Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0032] figure 1 Shown is a structural schematic diagram of a typical damping multi-mode switching shock absorber in which the oil flow path of the shock absorber is determined by the on-off state of the switch solenoid valve. The shock absorber changes the oil flow path of the shock absorber in the recovery stroke and the compression stroke by controlling the on-off state of the two switching solenoid valves 12 and 13 . For example, when the switch solenoid valve 12 is closed and the switch solenoid valve 13 is opened, during the recovery stroke, the oil in the recovery chamber 1 flows to the compression chamber 5 through two paths, one is through the recovery valve 4, and the other is through the single Directional valve 8 and switch solenoid valve 13; during the compression stroke, the oil in the compression chamber 5 also flows to the recov...
