Abstract
A high pressure fuel pipe construction for an internal combustion engine, such as a direct injection engine. A conduit for the fuel is open at each end and a ball having a throughbore is slidably positioned over one end of the conduit. A reinforcing sleeve is positioned inside the end of the conduit so that the sleeve extends entirely through the ball. The sleeve, ball and the end of the conduit are then brazed together to attach the ball and conduit together. A double chamfer is provided at one end of the ball throughbore to facilitate inspection of the brazing quality. Additionally, a loop is formed in the conduit and a dampener is attached to the loop.
