## Abstract

A fuel feed device for attachment to a cylinder head of an internal combustion engine has at least one fuel distribution element extending along a longitudinal direction, and at least one connecting element extending transversely to the longitudinal direction, wherein the connecting element can be used to connect the fuel distribution element to the cylinder head. The fuel feed device further includes at least one reinforcing element which is connected, on one hand, to an outer surface of the fuel distribution element and, on the other hand, to the connecting element outside the fuel distribution element.

## Claims

### Claim 1

A fuel feed device for attachment to a cylinder head of an internal combustion engine, comprising:
at least one fuel distribution element extending along a longitudinal direction,
at least one connecting element extending in an axial direction transverse to the longitudinal direction and constructed to connect the at least one fuel distribution element to the cylinder head, and
at least one reinforcing element, which is connected, on the one hand, to an outer surface of the at least one fuel distribution element and, on the other hand, to the at least one connecting element outside the at least one fuel distribution element,
wherein the at least one reinforcing element comprises at least one through-opening configured for filling a receiving space disposed between the at least one reinforcing element and at least one of the at least one connecting element and fuel distribution element with a connecting means for materially connecting the at least one reinforcing element with at least one of the at least one connecting element and fuel distribution element.

### Claim 2 (depends on 1)

The fuel feed device of claim 1, wherein the connecting means comprises a solder introduced into the receiving space.

### Claim 3 (depends on 2)

The fuel feed device of claim 2, wherein the solder connects the at least one connecting element to the at least one fuel distribution element.

### Claim 4 (depends on 1)

The fuel feed device of claim 1, wherein the at least one connecting element penetrates at least partially the at least one fuel distribution element.

### Claim 5 (depends on 4)

The fuel feed device of claim 4, wherein the at least one connecting element penetrates a fuel distribution channel of the at least one fuel distribution element.

### Claim 6 (depends on 1)

The fuel feed device of claim 1,
wherein the at least one connecting element protrudes from the at least one fuel distribution element from both a top side and a bottom side of the at least one fuel distribution element in the axial direction of the at least one connecting element, and
wherein the at least one reinforcing element is arranged on the top side of the at least one fuel distribution element and connected, on one hand, to an outer surface of the at least one fuel distribution element and, on the other hand, to the at least one connecting element outside the fuel distribution element,
the fuel feed device further comprising
at least one additional reinforcing element arranged on the bottom side of the at least one fuel distribution element and connected, on one hand, to the outer surface of the at least one fuel distribution element and, on the other hand, to the at least one connecting element outside the fuel distribution element.
