In this embodiment, the working principle of the continuous damping control shock absorber assembly is as follows:

1) When the coil is not energized

When the shock absorber is in a compressed state, the valve body assembly 40 tightly presses the valve seat ring 70 against the end cap 60 due to the pre-tightening force of the main spring 53, and the opening pressure between the valve seat ring 70 and the valve housing 11 is large, which is shown as a large damping force for the shock absorber.

When the shock absorber is in a recovery state, wherein the vibration speed of the shock absorber is low, oil flows between the valve seat ring 70 and the end cover 60, and the pretightening force is high, and the low-speed damping force is high; as the shock absorber velocity increases, high-speed damping forces are now exhibited as oil passes between the seat ring 70 and the end cap 60, and between the tappet 51 and the valve body assembly 40.

2) When the coil is energized

The current of the shock absorber is gradually increased, the coil 31 overcomes the pretightening force of the main spring 53 firstly, then the tappet 51 moves rightwards, overcomes the spring force and reaches balance again, and the valve port flow area of the electromagnetic valve is increased in the process, and the damping force is further reduced.
