The valve spool 70 is mounted to the valve chamber and is rotatable relative to the housing 20. The valve spool 70 is provided with a plurality of spool flow passages 74. The spool flow passage 74 is formed by a circumferential surface of the spool 70 being recessed inward, and extends in the circumferential direction or axial direction of the spool 70. It will be appreciated that when the valve spool 70 is rotated to different positions, a portion of the housing passage 24 is blocked or otherwise communicated by the corresponding valve body flow passage 74, thereby allowing control of the fluid.

The multi-way valve 100 further includes a seal 60 and a plate-like base 50. The base 50 is connected to the housing 20. preferably, the base 50 is formed integrally with the cylindrical housing 22. for example, the base 50 is formed integrally with the cylindrical housing 22 as a one-piece unitary body. The base 50 has a plurality of base flow passages 54, the base flow passages 54 communicating with the corresponding housing passages 24. The base channel 54 is disposed in the base 50 and is substantially coplanar, which facilitates connection of the multi-way valve to external piping or equipment. Preferably, the housing channel 24 is directly opposite the base channel 54 and perpendicular to the plate-like base 50. The base runners 54 are arranged in a matrix, in this embodiment, a matrix of two rows and three columns is shown.

The base 50 is provided with mounting through-holes 56 to facilitate mounting of the multi-way valve 100 to external equipment or external piping.

Referring to fig. 2 to 4, the sealing member 60 includes an arc-shaped main body 62 and a plurality of through holes 64 formed in the arc-shaped main body 62. A seal 60 is mounted to the inner wall of the cylindrical housing 22 at the inner end corresponding to the housing passage 24 for enhancing the sealing connection of the housing passage 24 to the valve cartridge 70. Specifically, the cylindrical housing 22 is provided with a mounting portion 25 at a position close to the base 50 of the inner wall of the valve chamber, and the arc-shaped main body 62 of the seal 60 is fixedly mounted to the inner wall of the valve chamber through the mounting portion. Understandably, when the valve core 70 is rotated to a certain position, the through hole 64 of the sealing member 60 communicates the inner end of the housing passage 24 with the valve core flow passage 74 of the valve core 70.

To further enhance the sealing effect, the inner side surface of the sealing member 60 has a first protrusion 65, and the first protrusion 65 surrounds each through hole 64 for enhancing the sealing connection of the inner side surface of the sealing member 60 with the valve core 70. The outer side surface of the seal 60 has second projections 66, the second projections 66 also surrounding the respective through holes 64 for enhancing the sealing connection of the outer side surface of the seal 60 to the cylindrical housing 22. In addition, a recessed annular groove 28 is provided at the open end of the cylindrical shell 22 for receiving an O-ring seal 38, the seal 38 being captured by the cylindrical shell 22 and the cover 30 for enhancing the sealing connection between the cylindrical shell 22 and the cover 30. In this embodiment, a plurality of screw holes 26 are formed on the outer surface of the cylindrical case 22 near the open end, and the cover 38 is fixed to the open end of the cylindrical case 22 by screws.

The spool 70 includes a hub 71, a longitudinal partition 75, a transverse partition 76, and a peripheral partition 77. The hub portion 71 extends in the axial direction of the spool 70. A longitudinal partition 75 projects outwardly from the outer periphery of the hub 71 and extends axially and radially of the spool 70. The transverse partition 76 projects outwardly from the outer periphery of the hub 71 and extends in a transverse direction and a radial direction of the valve spool 70. A peripheral partition 77 is attached to the outer end of either the longitudinal partition 75 or the transverse partition 76, defining the outer diameter of the spool 70. The spool flow passage 74 is formed by the hub 71 and the corresponding longitudinal and

transverse partitions

75, 76.

In the present embodiment, the port formed by the spool flow passage 74 in the outer peripheral surface of the spool 70 is continuous, that is, the continuous outer peripheral surface of the spool 70 is recessed inward to form the spool flow passage 74. It is understood that the port formed by the spool flow passage 74 at the outer peripheral surface of the spool 70 may be discontinuous, i.e., the inlet and outlet ports of the spool flow passage 74 are separated by the peripheral partition 77.
