ENDOSCOPIC FLUID PASSAGE CHANGEOVER VALVE UNIT AND ENDOSCOPE

OLYMPUS CORPORATION, Tok...

1. An endoscopic fluid passage changeover valve unit comprising:
a cylinder portion having a hollow portion formed therein;
a first upstream-side fluid passage that has a downstream end thereof located on an inner peripheral surface of the cylinder
portion, and that is configured to supply a first fluid to the hollow portion from the downstream end;

a shaft that extends along a movement axis to be inserted into the hollow portion, and inside of which a communication passage
is formed, the communication passage being opened to an outside of the cylinder portion through an opening and being also
opened to the hollow portion in an inside opening located on an outer peripheral surface of the shaft;

a first seal member that is provided on the outer peripheral surface of the shaft rotatably around the movement axis, and
that is located at an angular position apart from the inside opening in circumferential directions of the cylinder portion;

a connection cap that attaches the shaft to the cylinder portion so that the shaft and the first seal member are rotatable
relative to the cylinder portion around the movement axis toward a position where the downstream end of the first upstream-side
fluid passage is blocked by the first seal member and toward a position where the inside opening of the communication passage
faces the downstream end of the first upstream-side fluid passage; and

a second seal member that is provided on the outer peripheral surface of the shaft moveably and rotatably with respect to
the cylinder portion and that is configured to keep airtight and watertight between the cylinder portion and the shaft.
