1. Universal impact-hinder device, comprising a body (1);

  • a guiding pin (4) arranged at the closed first end of an inside cylindrical cavity of the body (1), a spiral spring (7) on the guiding pin (4);

    a ring (5) at the opposite second end of the inside cylindrical cavity of the body (1); and

    a piston having a T-shaped head in cross section and an inside cavity in which the spring (7) is supported, which piston is capable to move until the ring (5) within the inside cylindrical cavity of the body (1), while the guiding pin (4) is within the inside cavity of the piston, wherein the T-shaped head of the piston is provided with a groove and a movable O-ring (6) within that, where the O-ring (6) has two end positions in transversal direction of the groove, in the first end position a surface of the groove having artificial damages (31) and the contacting O-ring (6) determine a first flow through capacity, where pressing the O-ring (6) into the artificial damages (31) closes partially ducts of artificial damages (31) thus reducing the first flow through capacity, and in the second end position an orifice (21) between the inside cylindrical cavity of the body (1) and the groove determines a second flow through capacity which is greater than the first flow through capacity.
