Abstract

A method of making a fuel supply pipe by machining a pressure pipe, or a solid rod which is subsequently bored, to have axial portions 5 of relatively small diameter axially separated by integral segments 4 of relatively large diameter, the segments acting as spacers and bearing points for a casing 3 which covers the pressure pipe. The segments have ducts 6 whereby annular cavities surrounding the axial portions of small diameter are in communication. The fuel supply pipe is suitable for pulsating, high injection pressures because there are no points of weakness in the pipe wall, where fractures might occur and as the segments are integral no frictional wear by relative movement. The pipe may be curved, with segments of large diameter at each end of the curved portion. <IMAGE>
