<P>PROBLEM TO BE SOLVED: To provide a vehicular switching valve device including a switching valve that switches first input ports and a first output port and second input ports and a second output port independently without increasing a space. <P>SOLUTION: If first signal pressure P<SB POS="POST">SL1</SB>is outputted to a first oil chamber 68 and a second oil chamber 70 while second signal pressure P<SB POS="POST">SL2</SB>is not outputted, only a first spool valve element 62 is moved, thereby allowing only switching between first input ports 50, 52 and a first output port 54. If the second signal pressure P<SB POS="POST">SL2</SB>is outputted to a third oil chamber 72 while the first signal pressure P<SB POS="POST">SL1</SB>is outputted, only a second spool valve element 64 is moved, thereby allowing only switching between second input ports 56, 58 and a second output port 60. Therefore, the first input ports 50, 52 and the first output port 54 can be switched and the second input ports 56, 58 and the second output port 60 can be switched, respectively, and independently. <P>COPYRIGHT: (C)2013,JPO&INPIT |
