FIELD: transport.
SUBSTANCE: invention relates to machine building. This damper comprises cylinder and rod coupled with the bogie and body. Said rod is fitted in said cylinder and coupled with piston. Said piston is fitted in said cylinder to slide therein. Chambers of rod and piston side are composed inside the cylinder by said piston. Tank is intended for storage of fluid. First open/close valve is arranged at first channel to connect the chamber from rod side with chamber of piston side. Second open/close valve is arranged at second channel to connect the chamber with said tank on piston side. The pump is designed to be actuated at predefined rpm to feed fluid from said tank to the chamber on rod side. Engine can drive said pump at preset rpm. Section type determination unit defines the type proceeding from the rpm change between preset turn rate and actual engine rpm.
