Claims (16)

1. A regulator valve, comprising:

The electromagnetic valve assembly is provided with an inlet flow passage and an outlet flow passage and is used for controlling the on-off between the inlet flow passage and the outlet flow passage;

a one-way valve assembly is disposed within the outlet flow passage, the one-way valve assembly configured to permit one-way fluid communication from the inlet flow passage to the outlet flow passage.

2. The regulator valve of claim 1, wherein the check valve assembly divides the outlet flow passage into a first sub-flow passage and a second sub-flow passage, the first sub-flow passage and the second sub-flow passage communicating when the check valve assembly is in an open state to allow fluid to flow from the inlet flow passage through the first sub-flow passage to the second sub-flow passage, the first sub-flow passage and the second sub-flow passage not communicating when the check valve assembly is in a closed state.

3. The regulator valve of claim 2, wherein the first sub-flow passage is closer to the inlet flow passage than the second sub-flow passage, the first sub-flow passage having a pressure greater than a pressure of the second sub-flow passage when fluid flows from the inlet flow passage to the outlet flow passage to place the one-way valve assembly in an open state, and the second sub-flow passage having a pressure greater than a pressure of the first sub-flow passage when fluid flows from the outlet flow passage to the inlet flow passage to place the one-way valve assembly in a closed state.

4. The regulator valve of claim 3, wherein the check valve assembly comprises a receiving cylinder and a valve core assembly, the receiving cylinder being fixed to an inner wall of the outlet flow passage to divide the outlet flow passage into the first sub flow passage and the second sub flow passage, the receiving cylinder having a valve port, the valve core assembly being reciprocally movable to open or close the valve port to place the check valve assembly in the open state or the closed state.

5. The regulator valve of claim 4, wherein the inner diameter of the valve port gradually decreases in a direction from the second sub-flow passage to the first sub-flow passage.

6. The regulator valve of claim 5, wherein the valve cartridge assembly comprises a valve cartridge that is selectively sealingly engageable with the valve port, the valve cartridge being at least partially tapered to the valve port.

7. The regulator valve of claim 4, further comprising a first seal disposed between the valve core assembly and an inner wall of the valve port.

8. The regulator valve of claim 4, further comprising a stop assembly, wherein the receiving cylinder is secured to an inner wall of the outlet flow passage by the stop assembly.

9. The regulator valve of claim 8, wherein the stop assembly includes a first stop and a second stop, the first stop and the second stop being located at opposite ends of the receiving cylinder, respectively, to limit movement of the receiving cylinder in a flow direction of the outlet flow passage.

10. The regulator valve of claim 9, wherein the first limiting member is located at an end of the accommodating cylinder near the first sub-runner, the first limiting member is a clamping member, the first limiting member is adapted to be clamped with an inner wall of the first sub-runner and is abutted with an end of the accommodating cylinder near the first sub-runner, and/or the second limiting member is located at an end of the accommodating cylinder near the second sub-runner, and the second limiting member is adapted to be fixed to an inner wall of the second sub-runner and is abutted with an end of the accommodating cylinder near the second sub-runner.

11. The regulating valve according to claim 10, wherein the inner wall of the first sub-runner is provided with a groove, the first limiting member is adapted to be clamped in the groove, and/or the second limiting member protrudes out of the inner wall of the second sub-runner and is integrally formed with the inner wall of the second sub-runner.

12. The regulator valve of claim 4, further comprising a second seal disposed between the receiving cylinder and an inner wall of the outlet flow passage.

13. The regulator valve of claim 4, wherein the one-way valve assembly further comprises a spring that abuts between the receiving cylinder and the valve cartridge assembly to provide a return force to the valve cartridge assembly.

14. The regulator valve of claim 13, wherein the valve cartridge assembly comprises a valve stem and a valve cartridge fixedly connected, the valve cartridge for selective sealing engagement with the valve port, one end of the spring abutting the receiving cylinder, the other end of the spring abutting an end of the valve stem remote from the valve cartridge.

15. A thermal management system comprising a regulator valve according to any one of claims 1 to 14.

16. A vehicle comprising a thermal management system according to claim 15 or a regulator valve according to any one of claims 1-14.
