The working process of the hydraulic shock absorber with the semicircular groove on the base is as follows: when a piston rod of a hydraulic shock absorber with a semicircular groove on a base is pulled by external force, a piston assembly moves towards a rod cavity, a compression valve core is closed, oil in the rod cavity pushes away a recovery valve core, so that the oil enters a rodless cavity, the volume of the rod cavity is smaller than that of the rodless cavity when the same stroke is carried out, the oil flowing out from a rod of the rod cavity is not enough to fill the space of the rodless cavity, a vacuum can be formed in the rodless cavity, the pressure of the oil in an oil storage cavity pushes away a compensation spring piece, so that the oil in the oil storage cavity enters the rodless cavity, when the piston rod is pressurized, the piston assembly moves towards the rodless cavity, the volume of the rodless cavity is reduced, the oil pushes away the compression valve core, the recovery valve core is closed, the oil enters the rod cavity, a part of the oil pushes away a discharge valve of a discharge valve assembly, and the oil flows back to a storage oil cylinder 4 for inputting pressure oil. The hydraulic shock absorber with the semicircular groove on the base achieves the effect of reducing the speed and the vibration due to the arrangement of the opening degree and the damping hole of the valve in the stretching and compressing processes of the piston. The hydraulic shock absorber with the base provided with the semicircular groove is reasonable in design, compact in structure and stable in performance. The vibration absorber is widely applied to vibration reduction of automobile wheels.
