Abstract
A tank system for a construction machine includes a fuel tank having an outer tank wall that closes off a tank volume to the outside, a withdrawal tank volume, which is separated by a partition wall from a main tank volume of the tank volume and has a fuel-exchanging connection to the main tank volume, and a fuel withdrawal arrangement having a main fuel pump and a withdrawal line opening into the withdrawal tank volume for conveying fuel by the main fuel pump via the withdrawal line from the withdrawal tank volume to a fuel-consuming system region. The tank system also includes a fuel feed arrangement having an auxiliary fuel pump for conveying fuel from the main tank volume into the withdrawal tank volume.
Claims15
A tank system for a construction machine, comprising:
- a fuel tank having a tank outer wall which closes off a tank volume to the outside,
- a withdrawal tank volume separated by a partition wall from a main tank volume of the tank volume and in fuel-exchanging connection with the main tank volume,
- a fuel withdrawal arrangement having a main fuel pump and a withdrawal line opening into the withdrawal tank volume for conveying fuel by the main fuel pump via the withdrawal line from the withdrawal tank volume to a fuel-consuming system region, and
- a fuel feed arrangement having an auxiliary fuel pump for conveying fuel from the main tank volume into the withdrawal tank volume,
- wherein the withdrawal tank volume comprises a lower withdrawal tank volume region in relation to a vertical direction and an upper withdrawal tank volume region adjoining the lower withdrawal tank volume region in the vertical direction, the lower withdrawal tank volume region being separated from the main tank volume in such a way that there is no direct fuel-exchanging connection between the main tank volume and the lower withdrawal tank volume,
- wherein the lower withdrawal tank volume region is positioned in the vertical direction completely under a bottom wall of the tank outer wall in the region of the main tank volume.
