Abstract

The present disclosure relates to a saddle tank for motor vehicles, having two chambers connected to one another in their upper region via a central portion having a reduced cross-section, wherein the first chamber has an access opening for refueling and wherein a fill level-limiting valve is arranged in the second chamber. In order to prevent unwanted swash-over of fuel from the first chamber into the second chamber, provision is made according to the invention for there to be arranged, between the two chambers, a separating body which has a separating wall, which extends over the entire width of the central portion between an upper and a lower wall portion, and a pipe which extends from an opening in the separating wall into the first chamber and allows fluid communication between the first and the second chamber.

First claim

The invention claimed is:

1. A saddle tank for motor vehicles, having two chambers connected to one another in their upper region via a central portion having a tapered cross-section, wherein the first chamber has an access opening for refueling and wherein a fill level-limiting valve is arranged in the second chamber, wherein a separating body is arranged between the two chambers and has a separating wall extending over the entire width of the central portion between an upper wall portion and a lower wall portion, wherein a pipe extends from an opening in the separating wall into the first chamber such that an end of the pipe is a free end and another end of the pipe is terminated at the separating wall, and allows fluid communication between the first chamber and the second chamber, and wherein the pipe protrudes into the first chamber such that its opening is disposed above a fuel level in the first chamber, which is inclined in the direction of or swashed toward the central portion in an inclined position of the saddle tank or during a strong lateral acceleration.

2. The saddle tank of claim 1 , wherein the separating wall is part of a carrier for fuel components, which is arranged inside the saddle tank.

3. The saddle tank of claim 1 , wherein the separating wall has at least one recess or aperture, through which it is arranged on a carrier for fuel components, which is arranged inside the saddle tank.

4. The saddle tank of claim 1 , wherein the pipe extends substantially perpendicularly to the separating wall.
