A hydraulic hinge buffer assembly for a door (50, fig 1) includes a fastening device, a buffering device and a clamping device. The fastening device 10 includes a holding mount 11 and a pivot block 12. The buffering device 20 is mounted in the fastening device, and includes a rotatable pivot pin 21 and a piston 22. The pivot pin forms the axis of rotation of the hinge and has an abutment face (211, fig 3) and a holding hook 213 formed on a central portion for co-operating with the piston. The piston is mounted transversely to the pivot pin and including an annulus surrounding it to enable oil to flow around the piston. The piston further has a pressing face 231 and a co-operating hook 232 for engaging the holding hook. The clamping device 30 is rotatable with the pivot pin, and may function to hold the door. |
