Abstract
PURPOSE:To improve sealing performance and open and close a control circuit properly and in simple ways by controlling the communication state of the opened holes of a fixed valve body and a movable valve body which are made of ceramics by detecting the position relation between the both valve bodies. CONSTITUTION:In the closed valve state, the opened hole parts of a fixed valve body 18 and a movable valve body 19 which are made of ceramics are closed each other. When an opening/closing selecting switch 43 is switched to opening, a motor 28 is brought into electric conduction, and the movable valve body 19 turns, and when the opened hole part is put into the perfect electric conduction state, a microswitch 32 is turned OFF by the cam part of a transmission shaft 31, and drive is suspended. When the biting of the foreign material such as seal tape and metal piece is generated during operation, said foreign material is cut by the similar effect to a scissors made of ceramics. Further, since the ceramics valve body is used, deterioration of performance is not generated after a long period of use.
