UNIVERSAL IMPACT-HINDER DEVICE
Abstract:
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 spring (7) on the guiding pin (4); a ring (5) at the opposite end of the cavity; and a piston having T-shaped head and an inside cavity in which the spring (7) is supported, which piston can move until the ring (5), while the guiding pin (4) is within the inside cavity of the piston. The T-shaped head is provided with a groove and a movable O-ring (6) within that, having two end positions in the groove. In first end position a surface of the groove having artificial damages (31) and the contacting O-ring (6) determine a first flow-through capacity, in second end position an orifice (21) between the cavity of the body and the groove determines a greater second flow-through capacity.
