The first and second sheet support blocks 110 and 120 have the same structure and function, and in the structure of the valve train 10 of the embodiment shown in fig. 2, the functional structure surfaces of the first and second sheet support blocks 110 and 120 are arranged opposite to each other. Specifically, the first and second sheet support blocks 110 and 120 may be used for a sheet support block of a compression valve train, and may also be used for a sheet support block of an extension valve train.

In this embodiment, the first sheet supporting block 110 is a sheet-shaped cylinder as a whole, that is, the diameter of any cross section of the first sheet supporting block 110 is greater than the height of the first sheet supporting block 110, the first sheet supporting block 110 is provided with a through hole 114, and the size and shape of the through hole 114 are matched with the size and shape of the shaft pin 600, so that the shaft pin 600 passes through the through hole 114. In one embodiment, the through hole 114 penetrates the center of the first sheet support block 110 along the axial direction of the first sheet support block 110 (i.e. the height direction of the first sheet support block 110), i.e. the center of the through hole 114 coincides with the center of any cross section of the first sheet support block 110. In other embodiments, the first valve sheet supporting block 110 is a rectangular parallelepiped in sheet shape, and the through hole 114 is opened in the same manner as: the through hole 114 penetrates through the center of the first sheet support block 110 along the axial direction of the first sheet support block 110 (i.e. the height direction of the first sheet support block 110), i.e. the center of the through hole 114 coincides with the center of any cross section of the first sheet support block 110.

In the first sheet support block 110, the sheet support surface 111 is an annular plane of the first sheet support block 110 facing the compression valve set 200, and similarly, the sheet support surface may also be an annular plane of the second sheet support block 120 facing the extension valve set 300. The through hole 114 penetrates the sheet support surface 111 to form an inner edge of the first sheet support block 110, that is, the circumference of the through hole 114 forms an inner circle of the sheet support surface 111 (i.e., the inner edge of the first sheet support block 110). The valve sheet support surface 111 is used for adjusting the stretching or compressing amplitude of the valve sheet in the valve system 10, and increasing the valve sheet support surface after the valve sheet in the valve system 10 is stretched to the maximum amplitude, so that the service life of the valve sheet is prolonged.

Specifically, the supporting boss 112 is vertically protruded at an inner edge (i.e., an inner circle of the sheet supporting surface 111) of the sheet supporting block 110 in a direction toward the compressing valve sheet set 200, that is, the supporting boss 112 is vertically protruded at a circumference of the through hole 114 in a direction toward the compressing valve sheet set 200. In the present embodiment, the support boss 112 has a hollow cylindrical shape as a whole, that is, any cross section of the support boss 112 has a circular ring shape. The support boss in the embodiment of the application is used for replacing the minimum valve plate group in the valve system 10, parts in the valve system 10 are reduced, the manufacturing cost of the valve system 10 is reduced, and the support boss can also support the valve plates in the compression valve plate group 200. In this embodiment, the support bosses 112 are in the shape of a regular cylinder perpendicular to the central opening.

The spoiler edge 113 is protruded on the valve sheet supporting surface 111 in a direction toward the compression valve sheet set 200, and similarly, the spoiler edge of the second valve sheet supporting block 120 is protruded on the valve sheet supporting surface in a direction toward the extension valve sheet set 300. Specifically, the spoiler 113 is vertically protruded at the outer edge of the vane support block 110 in the direction toward the compression valve plate set 200, that is, the spoiler 113 is vertically protruded at the outer circle of the vane support block 120 in the direction toward the compression valve plate set 200. In the present embodiment, the spoiler 113 is a hollow cylinder, i.e., any cross section of the spoiler 113 is circular. The fluid disturbing edge 113 in the embodiment of the application is used for improving the smoothness of oil in the shock absorber when the shock absorber valve block is opened or closed, so that the shock absorber valve block is prevented from being influenced by vortex when being opened or closed, the damping quality of the shock absorber is further improved, and the service life of the valve block is prolonged.

In the embodiment of the present application, the valve sheet supporting block in the valve train 10 not only can play a role of supporting the conventional valve sheet supporting block, but also can play a role of supporting the valve sheet group by the minimum valve sheet in the conventional valve sheet group. Therefore, the difference between the compression valve plate set 200 and the extension valve plate set 300 in the valve train 10 and the conventional valve plate set is that the minimum valve plate of the conventional valve plate set is eliminated, so that the number of parts in the valve train is reduced, the structure is more simplified, and the cost of the valve train is reduced.

In this embodiment, the top surfaces of the valve plate supporting surface 111 and the supporting boss 112 are not in the same plane and are parallel to each other, the top surfaces of the valve plate supporting surface 111 and the spoiler edge 113 are not in the same plane and are parallel to each other, and the protruding heights of the supporting boss 112 and the spoiler edge 113 may be the same or different.
