Abstract:
A method for making a through opening in a high-pressure fuel reservoir that has an elongated, tubular jacket body (1), which body is provided in the longitudinal direction with a continuous recess (2), open on at least one side, that forms the interior of the high-pressure fuel reservoir, and the through opening (5) is made in the jacket body (1) in the form of a bore by a machining tool in such a way that this opening discharges into the continuous recess (2), the method comprising the steps of pressing a pressure part (13) against the inner wall (4) of the jacket body (1) in the region of the expected outlet of the through opening (5) before the through opening is made, then with the machine tool, drilling through the jacket body (1) some distance into the pressure part (13).
