Abstract
A spring clip includes a first portion including a bridge connecting spaced elongate fingers adapted to straddle a body portion of the fuel injector and be receivable in a receiving portion of a fuel rail cup. The elongate fingers include a reverse bend at a midpoint therealong and terminate in a bridging portion. The bent elongate fingers define finger segments on each side of the reverse bend. The finger segments diverge from the reverse bend part way toward the bridge and bridging portions and converge thereafter to form generally diamond shaped spring elements. A second portion of a generally planar shape having spaced legs engages slots in the injector body. The second portion includes a wall portion extending generally perpendicular to the spaced legs and connects with the bridging portion. When the injector is mounted in the fuel rail cup, the legs are received in slots in the injector body and the elongate finger segments are compressed between the fuel rail cup and the injector body. The fuel injector is clamped between the legs and the fingers with a force toward the head of the engine by the compressive load of the finger segments. The clip is yieldable to avoid overload…
