It hits, effectively protects throttling set and reversing arrangement,
When needing to reduce the damping force of the present apparatus, according to above-mentioned steps shaft (25) are rotated, and make cam (26)
Proximal part trend is contacted with adjusting rod (23) right end, and under the elastic force effect of second spring (34), right side throttling set will be remote
From piston (6), under the mating reaction of upper rack (13), lower rack gear (17) and gear (15), the throttling set in left side equally can
Far from piston (6), the limiting block (10) of taper is gradually withdrawn into taper hole (7), limiting block (10) outer rim and taper hole (7) inner edge it
Between gap become larger, when piston (6) is in shell (1) interior back and forth movement, two chambers of shell (1) inner piston (6) left and right it is viscous
Liquid is because pressure imbalance flows through biggish gap between limiting block (10) outer rim and taper hole (7) inner edge, to generate relatively
Small damping force.
