulse of a predetermined duration from said sealed space to said endoscope. - View Dependent Claims (13, 14, 15)
