摘要： A hydraulic buffer hinge with a first hinge plate 10 and first sleeve 11, a second hinge plate 20 and second sleeve 21; and a hydraulic buffer device comprising a buffer portion (31 Fig 2) rotatably connected to a rotation component 33 with a variable receiving portion “C” formed therebetween; a resilient portion 35 having a spindle 351 and a resilient element e.g. spring 353, with the spindle partially entering the buffer portion, and a casing 37 enclosing parts of the buffer to confine movement of the buffer liquid. The top end of the rotation component is connected to the first sleeve and the bottom end of the resilient portion is connected to the second sleeve such that when the hinge is operated the buffer portion and rotation component are drawn apart against the spring increasing the size of the receiving portion. Preferably the rotation component has two helical grooves (311 Fig 2) which receive an actuating rod 331 fixed to the rotation component 333 and the rod slides in the grooves to cause linear movement. An adjustment valve may be located in a via 330, the spring may be adjusted at using a screw (Fig 4).
