Embodiment
[0023] Such as figure 1 As shown, the automotive shock absorber with capillary variable damping in series in the present invention includes a cylinder body 2 and a piston 3 placed in the cylinder body 2. The inside of the cylinder body 2 is bounded by the piston 3 and is divided into an upper oil tank 2-1 And lower oil tank 2-2, also comprises the capillary tube group that is formed by many capillary tubes 5,7,9,11 connected in series, is all connected in parallel with the electromagnetic valve 6,8,10 that plays by-pass effect at the both ends of every capillary tube 12. The capillary tubes connected in series form two general ports, one of which communicates with the upper oil chamber of the cylinder body, and the other general port communicates with the lower oil chamber of the cylinder body.
[0024] The capillary includes a No. 1 capillary 5, a No. 2 capillary 7, a No. 3 capillary 9 and a No. 4 capillary 11; the solenoid valve includes a No. 1 solenoid valve 6 connected in...
