Claims
- 1. A high-pressure fuel reservoir for a reservoir injection system of an internal combustion engine, said reservoir having a base, said base having a longitudinal recess with an essentially cylindrically shaped inner surface, said recess having a plurality of connection bores branching therefrom wherein the inner circumference of the recess has at least one rib-shaped section thereon.
- 2. A high-pressure fuel reservoir according to claim 1, wherein the rib-shaped section extends over the entire length of the base.
- 3. A high-pressure fuel reservoir according to claim 1, wherein a plurality of rib-shaped sections are formed on the inner circumference of the base.
- 4. A high-pressure fuel reservoir according to claim 3, wherein two rib-shaped sections are formed on the inner circumference of the base and are disposed opposite to each other.
- 5. A high-pressure fuel reservoir according to claim 3, wherein three rib-shaped sections are formed on the inner circumference of the base and are each disposed offset at 120° with respect to one another.
- 6. A high-pressure fuel reservoir according to claim 1, wherein an acute angle (a) is formed at the transition between a connection bore and the rib-shaped section.
- 7. A high-pressure fuel reservoir according to claim 1, wherein an end of the rib-shaped section is rounded.
- 8. A high-pressure fuel reservoir according to claim 7, wherein the end of the rib-shaped section is of semicircular shape in cross-section.
- 9. A high-pressure fuel reservoir according to claim 1, wherein the high-pressure fuel reservoir is manufactured from a drawn tube.
- 10. A high-pressure fuel reservoir according to claim 1, wherein the rib-shaped section projects inward a distance (D) of more than 2 mm compared to the cylindrically shaped inner surface of the longitudinal recess.
- 11. A high-pressure fuel reservoir according to claim 3, wherein the plurality of rib-shaped sections are disposed at the same angular distance with respect to one another on the inner surface of the longitudinal recess.
- 12. A high-pressure fuel reservoir according to claim 1, wherein at least two connection bores have an angular distance (WA in degrees °) which is a multiple of (k) of 360° divided by the number (n) of rib-shaped sections.
