PROBLEM TO BE SOLVED: To facilitate continuous air/water supplies of an unlimited amount by one operation, and to make an endoscope apparatus and devices related to air/water supplies portable and simple.
SOLUTION: A liquid introducing opening 15 is provided on a side surface part of a cylindrical body 11 having a syringe opening 14. A piston body 12 comprises a piston part 12a, a shaft part 12b, and a pressing part 12c. An A vent hole V
A is formed in the pressing part 12c. An air passage 18 is formed in the shaft part 12b. A B vent hole VB penetrating to the side surface is formed in the piston part 12a. An internal surface passage 17b which makes the B vent hole VB communicate with the inside of the cylindrical body in a prescribed moving range D1 is formed on the internal surface member 17 of the cylindrical body 11. A spring 20 which returns the piston body 12 to an original position is provided. When the piston body 12 returns, air is introduced through the A vent hole VA , the air passage 18, the B vent hole VB , and the internal surface passage 17b, and a washing water is introduced from the introducing opening 15. Then, water and air are supplied from a syringe opening 14.COPYRIGHT: (C)2009,JPO&INPIT
