<p><P>PROBLEM TO BE SOLVED: To provide a decompression switching valve that enables reduction in the running cost and initial cost by saving the air consumption and simplifying and donwsizing equipment. <P>SOLUTION: The decompression switching valve 1A includes one valve hole 2; a main valve body 3 having air supply ports P1, P2, a first output port A, a second output port B and an air exhaust port R which are communicated with the valve hole; and a first spool 4 and a second spool 5 which are slidably inserted into the valve hole adjacent to each other. The first spool forms a switching valve section 7 that selectively connects the first output port to an air supply port or the air exhaust port, and the second spool forms a decompression valve section 10 that reduces the pressure of compressed air which is input from the air supply port, and outputs the pressure from the second output port. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
