A fuel manifold preferably of plastics material adapted to supply fuel to the injectors of an internal combustion engine fuel injection device.

摘要

The manifold is formed by a first tubular element (5) adapted to define the casing of the manifold which is provided with a fuel inlet connector (7) and a fuel outlet connector (8) and an attachment flange (9) for a pressure regulator (1) adapted to maintain substantially constant the pressure within the interior of the manifold; the manifold further includes a second tubular element (12) disposed within the interior of the first, one end (13) of which is adapted to be connected to a discharge connector (4) from the pressure regulator and a second end (14) of which is adapted to be connected to the outlet connector (8) of the first tubular element; the first and the second tubular element define an annular duct (15) lying between the outer surface of the second and the inner surface of the first element and adapted to supply fuel to the seats of the fuel injectors which are formed on the first element, whilst the second tubular element defines within its interior a discharge duct (18) for fuel from the pressure regulator.
