Claims
- 1. A high-pressure fuel reservoir for a common-rail fuel injection system of an internal combustion engine, comprising a tubular base body (1; 11) having a substantially circular-cylindrical interior (2; 12) disposed centrally with respect to the longitudinal axis of said tubular base body, a plurality of connection openings (3; 13) communicating with said circular-cylindrical interior, and a reduced cross section of said tubular base body (1; 11), in the portions in which said connection openings (3; 13) are disposed providing a weakening of the tubular base body in this area.
- 2. The high-pressure fuel reservoir of claim 1, wherein said connection openings (3) discharge substantially tangentially into the interior of said base body (1), and wherein one weakening (5) of said tubular base body (1) is provided in the region of each of said connection openings (3).
- 3. The high-pressure fuel reservoir of claim 2, further comprising one further weakening (6) of the tubular base body (1) in the form of a cross section reduction opposite, as viewed in cross section, each of the connection openings (3).
- 4. The high-pressure fuel reservoir of claim 1, wherein said connection openings (13) discharge substantially radially into the interior of the base body (11), and wherein one further cross section reduction providing a weakening (16) of the tubular base body (11) is provided opposite, as viewed in cross section, each of the connection openings (13).
- 5. The high-pressure fuel reservoir of claim 1, wherein said reduced cross section providing said weakening (5, 6) of the tubular base body (1; 11) is formed by a lip angle, an undercut, or a key face.
- 6. The high-pressure fuel reservoir of claim 2, wherein said reduced cross section providing said weakening (5, 6) of the tubular base body (1; 11) is formed by a lip angle, an undercut, or a key face.
- 7. The high-pressure fuel reservoir of claim 3, wherein said reduced cross section providing said weakening (5, 6) of the tubular base body (1; 11) is formed by a lip angle, an undercut, or a key face.
- 8. The high-pressure fuel reservoir of claims 4, wherein said reduced cross section providing said weakening (5, 6) of the tubular base body (1; 11) is formed by a lip angle, an undercut, or a key face.
