Abstract
A fuel rail is provided with a mounting clip in each mounting foot to allow secure connection of the fuel rail adjacent an engine manifold. The mounting clip is inserted into a mounting foot after the fuel rail has been manufactured and has a flange which overlies the top of the foot. The clip completely receives a bolt therein and when the bolt is tightened transmits a clamping force to the fuel rail through the flange of the clip. Thus, the bolt bears directly on the clip, not the fuel rail, and can be highly torqued without breaking the fuel rail.
Claims10
A fuel rail for an engine having a fuel injector comprising:
- a body;
- a passage in the body for distributing fuel to at least one fuel injector;
- a mounting foot carried by the body;
- a circular through hole in the mounting foot;
- a mounting clip constructed to be at least partially received in the through hole of the foot and having;
- an annular, radially extending flange adjacent one end of the clip constructed to engage the mounting foot and when unflexed is inclined at an acute included angle relative to the axis of the flange;
- an annular side wall of the clip adjacent the flange;
- an annular bottom wall adjacent the end of the side wall opposite the flange constructed to be received between the head of a bolt and an engine manifold;
- and
- a hole through the clip and constructed to receive the shank of a bolt whereby the clip is press-fit into the through hole of the mounting foot with the flange overlying a portion of the mounting foot and the side wall of the clip extending into the through hole of the mounting foot, the mounting clip slidably receives a bolt therethough such that the head of the bolt bears on the bottom wall and the flange exerts a force on the mounting foot to secure the fuel rail adjacent the engine.
