VEHICLE SUSPENSION DOUBLE-TUBE TELESCOPIC HYDRAULIC DAMPER Russian patent published in 2007 - IPC B60G11/26 F16F9/34 

FIELD: transport engineering.

SUBSTANCE: invention can be used in suspensions of vehicles. proposed hydraulic damper consists of reservoir with eye plate, cylinder with intake valve, piston with relief valve of extension/rebound - compression stroke, rod provided with throttling hole and return valve, guide with adjustable throttling hole and set of guides and sealing cups and rings, and upper eye plate. Ball bearings are installed in eye plates. Guide and cover are assembled into one base part - guide, in which sealing cups and rings, guide polymeric rings and needle are installed. Said needle is designed to adjust resistance at throttling mode of extension/rebound stroke directly on test stand without disassembling of said damper. Damper contains additional polymeric ring installed in scraper. Said ring prevents contact of chromium coating of rod with metal of scraper and getting of hard foreign finely divided particles into sealing unit.

EFFECT: improved serviceability of hydraulic telescopic damper under unfavorable conditions, provision of convenience in its adjustment.
