FIELD: machine building.SUBSTANCE: differential cylinder (1) for hydromechanical drive, in particularly HV switch, contains: first area (3) of pressure for work pressure loading; second area (4) of pressure; piston (2) that can move in area of movement, and that can move as function of pressure difference between the first and second areas (3, 4) of pressure; and dampening device that during movement of the piston (2) in direction of the second area (4) of pressure at one section (D) of movement area ensures additional dampening in relation to the piston (2) movement.EFFECT: creation of the hydromechanical drive to activate the electric disconnection device, in which the dampening level of the end position is regulated.9 cl, 1 dwg |
