Patent ID: 6871638

Claim:
A high pressure fuel accumulation device comprising: a fuel distribution pipe; a main body whose interior constitutes an accumulation chamber for accumulating high pressure fuel, the main body being provided in a circumferential wall thereof with a through-hole radially extending from the accumulation chamber and, further, on an exterior circumferential wall thereof surrounding the through-hole and at a position substantially concentric with the through-hole with a hollowed pipe joint to which the fuel distribution pipe is fastened; and a cylindrical intermediate member having a conduit extending through an axial center thereof, the conduit being provided at a part thereof with an orifice whose inner diameter is smaller than that of any other part of the conduit and smaller than an inner diameter of the through-hole, wherein the cylindrical intermediate member is housed inside the hollowed pipe joint and sandwiched under pressure between an axial end of the fuel distribution pipe and the exterior circumferential wall of the main body around the through-hole so that the fuel distribution pipe communicates with the through-hole via the conduit.
