ABSTRACT:
A suction controller of an endoscope is provided with a valve member made of resilient material on a shiftable tube which is guided by a guide tube disposed within a support tube so that when liquid is fed said valve member is pressed against a valve seat disposed on said support tube with said shiftable tube shifted to break the communication between a suction tube and a channel of the endoscope. As a result, the liquid is no longer drawn into the suction tube during the liquid feeding and the shifting of the shiftable tube is guided by the guide tube, so that the reliable functions of the suction controller can be assured.
