Title:
A NOZZLE FOR A REFUELLING PROBE
Document Type and Number:
WIPO Patent Application WO/2010/084316
Kind Code:
A3
Abstract:
The nozzle (10) of the invention comprises a nozzle body (20) having a nozzle tip (22) for engaging a fuel hose coupling (44), the tip extending from the body, and a valve sleeve (26) for opening and closing a fuel path between the tip and the body. The tip is mounted within the body on a flexible shaft, so as to accommodate misalignment between the nozzle and the fuel hose coupling. This eliminates the need for a bearing at the end of the shaft, which causes a pressure drop in the nozzle. The shaft is axially slidable in the mounting in a first portion of the nozzle body, and may be held in the extended position of the tip by abutment with part of a second portion (100) of the nozzle body. The first and second portions of the body are joined a weak link (98), which is frangible in the event of excessive load, to release the abutment and allow the nozzle tip to travel towards the body and close the fuel path. Thus a separate shut-off valve is not required. The invention also allows the inclusion of a pressure regulator sleeve (156) for moving out of the nozzle body towards the nozzle tip in the event of excessive fuel pressure. Thus the nozzle tip can be tailor made to the aircraft to which it is fitted for providing suitable pressure regulation.
