<P>PROBLEM TO BE SOLVED: To provide a selector valve with a simple constitution, having a manual operation function and a display function. <P>SOLUTION: A shaft hole 31 for connecting a pilot chamber 21 and the outside is formed in a master cap 7, and a manually operated shaft 32 is reciprocally accommodated in the shaft hole 31. The manually operated shaft 32 is pressed from the outside and moved into the shaft hole 31, so that the manually operated shaft 32 directly presses a piston 25 to move a spool valve element 3 from the first changing position to the second changing position. The manually operated shaft 32 is formed to move to the outer side of the shaft hole 31 than the initial position, on the basis of the pressure of the pilot fluid to be supplied to a pilot chamber 21. A shaft biasing member 53 is provided, which biases the manually operated shaft 32 moved to the outside the initial position toward the inside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
