Abstract
A nozzle includes a nozzle body having a nozzle tip for engaging a fuel hose coupling, the tip extending from the body, and a valve sleeve 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. The first and second portions of the body are joined with a weak link, 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. Also a pressure regulator sleeve moves out of the nozzle body towards the nozzle tip in the event of excessive fuel pressure.
