[0025] Reference Figure 1 And in combination with Figure 6 , the valve body 2 has a chamber 21 for placing the valve core 1. The chamber 21 is adapted to the outer shape of the valve core 1, which enables the valve core 1 to rotate within the chamber 21. And the chamber 21 has a first oil outlet 22, a second oil outlet 23, a third oil outlet 24, a fourth oil outlet 25, and an oil inlet 26. The oil inlet 26 is directly communicated with the central diversion hole 11, while the first oil outlet 22, the second oil outlet 23, the third oil outlet 24, and the fourth oil outlet 25 are all located in a first plane, and the first plane is parallel to the axis of the valve core 1.

[0026] There are a total of fifteen combinations of the conduction and closure of the first oil outlet 22, the second oil outlet 23, the third oil outlet 24, and the fourth oil outlet 25. Therefore, the valve core 1 is evenly divided into fifteen sector areas. When the valve core rotates to different positions, it corresponds to a combination method. By rotating the valve core 1, the first oil outlet 22, the second oil outlet 23, the third oil outlet 24, and the fourth oil outlet 25 are communicated with the diversion grooves in different sector areas, so that the distribution of the liquid flow direction can be controlled.

Then, through combination with different diversion grooves and connection with the central diversion hole 11, the distribution of different oil outlets is achieved. For example, when the first oil outlet 22, the second oil outlet 23, the third oil outlet 24, and the fourth oil outlet 25 are aligned with the first sector area 161, only the first diversion groove 171 located in the first annular belt 12 is provided in the first sector area 161. Thus, only the first oil outlet 22 is conducted, and the rest are in a closed state. If it is rotated to the sixth sector area 166, at this time, the first oil outlet 22 is connected to the first diversion groove 171 of the first ring, the second oil outlet 23 is connected to the second diversion groove 172 of the second annular belt 13, the third oil outlet 24 is in a closed state, and the fourth oil outlet 25 is connected to the seventh diversion groove 177 of the fourth annular belt 15.

[0028] In order to better rotate the valve core 1, a driving rod is further provided on the valve core 1. Correspondingly, the valve cover 3 is provided with a mounting hole, and the driving rod passes through the mounting hole. The driving part can be a stepping motor. By precisely controlling the rotation angle, the driving rod can be driven to rotate, and the rotation angle of the valve core 1 can be precisely controlled, so as to achieve the distribution of the liquid flow direction.
