Fuel distribution, for an internal combustion motor, has an injection molded plastics shrouding at the junction between the distribution tube and branch connections to the injectors with sleeve sections around them

摘要

The fuel distributor (3) at an internal combustion motor, to carry fuel to the cylinder injection valves, has a tube (4) to carry fuel under pressure with branch tube connections (5) to the injectors with a mounting bush (6). The tube, connection and mounting are of metal. An injection molded plastics component (9) shrouds each mounting and branch connection, with a sleeve (14) around the distribution tube. The shrouding has an additional sleeve (15) around the branch connection, forming a junction between the branch connection and the tube, with the mounting at the junction.
