<p><P>PROBLEM TO BE SOLVED: To provide a switching valve of a low cost of which the flow passage switching motion is sure while having a simple structure, and to provide a pump using the switching valve. <P>SOLUTION: This switching valve 1 is arranged in a pipe arrangement which is branched to discharging ports 11 and 12 in two directions, and makes a fluid flow at least through the discharging port 11 or 12 in one direction. The switching valve 1 consists of a disk body 4 which freely rotatably rotates by the pressure of the fluid at the branched section, and has a water passing section 2 consisting of a notch through which the fluid passes through the disk body 4, and a water stopping section 3. The switching valve 1 has a rotation function to rotate the disk body 4 when the disk body 4 receives the pressure of the fluid, and a stopper function to stop the rotation of the disk body 4 at a specified position. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
