- a valve hole 106 is formed between both front and rear end faces of the main valve body 63, penetrating along the axis L extending in the front and rear direction.
- This valve hole 106 is formed with a switching valve air intake passage 101 located in the center in the direction of the axis L, first and second output passages 107a, 107b located on either side of it, and first and second exhaust passages 102, 103 located on either side of them and communicating with the switching valve exhaust communication passage 72.
- Valve bodies 62a, 62b are inserted on both sides of the valve hole 106 in the forward and backward directions so as to be freely slidable along the axis L. These valve bodies 62a, 62b are configured so that the acting force of the air pressure from the switching valve air supply passage 101 serves as a return force.
- first and second pistons 108a, 108b are disposed on both sides of the valve hole 106 in the axial L direction, which press the valve bodies 62a, 62b under the action of pilot air pressure.
- the first and second output flow paths 107a, 107b are located above and below the valve hole 106.
- the rear ends of the first and second output flow paths 107a, 107b open to the valve hole 106, and the front ends extend forward in the direction of the axis L and communicate with the first and second output ports 64a, 64b.
- the piston box 100 is formed with a first piston chamber 100a that opens toward the front, and a first piston 108a with a larger diameter than the valve body 62a is inserted into this first piston chamber 100a so that it can slide in the direction of the axis L.
- a second piston chamber 65a that opens toward the rear is formed in the port block 65, and a second piston 108b with a larger diameter than the valve body 62b is inserted into this second piston chamber 65a so that it can slide in the direction of the axis L.

- pilot air When pilot air is supplied to the first piston chamber 100a, the force of the pilot air pressure acting on the first piston 108a, which has a larger diameter than the valve body 62a, exceeds the force of the air from the switching valve air supply passage 101 acting on the front end face of the valve body 62a, so that the valve body 62a moves forward in the direction of the axis L.
- the switching valve air supply passage 101 communicates with the first output passage 107a, and air is output from the first output port 64a.
- pilot air when pilot air is discharged from the first piston chamber 100a, the pilot air pressure acting on the first piston 108a decreases, and the force of the air acting on the front end surface of the valve body 62a is greater, so that the valve body 62a returns to the rear side in the direction of the axis L. Then, when the first pilot supply communication passage 104a communicates with the pilot exhaust passage 105, the pilot air is discharged from the switching valve pilot exhaust passage 74 or the switching valve exhaust communication passage 72. Details of the discharge of pilot air will be described later.
- the second piston 108b moves rearward, similar to when pilot air is supplied to the first piston chamber 100a, and the switching valve air supply passage 101 and the second output passage 107b communicate with each other, and air is output from the second output port 64b.
- the valve body 62b returns to the front side in the direction of the axis L.
- the second pilot supply communication passage 104b communicates with the pilot exhaust passage 105, the pilot air is discharged from the switching valve pilot exhaust passage 74 or the switching valve exhaust communication passage 72. Details of the discharge of pilot air will be described later.

- first and second pilot solenoid valves 76a, 76b are configured as three-port solenoid valves that selectively switch and communicate the first and second pilot output flow paths 80a, 80b with the first and second pilot inlet flow paths 79a, 79b and the first and second pilot exhaust flow paths 81a, 81b by energizing and deenergizing the solenoids 76a1, 76b1.
- the first and second pilot inlet passages 79a, 79b are connected to the switching valve pilot supply passage 73 through a pilot input passage 109 formed across the pilot body 77 and the main valve body 63.
- the first pilot output passage 80a is connected to the first piston chamber 100a through a first pilot supply communication passage 104a formed across the pilot body 77 and the piston box 100.

- the pilot exhaust passage 105 is connected to the switching valve pilot exhaust passage 74 on its upstream side.
- the switching valve pilot exhaust passage 74 will be described in detail later.
- the first switching valve block 60A in this embodiment is a switching valve in the internal mode shown in FIG. 16.
- the first switching valve block 60A in this embodiment is configured so that a portion of the air supplied from the air supply port 12 of the first supply and exhaust block 10 is supplied as pilot air, and the pilot air exhausted from the first switching valve block 60A is exhausted to the switching valve exhaust communication passage 72.
- the pilot exhaust passage 105 extends across the pilot body 77 and the piston box 100, and also extends to the first exhaust passage 102 through the gap formed between the seal member 62a2 and the valve hole 106.
- the seal member 62a2 is a lip-type seal member that opens toward the front, and allows air to flow from the first piston 108a side to the first exhaust passage 102 side, while preventing air from flowing from the first exhaust passage 102 side to the first piston 108a side.
- the first and second pilot solenoid valves 76a and 76b each have a pilot valve body 82 on the front side.
- the pilot valve body 82 includes inlet valve bodies 45a and 45b and exhaust valve bodies 46a and 46b arranged in the front-rear direction and linked to each other.
- the solenoid 76a1 or the solenoid 76b1 is excited, the inlet valve body 45a or the inlet body 45b is opened to individually connect the first pilot inlet flow path 79a and the first pilot output flow path 80a, or the second pilot inlet flow path 79b and the second pilot output flow path 80b.
- a mounting hole 47 is provided at the rear bottom of the main valve body 63 of the first switching valve block 60A, penetrating in the width direction, and a connection board 48 for receiving an electrical signal transmitted from the first end block 90 is attached within this mounting hole 47.

- the first switching valve block 60A described above is an internal mode switching valve, but the first supply and exhaust block 10 of this embodiment can also be used as an external mode switching valve.
- the first supply and exhaust block 10 in the external mode is configured to receive a portion of the air introduced from the pilot supply port 36 as pilot air, and to exhaust this supplied pilot air from the switching valve pilot exhaust flow path 74.
- the pilot exhaust flow path 105 in the first switching valve block 60A of the internal mode type described above is connected to the switching valve pilot exhaust flow path 74 in the middle, and the lip-type seal member 62a2 allows air to flow to the first exhaust flow path 102 side. For this reason, it is difficult to exhaust air from the switching valve pilot exhaust flow path 74.
- an O-ring 62a3 is attached to the land portion 62a1 of the valve body 62a in place of the lip-type seal member 62a2.

- the operation of the switching valve block assembly 1 will be described with reference to Figures 1-3, 12, 16, and 17.
- the internal mode of the switching valve block assembly 1 will be described.
- air supplied to the air supply port 12 of the supply and exhaust blocks 6 and 10 is supplied from the first air supply opening 16 to the first and second pilot solenoid valves 76a and 76b of the switching valve blocks 60A and 60B, and is selectively output from the first and second output ports 64a and 64b depending on the excitation state of the pilot solenoid valves 76a and 76b.
- air returned from an external device connected to the output ports 64a and 64b is exhausted from the exhaust port 13 of the supply and exhaust blocks 6 and 10 through the switching valve exhaust communication passage 72 depending on the excitation state of the pilot solenoid valves 76a and 76b.

- the path through which the air supplied to the air supply port 12 of the air supply/exhaust block 6, 10 is output from the first and second output ports 64a, 64b of the switching valve block 60A, 60B, and the path through which the air flowing in from these output ports 64a, 64b is exhausted from the exhaust port 13 of the air supply/exhaust block 6, 10 are the same as in the internal mode described above.
- Pilot air is introduced from the pilot supply port 36 of the supply and exhaust blocks 6 and 10, and is supplied from the first pilot supply opening 20 to the pilot solenoid valves 76a and 76b of the switching valve blocks 60A and 60B.
