<p>A closed-ended fluid-filled cylindrical housing has two piston rods with end stop buffers, with spring-subjected pistons fitted with a damping device, on sliding doors. Each rod (16, 17) has a piston (23, 24) screwed with axial movement, on its inside threaded end (19, 20), which has an axial hole (27, 29). The holes are linked to the space behind the pistons by transverse holes (28, 30) in the rods. The hole (27) in one rod tapers towards the inside end, while the other rod end has a fitting axial tube piece (31). Springs (33, 34) are fitted between the pistons, which have a conical surface (37, 38; 41, 42) facing matching closing-lid inside surfaces.</p> |
