[0049] Working principle: Fig.14 As shown, the gas enters from the first air inlet hole 11 and the air inlet at the right end of the ASR valve housing 40, and a part of the gas entering the first air inlet hole 11 enters the first valve cavity 12. At this time, the rear end face of the annular sealing ring portion 191 is pressed against the front end face of the radially extending edge 171. At this time, the gas cannot flow out of the first valve cavity 12, and a part of the gas in the first air inlet hole 11 enters the air inlet hole of the ASR valve housing 40 from the side through hole 111. At this time, the left end face of the first sealing elastic block 45 is pressed against the right end face of the protruding column 42 and covers the first central air outlet 421 (that is, the static iron core 44 and the moving iron core 43 are separated without electricity and are normally open). Therefore, at this time, the gas still cannot flow out;

[0050] The gas entering the air inlet at the right end of the ASR valve housing 40 first enters the central transverse cavity of the ASR valve housing 40 through the central through hole of the static iron core 44, then enters the central circulation cavity 41, then enters the first groove 24 through the side through hole formed on the side wall of the central circulation cavity 41, then enters from the side circulation groove of the ABS pressure-maintaining moving iron core 312 into the central through hole of the ABS pressure-maintaining static iron core 311 (the ABS pressure-maintaining moving iron core 312 and the ABS pressure-maintaining static iron core 311 are in a separated state, i.e., normally open), then enters into the connecting cavity 33, then enters into the central through hole of the ABS pressure-relief static iron core 321, and then enters into the sleeve body 251 from the side circulation groove of the ABS pressure-relief moving iron core 322 (the ABS pressure-relief moving iron core 322 and the ABS pressure-relief static iron core 321 The gas in the first valve cavity 12 is in a separated state, i.e., normally open), and then enters the annular groove on the outer wall of the sleeve body 251 from the side flow through groove of the sleeve body 251, and then enters the rear groove 21 through the valve cover connecting hole 255, pushing the connecting sleeve body 22 backward, pressing the rear end face of the connecting sleeve body 22 against the front end face of the radially extending edge 171 and pushing it backward, so that the buffer spring 162 is compressed. At this time, the annular sealing ring portion 191 is separated from the radially extending edge 171, and the gas in the first valve cavity 12 can enter the annular groove 13, and enter the first air outlet hole 15 from the grooves 14 formed on the rear wall surface on the left and right sides of the annular groove 13, and finally be discharged from the first air outlet hole 15, and the first air outlet hole 15 is connected to the corresponding parts of the automobile, and the corresponding pneumatic parts can be pneumatically actuated.

[0051] During operation, a pressure sensor is fixed on the sensor connecting sleeve body 19 to sense the pressure at the annular groove 13 at all times.

[0052] During operation, when the static iron core 44 and the moving iron core 43 in the ASR valve housing 40 are energized and pressed against each other, the gas entering from the air inlet at the right end of the ASR valve housing 40 cannot enter the interior, but the left end face of the first sealing elastic block 45 is no longer pressed against the right end face of the protruding column 42. Therefore, the gas entering the air inlet of the ASR valve housing 40 from the side through hole 111 will enter the middle flow cavity 41, and then, as before, continue to be transmitted, and finally, be discharged from the first air outlet through hole 15.

[0053] When the ABS pressure-maintaining moving iron core 312 and the ABS pressure-maintaining static iron core 311 are attracted (powered on), the gas cannot enter the connecting chamber 33. At this time, no gas will be discharged from the first air outlet hole 15. At the same time, when the ABS pressure-relief moving iron core 322 and the ABS pressure-relief static iron core 321 are attracted (powered on), they are reset by the buffer spring 162, which will return the connecting sleeve 22 to its original position, and the gas in the rear groove 21 at the front of the connecting sleeve 22 will enter the second groove 25 from the valve cover connecting hole 255. At this time, the bottom surface of the second elastic sealing block 35 of the ABS pressure-relief static iron core 321 no longer presses against the rear ventilation hole of the rear end plate of the sleeve part 251. At this time, the gas in the second groove 25 can flow out from the rear ventilation hole, and finally, enter the guide sleeve 16 from the middle through hole 221, and then be discharged from the air outlet hole formed on the rear end face of the first valve cavity 12 to achieve pressure relief.

[0054] During this process, part of the gas will be blown out from the gas outlet hole 283 of the gasket 282, flipping the front wall plate of the elastic sleeve body 281 forward, so that it can enter the middle flow cavity 41 to release pressure.
