The present invention relates to the rail transport. A center coupler draft gear of a rail vehicle comprises a housing with a bottom, a rod-piston, two tanks formed by the latter in the housing and filled with an elastomer. The piston has holes for overflow of an elastomer and a cavity open in the direction of one chamber, in which an axially movable disk is mounted. The latter together with said holes acts as a check valve depending on the direction of movement of the piston. The disk from the side of pressing to the rod is spring-loaded. The technical result is an increase of the speed of return of the gear to its original position. |
