FIELD: automotive industry.

SUBSTANCE: invention relates to automotive industry, particularly to automotive shock absorbers. Proposed shock absorber comprises casing, cylinder, compensating chamber communicating, via throttling orifices, with the cylinder chamber, rotary controlled-from-outside ring to vary throttling orifice cross section, push rod, piston with bypass valve and blow-back valve, compression spring and guide bushing. Aforesaid rotary ring is fitted in the rod end and fixed to the compression spring end. The spring other end faces the piston and is fastened to the push rod. Ring surface in contact with the throttling orifice surface have various-cross section calibrated orifices.
