HYDROSTATIC COUPLING Russian patent published in 2004 - IPC

FIELD: mechanical engineering; devices for transmission of rotation in drives of heavily loaded technological equipment.

SUBSTANCE: proposed hydrostatic coupling is just protective elastically deformed coupling consisting of two members kinematically linked by means of transfer unit and hydraulic cylinder whose piston chamber is hydraulically connected with damper and hydraulic accumulator through controllable hydraulic distributor provided with coupling torque control system; inlets and outlets of hydraulic distributor may ensure connection of hydraulic cylinder with damper and hydraulic accumulator in turn. Rod chamber of hydraulic cylinder is hydraulically connected with hydraulic accumulator through hydraulic throttling valve.

EFFECT: dampening of piston vibrations at reverse stroke of hydraulic cylinder.
