摘要：An automatic-return hinge is returned by a compression spring 12 which, on opening the hinge, is compressed between two pistons 8 moving towards each other along the axis of the hinge. The pistons are internally threaded in opposite pitches and are moved axially by an internal screw thread 7, the pistons being non-rotatable with respect to one leaf 3 of the hinge and the screw thread being non-rotatable with respect to the other leaf 1 of the hinge so that relative rotation, and consequently axial movement of the pistons, takes place on opening and closing the hinge. <IMAGE>
